Hello to all users and visitors of the WXforum forum. I open this new thread to discuss with you about the Tempest weather station from the American company WeatherFlow. I received the station a few days ago and I am already creating the first comparison graphs with the stations I own, that is a gw1003, composed of the ecowitt WS80 station, the WH40 rain gauge and a WH32-EP sensor in Barani Pro sunscreen. installed a manual rain gauge to be sure of the readings of the devices.
I am attaching photos of the installation.

As already said I started building the first graphs and these are the results:

to simplify things and avoid messages, perhaps it is better if I send the discount code directly. It is this: COMPARETTOIVAN
The only shrewdness and suggestion I give you is to copy it by reading the message in the original language avoiding corrections or modifications by the translator.

About IFTTT, I connected the station to IFTTT in order to create automatisms, such as the one that allows you to transcribe data every 1 minute on a google sheet up to a maximum of 2000 rows per sheet, which will be replaced by a new sheet when it exceeds 2000 lines. Furthermore there is the possibility to create a google sheet with all the data on lightning, etc.
I attach some screens

Hi Ivan,
you are aware that this offer is - as per the Weatherflow website - only available in the U.S. and in Canada so far.
[ You are not allowed to view attachments ]
-
also, quite some people report that the so-called haptic rain sensor generates a lot of false positives.
Because it is sensitive to vibrations. It translates the vibration that a hitting raindrop causes into a rain measurement.
In principle an interesting idea.
However, e.g. Jets/airplanes flying over the mounting location but also other vibrations are interpreted as rain.
Did you do already some measurement regarding the haptic rain sensor ?
Or is the weather too sunny these day ? 8-)

I seem to have said this in some previous post, however yes, at the moment it is only available in the states you mentioned

I still can't say anything about the haptic rain sensor, very sunny days, very hot but no precipitation in the previous days and not even in the next few days. When it rains I will publish the results here.
I too had heard of these problems, but I think they were more present in the 1st version of the station, I think that with the Tempest sensor the situation has improved a little.

that should be verified before the purchase as the station not cheap - around 330 USD before state tax - and importing into the EU means + VAT (19-30% depending on member state) + custom duty for items > 150 EUR

For the shipment to Italy from America I paid 90 € of customs duties, if you wait for the moment when they will sell it in Europe you will save these 90 € of duties, which are not few. It shouldn't take long for availability in europe!
-
when the haptic rain sensor issue is sorted out, it could be an option - even though it's again a 7-in-1 array.
But I have helicopters and air planes with noticeable sound flying over my place - one of the reasons for the false positive readings.
In one finding a fighter jet caused 32 mm of (non-existing) rain reading.

WeatherFlow's main office is located next to Daytona Beach International Airport and the Daytona International Speedway. They used to have dozens of test stations on the roof, and I would check them out on race weekends and other times to see if they picked up any false rain. There was no noticeable sound triggers that I ever noticed, from planes, 43 open-header NASCAR engines, 10,000+ Harleys in town for Bike Week, fireworks, etc.
My own Sky/Tempest stations are located under the final approach to an international airport, which hosts the NY Air Show every summer. I only saw ONE false rain trigger, over several years and multiple practice days for the USAF Thunderbirds, Blue Angels, and RAF Red Arrows. Not even a little "oopsie" sonic boom that rattled our neighborhood set off the rain sensor.

(https://images.hvtraffic.com/images/2018/09/25/20180925175426-7f4f80bf.png)
That being said, I still consider the haptic sensor to be questionable at times, and have a 4-inch Stratus manual gauge and several tippers for measuring rain.....

