I am new the the forum and have been reading all the discussions as try to decide what station to buy.
The Vantage Pro 2 looks like a nice station, but seems to be near point in life cycle where next generation will be released.
Does anyone have any idea if this is a sometime in 2020 release or how long later this may happen?
Am struggling with spending this much on something that may be obsolete soon and would go with an ambient 2902 interim.
Thanks for any ideas to help decide should i wait more before going all in with a vantage pro

The answer to this familiar question hasn't changed: A VP3 (or whatever it may be called) may well appear at some future date but there is no sign at all of it being imminent. The emphasis of VP2 development is steady evolution and the introduction of important new accessories like Weatherlink Live. Davis development resources are pretty committed with the continuing development of weatherlink.com, the Enviromonitor family of products and other projects and so my guess is that any VP2 successor is at least a couple of years away, very possibly more.

With a Davis, and with the VP2 you can't go wrong...
You'll enjoy,

Is it April already? The only time that the release of a VP3 is ever discussed is on April Fools Day.
My advice to anyone waiting for the mythical VP3 to come along is to stop making excuses and just buy the VP2 already.....
-

So it could be amusing if Davis were to announce it on April 1st 202x - no-one able to decide if it's for real or not. Can't decide whether that would be brilliant or really stupid marketing!
-
Too bad Acurite has not released the Atlas Elite. I think it would have expedited the release of the VP3.
Two things Davis should do:
- Davis should release a new display that is slim and sleek and reasonably priced and in COLOR. It doesn't need any sensors (no internal temp/hum/barometer) and it doesn't need an RF radio and no logger port. Doing this will make it a great looking and reasonable priced display. All it needs is WiFi and it would get live data from a WLL. This way anyone can upgrade and you could have multiple displays for a reasonable price, no need to make it a fully capable device which would basically amount to a WLL plus a display (that would be bulkier and not as slim and sleek and be outrageously priced, probably at least $100 more than a WLL...that would not be good).
- Davis should come out with a new version of the ISS with I2C bus. This way better sensors could be used (SHT35) and even enable new sensors types (PM2.5, Lighting... etc.) to be added. Existing VP2 and Vue consoles should still work (except for displaying new sensors types). WLL would be upgraded via firmware to support new sensor types.
It just seems like the logical next step. The WLL will be a critical component and hence why we saw that first. All this just my opinion without having any insider knowledge. The WLL is a very capable device enabling most popular 3rd party weather applications to already get live data.

Isn't that called a tablet? The WLL API is published of course so it just needs someone to write a suitable app, assuming that they think it's a commercial proposition. But one issue is how the display should deal with WLL's capabilities, eg how do you design a display for a user who has eg 3 anemometers or 3 rain gauges - not saying it can't be done but designing real flexibility into the display isn't easy, though the Davis Bulletin on weatherlink.com is one sort of model.
-
I wouldn't call it a tablet if it wasn't a touchscreen. It could just be a color display with buttons like the WS-2000. Ambient calls that a tablet, but I refuse to call it that and I call the WS-2000 display just a display console and I don't use the word tablet.
The future Davis display could be touchscreen or not. I don't think that matters much. What is important is that all live data is visible at a glance without needing to interact with the display. Buttons or touchscreen should only be for graphs or looking at data tables and setting up alarms and preferences.
And yes it could very well just be an app. Then all someone would need is a cheap Android tablet where you could disable sleep and the app just runs continuously. Because WLL API is known I'm frankly surprised that nobody has yet come out with an app with these capabilities.
The bigger point for me is the update to the ISS with I2C bus. I want to be able to easily swap in an SHT85 even if Davis updates the ISS to I2C but decides to stick with the SHT31.
-

Yes, and Amazon is selling the Fire 7" / 8" / 10" for $30 / $50 / $100 on Black Friday sale as I write this.
Let's see *any* low-volume PWS vendor manufacture a color console for $30...touchscreen or not.....
-
I wouldn't call it a tablet if it wasn't a touchscreen.
Are there any that would qualify as a mainstream tablet and don't have a touchscreen? How else would you control the apps on a tablet if it didn't have a touchscreen? And I'm no expert but I would have guessed that adding a touchscreen is a cheaper option than including multiple mechanical control buttons around the case.
The bigger point for me is the update to the ISS with I2C bus. I want to be able to easily swap in an SHT85 even if Davis updates the ISS to I2C but decides to stick with the SHT31.
Yes, and I respect that point of view but would also suggest that 90+% of VP2 buyers are totally oblivious to that nicety. (I agree that it's a good idea, but not sure that it would win many extra customers.)

