To anticipate a couple of questions:
The sensor unit needs to be mains-powered and also contains a temp/hum sensor. The unit can be located inside or out, but while there's a protective outer case that should be used outside to help with mounting, there's no formal radiation shield so best located outside in a shaded spot. The data unit then connects via WiFi (only) into a LAN.
Airlink uploads directly to weatherlink.com, but is fully independent of any local Vue or VP2 stations. IOW the only data integration happens at weatherlink.com.
Data should be available via the v2 API of weatherlink.com and there will also be a local API.
-
Nice to see Davis designing this product to have a local network API like the WLL. Surely the various popular currently weather software will soon evolve to support this. I'm referring to Cumulus MX, Meteobridge, Weather-Display, and WeeWX.
-
Interesting. Looks like competition coming to the PurpleAir sensor.
-
on my shopping list ..nice especially as it is stand alone as well ..
-
weather display software already supports numerous air quality sensors so will be able to easily support this once the api is known etc
-
I really wish someone would develop an AQI monitor with solar ability. I would definitely purchase and install for the good of the community to go along with my Vue, but I don't want to run/install special wiring for a clean install and I'm not just going to plug in a spot that is subject to potential rain and can be susceptible to theft.
-
I'll take a punt & guess it's based on a Sensirion SPS30 (https://www.sensirion.com/en/environmental-sensors/particulate-matter-sensors-pm25/).
I Bought a couple last year with the intention of running them on a micro.
Still haven't bot past reading it via their Evaluation software.
It's protocol is well documented & the device supports Serial TTL or I2C.
Looking at their documentation the layout of the ports fits the above device.
Sensor alone was circa $80.00 AUD.
Even sitting in my office on the desk, the device is extremely responsive.
Cheers.

I think probably Planform rather than Sensirion (unless Planform have Sensirion inside eg as an oem, but I doubt that).
-
I think probably Planform
Do you have a link for that?
Google is coming up a bit blank.
Not meaning the Plantower?

Sorry, yes, Plantower was what I meant! Trying to do too many things at once!
FAOD it is definitely Plantower - it says so on the inner cover for the sensor module
-
I think probably Planform rather than Sensirion...
I'm taking a wild guess for course; not a lot to go on from those images.
The only real references are the power plug. Not much in the coffee table image.
Edit, Other reference is the timber post, which could be guessed as a 4x4".
Two of the specs that can be lifted directly from the Sps30 data sheet are:-
• Accurate: Measures particulates as small as 0.3 micrometers with an accuracy of +/-10 micrograms per cubic meter in concentrations.
When I received my first sensor, it's small size surprised me, 40x40x12mm.
Tiny compared to the other ones I've acquired.
The thing that jumped out at me though when I saw the first image without the cover was the similarity in the layout to one of the images in the application notes on their site.
This one.

Edit.
If that's an Amazon Echo sitting beside it on the table etc in the linked page, that would be an 88mm wide reference.
https://www.weatherstations.co.uk/wp-content/uploads/Airlink-indoors.jpeg
But again, I'm just making wild guesses.

is there a link somewhere to the api for this new sensor? :)

I'm also guessing this really isn't a Davis device since I cannot see this listed on the FCC's list.
Last two devices listed are:
IR2DWW6805 2019-06-26 Weather data gateway with Wifi/Ethernet interface (EnviroMonitor IP Gateway)
IR2DWW6100 2019-06-26 Weather data receiver with Wifi/Ethernet interface (WLL)
I even used the Search of the FCC database but these are the last two devices submitted for FCC approval by Davis Instruments. the only other thing is it is awaiting approval, but usually you still see the device listed on the FCC website.

Do you have a pointer to the local API for this, even if it's in draft form ?
One thing that concerned me with WeatherLinkLive is that you can't get all the information locally and rapidly. It seems to permit enabling wind reports via UDP broadcast, but there didn't seem to be a way to enable LOOP data via UDP for the other sensors. Seemed a little half-baked to me.
-
wind and rain data is data that changes most often
so that is available via UDP at a fast rate without having to keep on requesting it
all other data is still available from the WLL bridge via HTTP GET

Being dependent on their API to retrieve your own data would be an unfortunate limitation.