Thanks for the excellent info you gave, I certainly won't have the opportunity to test all this, every now and then some helicopters pass by but nothing more.
As you say, surely there will be improvement, but I believe that by now it will be the technology used to measure the rain in the future !!
@Gyvate. In my opinion there is also to consider how stable the pole in which the station is positioned is, that is, if it is not very stable it could also be the vibrations of the pole that affect the station to cause the false readings, I think.
For the speech of the station which is all in one, consider that other more professional brands have also adopted the all in one sensors, I refer to the Vaisala in detail.
(https://www.eurowebcamsite.com/images/Stazioni%20WDS5/Vaisala.jpg)
Of course, and I agree with you on this, having separate sensors allows you to position the various sensors in the best position respecting the rules as much as possible, but with all-in-one groups you have to make choices, in my case I tried to position the rain gauge and the temperature sensor following the rules, but at the expense of the wind sensor.

how do you explain these break-ins of solar radiation of the Tempest when the WS80 doesn't show a break-in and later on vice versa ?
Is there a sun position at some time of the day where there is some obstacle (tower, tree) which throws a shadow on the sensor ?
And the shadow of the same obstacle hits the other sensor two hours later ?
-
I can easily answer that it is the pole behind the station (tempest) which causes that lowering of the radiation, which then affects the ws80 after a few minutes due to the rear pole. So sw there were no poles there would be no such problems

As you can see, the performance of the Weatherflow brand Tempest station is really excellent. The graphics are really good, performance in my opinion very, very good. I would say that these graphs already delineate very precisely the performance of the station, all that remains is to see the performance of the haptic rain sensor. After all, I'm really really satisfied !!
I always remember that you can use, for those interested in buying, the COMPARETTOIVAN discount code that allows you to get a 10% discount on your purchase. Better than this!!

Definitely surprises me that the shield apparently works so well. Would not have expected that looking at it. Would you say that it appears that the sensor in the Barani shield seems slightly more responsive?
What happens if any part should ever break down? Are there replacement parts?

Perhaps a little more reactive is the barani, but not much. This also affects the probe inside, which is not really very small. The other comparisons that have been made previously gave different results, but in that case the probes used were PT100 probes which have even smaller dimensions!!
The probe I use is this:
(https://m.media-amazon.com/images/I/51LPj5yAefL._AC_SX425_.jpg)
While the PT100 is this or such probes:
(https://data.polsinelli.it/imgprodotto/sonda-pt100-3-fili_5049_zoom.jpg)
The size and performance also vary greatly
For the spare parts I can't tell you: at the moment on sale as spare parts there are only the hub to fix the station to the pole (https://shop.weatherflow.com/collections/accessories/products/pole-mount-replacement?ref = IvanComparetto) and the spare power supply for the hub (https://shop.weatherflow.com/collections/accessories/products/power-supply?ref=IvanComparetto).
I'll find out more about it this afternoon.

I inquired about spare parts:
We don't sell spare parts for the Tempest at this time, so usually if something fails we replace the whole unit.
The replacement of the station can take place in the following ways:
The money back guarantee, where you can return your station for a refund, is 60 days. There are another a 2-year warranty and 10-year limited warranty: (applied automatically with every purchase)
- Two (2) Year Warranty - If the Device is or becomes inoperative as a result of a manufacturing defect within two (2) years from the date of purchase, we will replace it with a comparable replacement product at no cost. This includes Device failure due to defect but does not include failure due to misuse in unintended ways, abuse such as dropping the Device, natural causes including lightning strike, or unnatural causes such as vandalism.
- Ten (10) Year Limited Warranty - If a Device is or becomes inoperative as a result of a manufacturing defect outside of the Two Year Warranty period but less than ten (10) years from the date of purchase, WeatherFlow offers a 60% discount off manufacturer suggested retail price (MSRP) on a replacement Device.
Feel free to visit our Warranty & Hardware Terms of Use support page https://help.weatherflow.com/hc/en-us/articles/360055890614-Product-Limited-Warranty

Hello everybody. I update by communicating the possibility of connecting the Tempest station to the WeatherWizz dashboard. It in a single screen allows you to see most of the values detected by the station (not all) but I believe that as they are implemented, perhaps to see them you need a small monthly donation to support the site. It could be a valid alternative to view data on a tablet (it was born for this purpose).
To connect the station just press the "connect weather station" button, press "setup tempest", press the "connect weather station" button and at this point you will be redirected to the site of the tempest station, just enter the site and the station is all ' interface.
Here is the link of the site: https://www.weatherwizz.com/ and this is the link where you find my station connected: https://www.weatherwizz.com/ew0001dt/?station=XIEVUHQWIV
p.s. there is still something to fix but it works !!
Here is an example of the dashboard:

I update by communicating that a tailor-made dashboard has been created for the Tempest station. In it, all the values detected / calculated by the station can be displayed. In order to take advantage of this dashboard, you must support WeatherWizz on patreon, with a monthly payment of € 3.50 + VAT.
Also added in the dashboard the voltage of the station, so that you can have a detailed picture of the station.
If you have any suggestions or ideas to give, go ahead, I am available, I will also reply to MP if you want !!
This is the "updated" dashboard:

This Patreon membership for weatherwizz.com is normally ONLY necessary, when you want to rename your sensors.
All other "templates" are free.
Except for the Tempest station (direct connect).
For all Stations with Ecowitt, Ambient, WU protocol using the custom server function or connecting to weatherwizz.com via Meteobridge, weewx, Weather Display, CumulusMX the templates are free and even a Tempest connecting via MB, weewx, WD doesn't need to use the special Tempest template.
Anyhow, at least outside the U.S. and Canada, the Tempest isn't sold (yet) ...
Except for some people who took part in a Crowd-Funding activity for the Tempest station, no one in Europe probably has it - it would anyhow be unlawful to operate the U.S. version transmitting at 915 MHz.

Perfect what you said. But I don't know if connecting the Tempest station with MB, weewx, WD, the values such as DELTA T, air density and other similar values, which most of the entry level do not detect, without supporting Patreon, are displayed in a dashboard, I think not, at most the main values are displayed such as temperature, humidity, pressure, dew point, lightning and rain and a few others that escape me at the moment.
On the question of frequency I don't know how to answer you, they sent the tempest station to me in Europe, and they did it to someone else too, but I don't think it is at 915mHz, maybe they have found a system that allows them to create only one type with frequency interchangeable or have 3 types with different frequency. I do not know.

Goodmorning everyone. Yesterday morning some very small shower of rain in the stations of Alia.
Rain which led to an accumulation of 0.3mm for the TEMPEST station (rain duration 33 minutes) while 0.1mm for the ecowitt WH40 sensor. We will wait for better days to draw conclusions !!
So these are the graphs:
As can be seen from this screen accumulated 0.3mm:

While the PT100 is this or such probes:
This is slightly off topic, but I've been looking at a PT100 for testing. Do you have a link to the exact probe you've been using? A lot of the options seem to be designed for very high temperature environments.

The one in the photo is an example, I use the normal plastic probe, that of the WH32-EP sensor. I do not know a suitable probe, I have never used this type and I would not be able to recommend a suitable probe !!

I update the post by communicating an update made to the WeatherWizz dashboard. A new feature has been implemented that allows you to view on the dashboard itself as well as the battery voltage also the mode in which the station works.
Let me explain better, if the station is below certain voltage values, some parameters will not be detected to help recharge the battery, as illustrated below:
- Mode 0: voltage ≥ 2.455
• All sensors are enabled and operating at peak performance
- Mode 1: voltage ≤ 2.415 from mode 0 or ≥ 2.41 from mode 2
• Wind sampling interval set to 6 seconds
- Mode 2: voltage ≤ 2.39 from mode 1 or ≥ 2.375 from mode 3
• Wind sampling interval set to one minute
- Mode 3: voltage ≤ 2.355
• Wind sampling set to 5 minutes
• The sampling interval of all other sensors is set to 5 minutes
• Lightning sensor disabled
• Rain touch sensor disabled
Then in the dashboard now next to the battery voltage value, also check the mode in which the station is working and if in the case of mode 3 the values that are not detected are colored red, therefore very practical to view.

Charts for today, 30-8-2021:
- TEMPERATURE OF THE BARANI PRO - TEMPERATURE TEMPEST and WS80: today the behavior of the ws80 opposite to that of yesterday, yesterday it was mostly below the barani, instead today it is on average above. The storm, on the other hand, is always under the barani in my position, while it goes above the barani in correspondence with the sudden lowering of the radiation caused by the pole behind the station that "shadows" it in those minutes, and from then on also because of the reduction of solar radiation probably the correction will be disabled.