I could give an app a go (Mac OSX). I can distribute though app store etc.

No..make app run on Android so that we can take advantage of cheap tablets.

While I desperately want an updated VP of some sort III or 3 or tres, I don't care, I'm through holding my breath after a 1/2 decade since the rumors started.
Here's a slightly related question, though, for those of us thinking next year will be when I can get to put up a new wind device and make getting a new one (and probably my last) once again.
Are the newest ones coming out of the factory as robust, solid and well built as they were say 5 or 7 years ago? The reason I ask is I see the occasional complaint that the temp/humidity sensor has failed, or has failed, replaced and failed again.
Then there is the rinky dink appearing rain collector, which not having seen one but seeing pictures and reading messages seems to not lend itself to heaters if you wanted to install one.
Or the rain collector having a tipping spoon (do they all now?) rather than the rocking collectors which some have criticized for not getting several drops during a heavy rain while the spoon resets itself.
What about the boards and other sensors? Are they as relatively free of EMF problems as those built awhile ago, or has the updated circuitry and design taken short cuts?
Has anyone who has an older VP2 and now gotten a new one since the last round of 'improvements' have come out gotten a chance to give a good look over and seem satisfied, or are you wishing you'd gotten one of the old ones since it was better?
Just curious.

Doesn't really matter the age of your VP2, everything new that's available can installed on any old one, as long as it's a VP2, not a 1. The only exception I can think of is the anemometer, that changed in 2013 but is still compatible with any VP2.
-
Do you know if it was the large-cup vs. small cup choice on the menu?
I had toyed with the idea of using a (now-discontinued) Davis box that took a RM Young 5103 wind sensor and converted it to work with a VP2 ISS and I'm hoping that even though they don't make that adapter any more, I bought one new and was hoping to use it with a 5103 already up on my tower (no climbing, no paying anyone to climb) to use it.
Just curious.
I think Greg had that setup on his home station and don't know if it is still something he uses.

No, not cup size, :-" it's was completely redesigned so the parts are no longer compatible. I knew RMY anny was compatible with the VP2, I didn't know that it's no longer a available.
-
Well in line with previous changes I would reckon the next generation won't be compatible with anything previous and if it can be subscripted then it will be that as well :)

I can do android easy
And target tablets
One thing is Google play store does have requirement for
relatively recent android version
I can create dual 32/64 bit app too
I will need a beta tester who has a WLL

Perhaps...all I know is that the VP2 design is now ~14 years old so change is almost surely inevitable. I've damn sure gotten every pennies worth out of mine, (especially since I bought this wireless 24hr FARS 12 years ago for about $575 when they were going for 4 figures)...and continue to do so. =D>

Yes, and I respect that point of view but would also suggest that 90+% of VP2 buyers are totally oblivious to that nicety. (I agree that it's a good idea, but not sure that it would win many extra customers.)
I think Davis would gain quite a bit more customers if they switched from LSS to I2C, as it would not be something that goes unnoticed to 90+% as you suggest, because it is the I2C bus that will enable more types of sensors to be released, PM2.5, Lightning and more. I'm sure that many existing Davis customers would then not only update to the new ISS and new transmitters but also those that don't yet have a WLL. It would bring in a lot of sales from existing customers to get the new features. If Davis does the smart thing and also upgrades to the SHT35 then they can also advertise increased accuracy and precision. I agree with you that now yes 90+% don't know about this, but it needn't be so if Davis markets it right. And by us bringing this up in the forum we help and educate even more. The I2C bus could just be the solution to the dreaded short life of the current SHT31 and its wet bias, as better sensors like the SHT35 could be used. In the end nobody will know of I2C but they will know that only with the new VP3 (or whatever it's called) could you get these extra features and better sensor quality.