How else would you access data from a digital device except via an API? And usually it's the manufacturer who writes the API for their own device - not sure how else it might work?

it would not be that difficult to sniff the data in one or other if its over a local network i.e home router etc..but for now just have to wait till we can get our measly hands on one.. fwiw made my day when i saw this announcement in Davis we trust..
-

True, but surely you would still have to either know or to reverse engineer the API to make any sense of the data. (Really I'm just quibbling with the idea that an API is unnecessary :-) )
-
api is necessary it serves a wider audience and is a benefit however those that know if its sending data over your local network via wireless or lan then its not so difficult to capture that data . but for now we can only assume and that is never a good thing only time will tell . boris at meteobridge is already trying to source further info , i have ordered one through my uk friend but you know how it is for us in turkey so late november is more of a likelihood for me .
-

You will not be dependent on the API to retrieve your own data. You'll be dependent on the mobile app or the Davis website. But because of the API other developers will be able to leverage the API so that they can provide you other solutions to have at your data. I'm not sure what else you are expecting.
Before networked IoT devices were common, geting data via USB was common. But that too required the manufacturer to provide the compatible software application. And likewise 3rd party developers made software to understand the USB port data output.
Nothing has changed. You want data and you need to either use what the company provides or rely on a developer to provide an alternative solution.
So what are you asking for? I don't understand your comment.

We I see API, I assume we mean an HTTP request to a Davis/Weatherlink server. This means you need a connection to the internet to even store your data, as well as retrieve it.
Considering your reply, are we then talking about accessing the internal storage of the device rather than a server request?

Airlink makes data available in two distinct ways:
1. It uploads to a station at weatherlink.com and the data can then be accessed in the usual ways via the Weatherlink phone app or the browser app and with current data free, but past data subject to a Pro plan;
2. There is a local API whereby any local device can make an HTTP request and receive a snapshot of current data. As far as I know there is no local data storage in Airlink (ie the equivalent of archive or logged data) so a local API request will just return the set of current readings. Any local data storage will need to be done by the requesting device.

Some context. Currently I don't use any of the standard Davis logging solutions. I have a Meteostick connected to a Raspberry Pi. Capturing data mid air, so to speak, and writing it to a local databse. In my setup, I only need an internal network. I'm not immediately dependent on the internet or servers from other parties.
When we talk about an API, I'm assuming that means I would need to request my own data from the server, making the setup dependent on a working internet connection and third party server availability, with possible delay depending on how long it takes for an upload to become available to me.

Ah! That would be perfect. I guess all one would need to know is the refresh rate to determine your data polling interval.
-

I've not tested the local API myself yet, but the specs say that PM1/2.5/10 readings update every minute, so certainly no point in polling more often than that. I don't know about the AQI indexes - these may be updated less often.

Okay I can see your misunderstanding. The use of API does not mean that the Internet is required to get data. There are API that work over the Internet and there are API that work on your local network. In the case of WLL and this new Davis Airlink the device itself has an API that can be used by an application to get live data. The software talks directly to the device.

Bottom line, definitely getting this one when it becomes available. :-)

Mains adapter is 5v 1A. The 5v current draw is stated as 'Average: 100mA; Peak: 500mA'
NB It looks like there will be a version supplied with a USB lead (presumably rather than a mains adapter).
-
It looks like Davis are going over to two part USB leads plugging into a localised mains plugs. I've seen this in the 6152UK station this month with the cardboard box being replaced by a plastic heat sealed bag containing the two components.

No need for a FCC certification on this one, since the only communication is via a Wi-Fi module that is separately certified. The product is Davis designed, manufactured and tested in the USA.

Supporting documents are now up and available to purchase from Davis

Yep we now know. the hardware however is a Plantower A003 (or a derivative) of it. the senor and wifi module will be made elsewhere, Assembled and firmware uploaded by Davis and then tested.

It'll be interesting to see how this performs compared to PurpleAir.

If this is representative of the Plantower PCB manufacturing process, I say "no thanks".
(http://www.plantower.com/upload/ueditor/image/20160809/14707226741901532.jpg)
You would think that they could clean up the board for their promotional photos on their web site. Maybe it was out in the field for a couple of years.
This is their CO2 sensor, but they are probably built on the same manufacturing process.

Please do. I am also interested. I am going to see what Scaled Instruments is selling them for since he sells everything less than MSRP. I am guessing around $150.