Graphs for YESTERDAY, 04-09-2021:
- TEMPERATURE OF THE BARANI PRO - TEMPERATURE TEMPEST and WS80: very strange graphs yesterday. As suggested by Mauro, I raised the probe by positioning it between the 5th and 6th helicoid, instead of between the 3rd and 4th as recommended by Barani, around 10 am! From the graphs it can be seen that the other screens have detected lower temperatures than the barani while the songs higher, this in the period between 10:35 - 12:15 then the situation is more aligned. For the rest we are as in the past few days. As you can see there are serious data gaps, caused by the power failure there at the station, and therefore the data of that time interval has been completely lost, a real shame. In that interval there was the highlight of today's rain. Thinking about it before, if I had put a powerbank in the tempest I would not have lost the data in that interval as it has a system that allows it to save them momentarily and as soon as there is current again it loads them online, different speech for the ecowitt, I could not do nothing!!

I am attaching a video of the rainfall around 8:00 am in the village, you can see that it was very intense: https://drive.google.com/file/d/1oc...iew?usp=sharing
Before midnight other precipitation: Tempest station until about 10:35 had recorded an accumulation of 12.1mm, which in the minutes before midnight reached 13.8mm, therefore an increase of + 1.7mm.
For the WH40 rain gauge, on the other hand, we had an accumulation of 3.4mm which reached 5mm before midnight, therefore an increase of + 1.6mm, in line with the Tempest station.
The manual, on the other hand, yesterday morning had an accumulation of 15mm, he did not lose any data !!!, while between yesterday night and today's morning I notice an accumulation of about 2mm, I look at it from the camera so it is not really easy to distinguish the accumulation, but there we are!
(http://www.lineameteo.it/files/images/3051/b2ba4b25_c826_48aa_965f_9f6273b57844.jpeg)
Today, however, the storm did not detect any mm of rain, while the ecowitt detected 1mm at 3:00 in the morning while another 1mm at 6:50. Looking at the videos that I have saved all night I don't see any precipitation, so it may be condensation, also because the humidity was on values of 96-97%, therefore very likely

Precipitation today of 2.2mm for the storm while 0.3mm for the ecowitt. The situation is very strange to me as the station detected rain even in moments when it really did not rain but there was very strong wind in those moments, I would not want the wind to influence the readings in my case, perhaps due to vibrations of the pole to which it is attached.
I attach a screen of those moments, in the other situations in which it rained, the ecowitt also detected it but to a lesser extent!

This afternoon, in view of the rains of the next few days, I thought of putting some tie rods on the pole of the storm so as to decrease the vibrations, in fact today going to the station I saw that actually some vibration was there when moving the pole, now it is much more stable, so from this point of view there should be no more problems.

Graphs of yesterday, 11-09-2021: from 12:00 onwards IFTTT has not saved more data in the google sheet, so in the graphs the data of the tempest are up to about 12. Too bad, it would have been interesting!
- TEMPERATURE OF THE BARANI PRO - TEMPERATURE TEMPEST and WS80: tempest good when there is data (on the tempest website there is no data, no wrong news must pass, on tempest there is no missing one while IFTTT does a bit of a tantrum ). WS80 in recent days suffers a lot in these conditions, from 7:30 to 12 always above the barani, from 12 to 13 it is slightly below, from 13 to 16 always above, around 16:20 it is below about -2.6 ° C compared to the barani, too many, then a little more aligned!

I got this idea: the Tempest station in my station has always suffered, since I installed it, from vibrations caused by not directly fixing the station to the main pole.
Let me explain: in my position I had to put an L-bracket fixed to the main pole, as the main poles were 4 meters high, and even if I would have put it on top of the pole I could not have done it directly as the pole is 40mm, while the station accepts poles up to 32mm (1 inch). Also in the bracket I had to do the same thing, as it is also 40mm and therefore I could not fix it directly to the bracket, but I had to put a 32mm plastic tube attached to the L-bracket.
So with all these additions of parts to the main pole I have lost the stiffness of the main pole; even putting some tie rods the thing has not improved that much.
Having said that, yesterday last day of testing, my friend came to get it and he will test it by comparing it with davis, he told me that he prefers not to publish all the graphs like I did, but he gave me the consent to publish the rainfall data that it will detect.