Our Airlink arrived today. The box is remarkably small. Installing it permanently in a fashion that's rainproof (even in high wind) may be a bit of a challenge; the power supply in particular will require special treatment. Before winter I'll have to do some engineering.
Setup (using a cell phone and Bluetooth and existing WiFi) was trivial and trouble free. The air quality started uploading to the Weatherlink site within a minute. The local API posted on the hosiene... forum works fine: display the web page http://<airlink_ip_address_or_host_name>/v1/current_conditions and you get a JSON formatted document that is easy to parse. For details, see https://weatherlink.github.io/airlink-local-api/
The funny thing is that the device arrived two weeks late (and still remarkably early, we live about an hour from Davis' headquarters in Hayward): We live right next to one of the large fires in California, and about two weeks ago, when the CZU fire was raging at its worst (and we got evacuated), the air quality here was such that you couldn't go outside without coughing. The nearby PurpleAir stations reported AQI values of about 600, and then many of then went offline (we had widespread power/internet outages, and about 1500 houses have been destroyed). So today, the sun is somewhere between red and yellow, and the AQI is about 120. It would have been fun to have an air quality measurement device during the height of the smoke.

The airlink is (like most other things around the home) on an internal network, and not visible on the the internet. Does this help:

I pre-ordered one from Scaled Instruments last night. $123 and change. I have no idea when I'll get it, but it should be this month. I agree the power supply sucks for an item meant to be used mainly outside. I think they could have come up with a different connector system as an add on purchase to use it outside. I would gladly pay $20 for, say, a 15 foot connector with a wall wart or some sort of one-piece transformer at the plug in. I also think they could have avoided the whole issue and built the power supply unit right inside the thing in order to be able to use a standard AC plug.
It will be interesting to see what other changes this new Davis company decides to make especially since people are already complaining about customer service and phone wait times.
-
Mine is due to be delivered tomorrow from Davis. Since Brian has built connectivity into WD for this, I wonder how I could use whatever is uploaded to WD into the Alternate Saratoga template.
-
@ralphbsz ...
Interesting ... yours is already being referred to as the 'old firmware' :shock:
Looking at your posted data - look at last 24h value, you should have stayed indoors :shock:
My parser won't work on your data (ATM)
"data_structure_type": 5 is now 6
and "pm_10p0_???? references are now "pm_10_????
Edit: My code now works with both versions.
Now live data (http://www.beteljuice.co.uk/betel_AQ/davis_example2.php?AQtype=US)
-
I guess I should find a way to upgrade the firmware on my Airlink. On the other hand, it seems the old and new data format end up having the same content.
Thank you for so quickly updating the reading code.
We mostly stayed indoors today, although the air quality at our altitude (~700m = 2200 ft) was tolerable; in the US AQI system it was 150...160 most of the day (PM2.5 seems to have been around 130 ug/m3). Given the proximity to some very large fires in California (we were actually evacuated for a week, with the fire 5 miles = 8km from us), he air quality has been much worse recently.
-
Mine is out for delivery.
-
Ordered mine this week hoping it ships soon. Im on the east side of ca and the last 2-3 weeks have been brutal with smoke! Becoming an aq expert now! Does this have the ability to calibrate or apply a factor to the values its reporting? I saw the purple air units can do this but didnt see anything mentioned in the manual
-
Like most sensors on the market now, it supplies avg 'ATM' figures apart from _last (20s) reading.
Everyone should note, the ATM compensation is based on only one University study and is now seriously questioned as normal ambient air content and the season all affect the readings. (Apparently the Uni site has high salt content in its air)
-
For those of you who have received the unit or have verified, how long is the power cord that comes with the unit? I am trying to figure out my plug setup with having to use their USB cord adapter on something meant for outdoor installation. I really can't believe they couldn't have come up with a better power cable solution than they did with this. I am thinking about one of those combo USB receptacles in a weatherproof box from which the cable can be directly plugged in without the need to use a USB to AC adapter.
-
Somewhat inaccurately: 6'6", or about 190cm. If you need it more accurate, let me know, and I'll disconnect it and stretch it out along a tape measure. Before winter, I'll have to do something about both the power supply cable and the general rain shielding of the module.
-
Thanks. That’s what I was looking for. I had a hunch of roughly 6 feet since that seems to be the standard cable length. No need to disconnect it to measure it out.
-
Is this different than the current Airlink?
https://www.davisinstruments.com/product/airlink-professional-air-quality-sensor/
I just ordered that, very excited to play with it and be able to put a number on the horrible air here in northern california.
Although this system has been working pretty well:

Yes, we do. You'll need to email sales@weatherstations.co.uk with your exact shipping address please (so we can price the shipping) and with payment via Paypal or bank transfer and someone will send through a quote.
As yet, we only have UK style mains adapter but the cable has a USB plug to the adapter and so any comparable decent quality USB charger ought to suffice.
-
Has anyone come up with a scheme to power this sensor outdoors? I don't know why Davis didn't consider a better power solution for outdoor placement.
I see some "Solar USB Chargers" on Amazon, some with a mounting bracket that look like it might work.
I am concerned about how these would hold up over time and whether they have enough mA-hours to actually power the sensor properly.
I might consider one of these if there was a good power solution for outdoor placement.

Depends what you mean by 'outdoors'. Couple of scenarios:
1. Close by a house or office where a mains-derived DC supply could still reach. My best guess for this at present is eg a 5m extension cable for the DC jack, but you'd need to ensure that the cable joint was indoors.
2. Remote from any likely AC supply: I'd guess that a 6612 Solar PSU would work (6v @ 50-100mA seems to be the likely current draw), but I think that Davis are seeking to validate this. It's rather an expensive PSU option though. Remember that the DC supply is USB type at the adapter end (but DC jack at the AL sensor, ie like a console) so any solar USB power pack could work in principle, but getting a powerful enough rating for 24/7/365 use could be the challenge.
Remember also that this is a WiFi device with no demountable antenna so always needs to be in WiFi range.

I would prefer Option 2. I don't want to run mains power for it.
I am well within WiFi range.

Since I have PVC conduit running underground to the post holding my Davis ISS and PurpleAir sensor. I cut the PurpleAir power adapter cord midway and spliced in 25 feet of 18 gauge wire. So the AC adapter is plugged into a GFCI in the garage.
Dennis
-
If you have an existing outdoor plug, you can buy an extension cord and cut the female end of it off and wire it to a GFI unit inside a weatherproof box with a weatherproof cover. Wire up the cut extension cord as your line input to the GFI. Plug in the extension cord to your existing outside plug. Plug the AirLink into the GFI outlet. Alternatively, if you didn't want to use a GFI, you could put in one of the USB outlets and skip using the AC adapter since the USB end would plug into the duplex. I am opting for the GFI and if there are issues with the adapter, which I don't think there will be, I will resort to option 2.
-
Just got mine yesterday and have outside in a temporary location til I figure out what i want for power at the permanent location. The unit is really quiet! Just ordered another for indoor duties. Easy setup and fast. Seems to be inline with other purple air units and the one official monitor.
-
My original idea was to mount this inside of my Novalynx thermometer shelter. This is on the opposite side of my deck from the closest power outlet.
If I mount the AQ sensor on the side nearest this outlet, I could power it from there.
Is there any sensitivity to temperature/sunlight?
I can somewhat shield it from direct sunlight during early morning and in the afternoon it would be in the shade in this location. Not as good as the shelter, but it might be OK.
Greg H.
-
As far as I'm aware, the main issue re shielding and outside use is with T/H readings so that's the aspect to bear in mind. I believe that any effect on the AQ readings is minor, but at the same time obviously not a good idea to mount it exposed to the midday sun for several hours.

I have an issue with the IP address assignment - every one day or so the sensor decides to take another IP address despite I've set it to a fixed assignment in my DHCP server. Anyone experienced this issue?
-
I just sinatlled mine, I got lucky that I have a cover patio with electrical sockets every where for this purpose.
I will post pic soon, but for now, AirLink and Purple Air only deviate by .1 PM, very impressive!
Note: I installed the AirLink in the opposite side of the Purple Link for the sakes of testing data accuracy.
-
I see that the map at weatherlink.com now has a separately-selectable overlay for Air Quality.

yeah though its a pity you cannot view indoor airlinks on the map even though they are set to public. On PurpleAir map any indoor ones are set with a black circle around them just to identify the indoor ones.
looks like we have about 15 or so in the UK now. [tup]