Good evening to all guys. These days the tests have continued normally, my friend has installed the Tempest station on the roof of the university so as to compare it with the davis pro 2 already on the roof.
The station, as you can see from the images, is installed on the low wall, fixed on a long wooden plank. He chose this position because by making various tests he noticed that, when the station is fixed by means of a support by means of a screw, even moving the axis in such a way the station did not report anything, while when we did some tests in the countryside by myself, before disassembling the station, punching almost imperceptible the station scored 0.1mm while punching harder the station scored up to 0.5mm.
So two different damaging systems mount different behaviors in this case.
Subsequently, the station will mount it on a pole so as to verify the behavior in person.
Here is the installation of the station: as you can see at the bottom of the terrace on the right the vp2 pro while the funnel near the station is a manual rain gauge.
(http://www.lineameteo.it/files/images/3051/dec022ad_6943_48e6_a558_0bf5130bef12.jpg)
As already mentioned, some parameters have not been taken into consideration, such as the maximum temperature, minimum humidity and wind due to incorrect installation, mainly addressed for the rain gauge test.
(http://www.lineameteo.it/files/images/3051/83012286_0e3b_4d1f_b4ff_bcee72805465.jpg)
The tests show that both the manual rain and the davis scored 0.8mm while the storm marked 1.6mm.
I add more info on resolution and diameter of the manual and details of the vp2:
- The manual has a diameter of 25 cm. Measurement resolution 0.1 mm. It is equipped with an evaporation inhibition system through the use of a known quantity, pre-weighed in the laboratory, of glycerin oil.
- The Davis Vantage Pro 2 rain gauge was laboratory calibrated on September 3, 2021 and will be recalibrated every 3 months. The funnel remained the original one. The single-chamber, on the other hand, made it possible to obtain accuracy values of up to 3%, a difference from the previous version which stopped at 8%.
- Davis is equipped with Sensirion SHT31, a new version anemometer with new bearings and single tank rain gauge.
-
Data as of yesterday, 9-28-21. The overestimates of the Tempest rain gauge continue, albeit on a smaller scale than the last event (slightly less than 50%, considering the 1.1mm of the manual as a reference). Davis marks 1mm instead of 1.1mm as it detects every 0.2mm. The rain shower was very short but intense.

It should rain again in the next few days, so more data will add to what we already have. After that, we'll send the data to weatherflow and see what they'll put in place as a calibration.
-
Here is the data for the month of September, with added the data of 30-9-21 with 0.8mm of the storm, davis 0.4mm while manual 0.5mm.
(http://www.lineameteo.it/files/images/3051/b59dadf3_a489_4214_88e0_3f902606f089.jpeg)
Day 01-10-2021 instead accumulations of 1.0mm for Davis while 2.5mm for Tempest (the manual could not verify this).
I update that with the data collected so far, to which today's data will be included, the weatherflow will apply a sensor calibration with an 8-point curve, since it has been noted that the difference between tempest and davis is incremental depending on the intensity.
This is a graph that shows just that.

I update the post, apologizing for not having done it before, with the rain data for the month of October.
(https://forum.meteonetwork.it/attachment.php?attachmentid=574555&d=1633551964)
Furthermore, news of a few days ago, the weatherflow has applied the 8-point calibration to the station, as previously explained. So now the station is running with the new calibration.
First accumulations after the new calibration. Now the opposite situation than before, now underestimates compared to Davis:
Tempest 4.6 mm.Davis 8.2 mm.
Contacted WeatherFlow again and now we are waiting for an answer. We'll see.
-
I add some data.
These are from day 7-10-21:
- Tempest: 4.6 mm - Davis: 8.2 mm - Manual: 8mm
These are from day 8-10-21
- Tempest: 17.7mm. - Davis VP2: 25mm.
These are from day 9-10-21 (today):
- Davis: 4.4mm
- Tempest: 4.6mm
The weather flow explained to us that the 8-point calibration, as in the case of pressure, takes place with an automatic algorithm and in a progressive manner. The improvement of the data compared to yesterday is linked to this. They told us that in a couple of days the data should be perfectly aligned. In fact today's data are almost identical, we will see in the coming days.
-
Good evening everyone. I update the post by communicating today's data (alas) for the moment partial until about 7 pm. Partial because a Davis datalogger cable has probably been disconnected and therefore the data from 7 pm are no longer loaded, tomorrow will solve the problem and we will communicate the data.
In recent days we discovered that the calibration had not been applied very well, seeing the data we see that some are "high" compared to the davis, we got in touch with the weatherflow, noticed that the calibration was not active and the reapplied on Monday morning.
What happened is not understood, our lack or incorrect application of them is not known, the important thing is the result, hoping that this new calibration goes well.
This is the table updated until 7pm today:

It looks like the humidity gets a little richer on the Tempest unit when the humidity gets above 85 percent. Tempest looks like it tracks pretty good to the Davis though.
I'm still kicking the idea around about getting one.
Thanks,

It will probably be due to the poor installation.
Sounds like a great idea to me.
I update with other data

Hi everyone, sorry for the absence in the discussion but I was too messed up.
So in the last few days my friend, with the weatheflow have worked hard to be able to obtain an accurate calibration even in that section where the station was detecting incorrect rainfall. After several attempts they have managed to get the right calibration and the latest data are encouraging and are much more aligned with the manual rain gauge.
For our part we did everything necessary to provide the data in the best possible way and they did theirs too.
However, the problem remains for those who will buy the station; to be sure of the data that it will detect, the station must make comparisons with other stations (or at least a manual rain gauge) in order to verify the calibration of the station. I understand that this can be a bit tedious and a bit complicated to do, but it is the only way to accept the correct calibration.
Having said that, I am attaching the latest data collected, the tests can now be considered completed.
October summary.

Good evening everyone. I publish the latest data collected: there have been great improvements, now the data between tempest and vp2 seem well aligned. These data:
23-11-2021: davis 0,6mm, storm 0,5mm
25-11-2021: davis 9.2mm, storm 9.2mm
(https://forum.meteonetwork.it/attachment.php?attachmentid=577507&d=1637962195)
The rain of 11/25/2021 was variable, at times weak, at times strong and at times very strong.
Tonight instead: davis 1,8mm while tempest 1,8mm; today's accumulation complete of 5,2mm for the davis while 4,8mm for the tempest
That's all for now.
I would add, for information, that in the weatherflow house they are working to create the booster that allows you to recharge the batteries in the station faster, a very useful accessory for users who do not have a day that allows them to fully recharge the batteries.

I just recently bought one of these stations and have been comparing it to two different stations. I am using a cut down sht31 in a Barani pro shield and a modified Davis 24 hr shield with a 31 inside. The modified shield has no fan and the bottom plate is a solid plate and the 24 hr core is replaced with a daytime fars plate that eliminates the sensor chamber and tubes so get passive air flow inside shield. Now the problems i have encountered with the wf station. A week or so back a strong cold front came in with winds of thirty mph plus gust and heavy rain, during this the wf readings went haywire with the wind direction moving around to the southeast and staying there and i was getting wind peaks of 50 to 70 mph. During this the rain fall was running higher than my eight inch tipping bucket and my eight inch manual gauge. After the rain i brought the wf station inside and found the plate below the sonic sensors was completely wet with bubbles of rain on it. I used a paper towel to absorb the drops, not supposed to rub the plate because it has a special coating on it, and when i returned it the readings were back to normal. Now the rain showed a little over a tenth too much. Now with a heavy rain and light winds the readings were within a hundreth of each other. The temperatures between the three have been doing real well except with cold nights and calm winds the pro and modified shield run a degree or so cooler than the wf shield, probably theromass of the two large shields compared to the small wf shield causing the lower reading. When the temperature at night didn't get low all three read the same. Another thing about the rain sensing of the wf station is i had a dad of misty, drizzley rain which turned out to be .08 inches for the day but the wf station showed no rain had fallen because it needs rain drops to record rain. Now today we had another strong front come in with high winds and heavy rain and i got the same results wrong wind direction and winds peaking at 50 to 60 mph. This time knowing about the rain drops on the bottom plate i just took a paper towel out to the shield and let it absorb the rain drops off the plates and that did it again, by the time i got back in the wind and direction were back to normal. So high wind and heavy rain mess up the readings on this station. Now before the front came in we got a heavy rain but light winds and the wf station showed .67 and the eight inch gauges both showed .68 so without the wind it was just fine and so far mostly it compares real well with the other two stations but does have some problems at times. The station uses the sht31 with the factory membrane. One thing i really like about the wf station is that in my area we get dense fog nearly eveynight this time of year and the larger shields get wet inside and this causes the humidity reading in the morning to take about an hour to get to the reading of the wf station which when the humidity is at 100% all night as soon as the fog starts to burn off the humidity starts to go down sometimes reading as much as 9% lower than the other two bigger shields. The high humidity is why i don't run my R.M. Young fars because of the large volume of air it pulls into the sensor chamber it takes a long time for the temperature and humidity readings to get where they should be. The wf is a nice little station but does have some major problems that would keep me from using it as a primary station.