I've received one of these last friday. I'm a bit concerned by the variability of its readings. I have two sensors right next to each other in the same room (conservatory). The Davis Airlink and a Nova SDS011. Here's a graph of the last 24-hours of the two sensors:
[ You are not allowed to view attachments ]
The Airlink is often reading much lower than the SDS011. It also has the tendency to read zero values (< 0.01 microgrammes/M3) when the SDS011 is reading ~1.5 & ~2.5 on PM2.5 and PM10 values respectively. My air is good (at present; see: https://aqicn.org/station/united-kingdom/basingstoke-and-deane/ibasings39/) but it's not totally devoid of particles.
How reliable do we think the Airlink really is?
-
I don't have any other sensors to compare to. However, when I register zero or close to, both PM 10 and 2.5, it ties in with the UK emissions maps.
PM2.5

I've got all values and AQI's updating every 1 minute on my site if you want to compare at any time.

Interesting chart - what's the source website as I'd like to compare my own in the same way.
I also like your template and the AQI in particular - https://warehamwx.co.uk/air_quality.php. Are you able to share the source code for this page?

Drop beteljuice a message. He should be able to sort you out. :-)

Well, im waiting for mine!
Is this airlink send data to another weather system?
-
So, when using the local API on the airlink, I notice that the field 'last_report_time' updates on each call. It even seems like it updates every second, or at least every 2 or 3 seconds. I also notice that the 'pm_x_last' field, which represents the last reading made by the Airlink, changes slightly on most calls.
The question, how often does the Airlink do a reading that you would potentially want to retrieve? I currently have the readout interval at 15 seconds. I don't think I would want to go much lower in any case, but still interesting question.
-
I made a Python script to test this and found that it updates its readings once a minute. It updates it's averaged out values more often that that though, but I wasn't concerned with those so I didn't try to figure out how often.
Here's the script in case anyone wants to confirm:
#!/usr/bin/python
'''
This tests the update frequency of the Airlink. It shows the seconds since change and keeps
track of the fastest responses.
Conclusion: For pm_2p5, it updates once a minute
'''
import aqi # pip install python-aqi
import requests
import time
# IP of the AirLink
ip = "10.10.10.51"
previous_pm_2p5=None
last_update=None
shortest_update_time=99999
print ("Querying the Airlink at %s once a second..." % ip)
while True:
try:
response = requests.get("http://%s/v1/current_conditions" % ip)
data = response.json()
conditions = data["data"]["conditions"][0]
pm_2p5=conditions["pm_2p5"]
if previous_pm_2p5 and pm_2p5 != previous_pm_2p5:
if last_update:
p = round(time.time() - last_update)
if p < shortest_update_time: shortest_update_time=p
print "Data changed to %s after %s seconds. Shortest update time is now %s" % (pm_2p5, p, shortest_update_time)
last_update=time.time()
previous_pm_2p5=pm_2p5
except Exception as e:
print ("Error processing: %s" % e)
time.sleep(1)
continue
time.sleep(1)
-
Conclusion: For pm_2p5, it updates once a minute
I might be better to target those values, rather than the 'x_last' fields, since they seem to update so fast you'd be missing a lot of data in the mean time unless you'd persist it every 2 or 3 seconds.
-
not sure I understand, but I wasn't targeting the x_last fields, I was retrieving the pm_2p5 value from the AirLink.
My test scripts requests pm_2p5 twice a second and records when it changes. It never changes more than once a minute.
I do use some variables with "last" in their names internally in my script to keep track of previous readings, but those aren't the AirLink variables.
Edit: I just edited my script to change it's internal variable names to avoid confusion with the Airlink variable names.
-
not sure I understand, but I wasn't targeting the x_last fields, I was retrieving the pm_2p5 value from the AirLink.
I was just referring to my current readout setup, where I query the Airlink every 15 seconds and retrieve all x_last fields. It probably makes more sense to do what your script does, read the 1-minute average.
-
Aha, I didn't realize that was a 1 minute average. I just had it poll pm_2p5_last with a .5 second delay between queries and it updates once a second.
-
I find it a tough call to decide what data to work with. It seems that the readings pretty much update every second and also change at that speed. That is too frequent to readouts of all the updates. If you decide to pick the 1 minute averages, you get a representation of all readings, but you end up with a summary rather than a real time readout. Additionally, the temperature and humidity are always real time, so they don't strictly line up with the pm data being saved. Though that may be splitting hairs, I prefer to have real time readings as to work with as raw data. Does anyone have thoughts one the matter? What are conventions as to the proper way of reading this type of data?
-
Oof, can't say the AirLink readings are boring. Values going much higher than I expected. We live in a (relatively) rural area. But there is a big incinerator about 7 kilometers to the South West. Can't help but notice that when the values started dropping this morning, winds were also changing from SW to W. Way too early to say anything, but I'm definitely going to have fun making sense of the readings in the future!

Very nice chart. What are you using to build it? Or does that come with the "pro" subscription?
Agreed about the winds, I'm right on the ocean in northern california, with fires nearby. When the winds shift the aqi changes dramatically. I really need to figure out how to add wind speed and direction to my chart, which is here:

I added the PM values to the dashboard of my website. https://meteodrenthe.nl
Found that the yearly average for my location is around 15 µg/m³. Haven't yet found any maps that are useful to compare my values with. Is there a map with good coverage (for NW Europe) out there?

I’m still waiting for a working unit. I received mine last Friday from Scaled and it doesn’t work. It powers and connects to the Internet fine, but will not pull data. Davis confirms that if I don’t hear a fan running that it is bad. They are going to send me a replacement unit directly. They won’t, however, foot for return shipping of the DOA unit I received. Scaled also does not appear to want to assist with covering it, which, frankly, I am a bit taken back and not happy with.
-
Strange, I don't hear a fan running in mine, and it's working... Assuming you're talking about an AirLink.
-
Yes. There is a tiny fan that is supposed to run when it is operating. That is what Davis’ tech support said. He said if its not pulling data and can’t hear a fan it’s likely defective. I know it’s connected to my wifi fine and I deleted it and set it up twice and have done multiple checks with the WiFi in the WeatherLink app and it doesn’t display data but is connected to the Internet.
-
My Airlink is two days in operation at my house. I had not noticed the fan, but after reading these posts I held it right up to my ear in a quiet place and did hear it.
-
Aha, me too, hadn't noticed the fan previously either.
-
What are folks using for the power supply for outdoors use. The reason I ask is that I have a water resistant cover, however, the plug sticks out too much. I almost need a smaller AC to USB brick at a right angle for it to fit properly.
Wondering if anyone has any good ideas before I reach out to Davis. I'll have to post some pics soon.

Your best bet is to buy a 5V DC extension cable - available up to 20m. Either put the join of the AirLink cable indoors, or route it through a small - cheap junction box.

So all of my Airlink values show up on the Weather Link website just fine, however when I set everything up in Cumulus Mx I get nothing, has anyone else had difficulty or have some advice to get me running?

Do you have a subscription to Davis? If not, make sure you haven't filled in any of the API boxes.
-
I only have the free basic plan, so should I remove my API key and secret?
-
Yep - Not needed.
Check Enable Outdoor AirLink
Check This AirLink has been added as Node to another station
That should be all you need.
-
Any other thoughts? I do not have to have a Weather Link Live system or should it work with the old Weather Link that plugs into the back of the console, correct?
-
Weather Link Live is irrelevant. The AirLink is a standalone device which CMX will pick up. You may need to restart CMX..
-
I have one AirLink and two separate CumulusMX installs:
One using WiFiLogger and have Extra sensor settings Davis Airlink;
API key entered
API secret entered
Outdoor Airlink enabled
IP address entered (AirLink IP address)
Station ID entered
Air quality index specified.
This works fine.
The other using the WeatherLink Live and have Extra settings Davis Airlink;
API key and secret not enabled
Outdoor Airlink enabled
IP address entered (AirLink IP address)
Station ID entered
Air quality index specified.
This also works fine.
I am still working on how to display the data, and the CumulusMX WLL is at http://www.komokaweather.com/cumulusmxwll/index.html (http://www.komokaweather.com/cumulusmxwll/index.html) select Misc. AirQuality

I have got my Air Link and I am figuring out getting power for the unit.
The cable is rather short for me to reach the power I can access. I was thinking of using a DC extension cable, though I haven't been able to find any cable here in Australia that would has the small plug for the power jack. I can get a extension cable easily for a 2.1 mm or 2.5 mm pin, but not a cable with a smaller pin.
I suppose I could instead extend the USB end of the cable instead.
Any idea please?