Hi JerryG. First of all thanks for the post, also congratulations for the sensors and for the sunscreens you have. As for the problem you have encountered with the wind, this is the first time I hear that anyone has had this problem. Have you communicated this to weatherflow? What did they tell you if you communicated it. This seems to me personally very strange, I would not want it to be a defective product. As for the false readings of the rain with strong winds, I also noticed that they are overestimated compared to the comparison rain gauge, this is due in my opinion to the pole support which is very undersized compared to the size of the station, this therefore begins to vibrate slightly it is due to false readings, this in fact does not happen with light winds and in those cases the readings are correct (however we had to calibrate the station because initially even when the wind was reading it overestimated the rains). For the drizzle with fog I do not know, I have not yet had such a phenomenon from me. I was also very satisfied with the temperature and humidity sensor. In short, if you haven't done so yet, tell weatherflow about your problems and see what they say, the problem you have with the wind is very strange. For the problem with the haptic rain gauge a possible solution would be to enlarge the support for the pole or flat base, personally I have some ideas in mind to try, let's see.
-
Haven't had Jerry's problems yet not having rain I can say I've seen the vibration issue and ended mounting on a rigid conduit at 6.8 feet. This is the heavy-walled that they thread and use for industrial. Any aluminum antenna or chain-link pole with our frequent 50-60 mph winds would vibrate enough to cause false rain.
The issue I have negates the reason for purchase in the first place was to install near the airport ASOS and show how warm it runs but with any sunny sub 5 mph wind it heats beyond the ASOS and doesn't act like AI is doing anything to compensate for the low wind. It runs warmer than other passive shields I've tested against also. It's apparent to me the AI adjustment for solar and wind is not working at all. Our max solar is around 352 W/m2 which may seem low but this generates enough heat to cause issues with light wind. Yesterday the FARS high was 20° f and the WF tempest was 24° I've had even larger spreads near 10° also I attributed it to snow reflection. https://tempestwx.com/history/62536/day/2021/12/18
This is what it looks like once the wind gets under 5 mph with full sun.

Vibration is not an issue, the station is mounted on an inch and a quarter galvanized pipe with no movement at all. When i looked at the bottom plate it was full of water bubbles from the rain and when the bubbles were removed the readings went back to normal. Now without this problem the rain readings have been very good compared to the two eight inch gauges. I haven't had any high temp readings with my station but we seldom get calm winds down here so will watch for that problem when the conditions are right. Now the drizzle/misty rain is going to be an issue with something that counts rain drops when there are no drops to be counted. I had a rain that had big drops very far apart for a very short period of time and it showed .0022 inches and said very light rain so it just needs drops to count. I don't know what they can do to fix the main problem because of the water issue, it is what it is, two for two heavy rain and wind with the same results and the same fix to clear the problem. Down here on the middle coast of Texas we get a lot of storms with several inches of rain in a short time and gusty winds and this is a real problem in using it for a main station. I will just have tg go with the Davis anny and tipping bucket rain gauge. I don't know enough about the sonic set up but the water is the key i think because removing the water fixes the problem right away. I am waiting for the summer when the Texas sun hits the station and see how it compares to the other two and maybe the R.M. Young shield which i will probably put back in use when we get out of the dense fog period we get this time of year.