I was looking at using a solar panel into a solar controller with USB, connected to a 7.5Ah battery. Got all the kit, just need to find the time to put it together and test it. Worried about the amount of sun we get here in the winter.

Ah OK, you want to query your AirLink data outside of your local network.
Well, mcrossley posted something, maybe that works.
Otherwise you could consider opening an external port on your router and point it towards your Airlink so you can query it from the net. But I guess going that direction is always a bit iffy.

Thanks Mark, im trying too hard!, but i dont get it.
I have API Key v2 and API Secret, i made a HMAC Generator but i have a doubt with use of t (which timestamp i need to use?)

"t" is the current time in Unix integer format. It has to be within 5 minutes of the current time for the API servers to accept your request.

That timestamp equates to 2020-12-19T06:24:38, so your Unix time generation code is way off, if you generated it around 00:45 when you posted the message. Unix time always uses UTC.
This is all really a separate topic and should be on a new thread.

I ended up using a USB extension cable similar to that one. It seems to work fine with the Airlink. I didn't check whether I get any voltage drop but I am using a 3 m extension lead which keeps the total USB cable length to not exceed the 5m limit in the USB2 official spec. My has AWG24 cable rather than thinner cables of some the USB cables on the market, so that probably helped with minimizing the voltage drop.

Do you guys recommend using the screen when installing outside?
Have you found any accuracy impact from the screen?
Moving my air link outside tomorrow now that I have power run to the location so trying to decide screen or no screen.

I used the screen outside on my porch since a lot of rain blows up there, and I didn't want any issues. I haven't been able to tell if it impacts accuracy.

Does anyone know the update interval of the AirLink data in the Weatherlink.com bulletin (standalone AirLink)?
I have the Pro subscription and the 'Last updated' timestamp changes every minute, but it is hard to tell if the data values actually change that often. The historical records are stored in 15 min intervals.
Considering downgrading to a Basic subscription, but would like to know if the upload interval is the same. There is a parameter in the description of the various subscription tiers called '3rd Party Intervals', which is 15 min and 5 min respectively for the Basic and Pro tiers. I don't think it applies to the Weatherlink site though, only to uploads to 3rd party sites.
Also, does anyone know how much data can Airlink buffer if it loses WiFi connection? I noticed it remembers data and sends it up once WiFi is restored.
Thanks!

Airlink updates at 1 minute intervals. I grab the data via Cumulus MX, and show the values on my website. They update every 1 minute regardless of a subscription, because the Airlink is a standalone device.
I use a Weatherlink Live, and I'm pretty sure data is sent every 1 minute even without a subscription. You'll only see updates at 15 minute intervals, though.
As for the buffer size - not sure. I was offline for around 3 to 4 hours when my fibre internet was installed, and it sent all of that missing data through to Weatherlink once I was back online.
-
Using Cumulus MX you might be able to get the data at 1 min intervals, but the WeatherLink app has handcuffed all three of my AirLinks to 15 min intervals since I don’t have Plus. Trying to see if I can get a free copy of Plus since I work for AEM, but if not, I may just spring for it myself since I need to try Mobilize.

I'm pretty sure that Airlink data in the Weatherlink app updates every one minute, even without a pro subscription.. Perhaps you mean the archive interval?

Yeah. There are four separate time intervals involved with AirLink and WeatherLink.com:
1. Interval at which AirLink sends data to Weatherlink.com servers. This is 1 minute as stated in the specs and confirmed by experiments.
2. Interval at which the bulletin page on Weatherlink.com displays fresh data from Airlink. According to @Mapantz 's post above, this also is 1 minute, regardless of the subscription tier. This was my original question.
3. Historical data storage and charting interval. This is obviously 15 minutes regardless of tier.
4. Retransmit interval by weatherlink.com to 3rd party sites. This is tier dependent - 15 minutes for Basic, 5 minutes for Pro and up to 1 minute for higher tiers.
-
I just re-checked and it is archive rate. Seems you can bump it up with Pro, but otherwise it does send data to the dashboard every minute. Good to know!
-
3. Historical data storage and charting interval. This is obviously 15 minutes regardless of tier.
I have Pro+ and can set AirLink archive rate to, 1 min, 5 min, 15 min, 30 min, 60 min
-

I stand corrected. According to the WeatherLink app, I can bump it to 5min with Pro, but it requires Pro+ for 1min. 15min and longer for Basic.
Apparently, you have to use the App to change the archive interval, I have not found any setting for it on weatherlink.com.
-
I have also found an answer to my question about the buffer size in the AirLink. Onboard data storage depends on the Archive interval:
1min - 21 hours
5 min - 84 hours
15 min - 100 hours
30 minute - 130 hours
60 minutes - 268 hours
120 minutes - WeatherLink crashes, apparently an invalid archive interval option
-
Apparently, you have to use the App to change the archive interval, I have not found any setting for it on weatherlink.com.
Weatherlink.com- under Device Settings for your Airlink is the Archive Rate.

Yeah, WeatherLink.com is a little clunky to navigate. If anyone has any feedback on it, let me know, and I can pass it on to their teams. What they do with it we’ll see, but at least I can try!

I've had an Airlink for about two years and up to about 3 months ago, it worked fine. it is mounted outside, but sheltered from rain, etc. About 3 months ago, it would occasionally stop reporting (I would receive a message from Davis that it had stopped). If I did a reset, it would start working again. At first this only happened about once a month, but about 2 weeks ago, it began to happen daily. At first, I thought that possibly it was not receiving a good Wi-Fi signal, so I remounted it, but that did not help. I also tried switching out the USB power supply, but that did not help. When I checked my router, the unit was sometimes not shown as connected to the network and sometimes as connected even when no data was going to Davis. Lately, it has started working again.
I contacted Davis support and got a generic "it has failed" messaged and to contact them about replacing the unit.
Now that this unit has been around for awhile, I am curious if anyone has had any issues. I am also curious if anyone has disassembled the unit and if something like moisture intrusion could be an issue and if cleaning is feasible or helpful.
I went through the standard setup using DHCP on the network. I can't recall if there is an option for a fixed IP address, which may or may not help.
-
I've had one since early Jan 2021 - no issues so far.
I have taken the case apart to get at the optional filter, but never looked at taking the sensor module apart, but I think there are teardowns of it "out there".
-
Thanks for the quick answer. I have done searches looking for information on the innards of the device, but not much has popped up.
-
I’ve had three of them installed at my house for a couple of years now. So far, none of mine have failed. Occasionally the readings have been a little off if my Internet glitched (a simple reboot seems to correct the issue), and occasionally I’ve dusted off the sensor to ensure it’s working.
-
My Internet connections are generally quite stable. My Davis Vantage Pro 2 makes a hard-wired Ethernet connection to my LAN using a Davis WeatherLinkIP data logger configured with a fixed IP address. Every so often (maybe once or twice a year), the data logger green LED stops blinking and goes solid, indicating data is not currently transmitting. When that happens, I do a power reset and it starts working again. Generally, no data are lost and it all gets reported to the NWS. But that has no relationship to the Airlink, which makes its own direct Internet connection through my wireless network.
Does anyone know if you can use a fixed IP address with the Airlink? Sometimes that provides a more stable connection that DHCP.
-
I did a DHCP reserve on my router (Ubiquiti Dream Machine Pro) for all three AirLinks just to ensure it gets the same IP address each time. I haven’t looked to see if I can hard-code a static IP into the AirLinks themselves since DHCP reserve works really well on my UDM Pro.

I went ahead and reserved the IP address in my router for my Airlink. It probably won't solve my problem, but it is probably a good idea.

I just run with reservations on nearly all my kit, including the AirLink.

Now that this unit has been around for awhile, I am curious if anyone has had any issues. I am also curious if anyone has disassembled the unit and if something like moisture intrusion could be an issue and if cleaning is feasible or helpful.
I've had issues with two units now in about 2 years. Both times the blue light would stop coming on. It won't connect to wifi, etc. The fan of course still spins up.

I got my Airlink working again by moving it closer to my Wi-Fi antenna. Previously, it was about 30 feet from a garage which housed the main router and its Wi-Fi antenna. I moved the Airlink to an outside wall of the garage, where it is about 10 feet from the antenna and next to a window. This seemed to fix the problem. It has been working correctly for a couple of months. I liked my prior location better as I thought it was more representative of air quality conditions. If I get ambitious, I might put up an outside Wi-Fi antenna and move the Airlink back to the original location. I am guessing that the Airlink may not have a great receiver as well as being very sensitive to interference. My unit was just on the margin of working correctly previously.