I sure do. See my "Wind" page: http://rogerscityweather.com/wxDavisYoung.php (http://rogerscityweather.com/wxDavisYoung.php)
With the exception of my Ham APRS (http://www.findu.com/cgi-bin/wxpage.cgi?call=KE8DAF-13) linked feed, all wind data is from the RM Young.
I bought a spare UAI when they were being discontinued. I figured if disaster strikes, I can always get another SIM module and a new RM Young Wind Monitor. (although I have the "Junior" one currently.)

After reading all of this summary is other than a few seconds slower refresh rate the Ambient 2902 is in effect comparable with the VP2 for 5 times less the cost. Arguably even more cost effective due to the disposal every 12 to 18 months temp/humidity sensor.
I am surprised as had weather monitor 2 for 20 years and am looking to replace, but after all the discussions on the board the premium for davis just doesnt seem worth it with the sub par temp humidity sensors.
Has anyone compared accuray of the UV and solar sensors, but again for a $300 premium is it worth it.
Sorry guys but I was a big Davis believer but this forum has me more in doubt than ever
-
The VP2 is quite a bit better than the Ambient WS-2902A (or WS-2000) and it has to do with a whole lot more than just being a few seconds faster. Even Ambient Weather will sell you a Davis station and has admitted that their branded stuff is for a different purpose. It just depends on what you are looking for.
The Davis VP2 is still like the gold standard of weather enthusiasts. You get what you pay for.
- better sensor with VP2: SHT31 instead of SHT30
- greater humidity range
- higher wind speed range to 200 mph
- more frequent gust readings
- more 3rd party software and hardware compatibility
- better quality, will last longer
- greater console range at 1000 ft
- Altimeter support at the console with WLL and Vue console
- larger range gauge diameter
- separate sensor components rather than all-in-one
- Fan aspirated radiation shield option
- and probably a whole lot more.
-
What I thought, but there is miles of complaints re the SHT31 and see refrence to SHT35 and 85 and people holding out for I2C bus.
Seems like VP2 is a dinosaur in terms if not keeping up (i'll admit i am do not fully understand the above bus and sensor benefits) but premium that is not current is a mind spinner
-
There is not a benefit to the I2C bus for sake of the bus itself. It isn't the bus difference that makes for a better sensor. The issue is that Senserion the manufacturer for the sensor only makes their better sensors available with the I2C bus. There are other sensor manufacturers (for temp/hum and other types of stuff like PM2.5) and the industry has pretty much embraced I2C as the standard. It is true that this is one of those issues where the VP2 is showing its age. But a Davis VP2 with SHT31 (LSS bus) is still better than an Ambient SHT30 (I2C bus) no matter what. At least you can easily replace the VP2 SHT31 for $50 and the VP2 will then continue to provide superior data.
-
I'm sure that many existing Davis customers would then not only update to the new ISS and new transmitters but also those that don't yet have a WLL. It would bring in a lot of sales from existing customers to get the new features.
I totally disagree with this - other than the few vocal critics of SHT31 on here, IMO it would make zero difference to prospective sales. YMMV and of course there might be other new features introduced at the same time that were more of a sales pull so it's rather a hypothetical question. And, let me repeat just for the record: Most of our customers' VP2 T/H sensors reach at least 5 years of service before any significant issue is reported and 10 years is not that uncommon.
But the point is perhaps moot in that I suspect the Davis EM node is more of a pointer to future interface options and includes analogue voltage & current inputs, pulse or contact closure counters, SDI-12 (probably most of the many sensors that aren't covered by the analogue inputs) and, yes, I2C. In a sense, an EM-based system might actually be a better model for a putative future VP3, but it would maybe use the EM's intrinsic ZigBee mesh network to communicate to a local receiver rather than a cellular base station.
-
I had not looked at the Enviromonitor that closely. Very nice to see I2C support! The WLL, Weatherlink.com 2.0 and the Enviromonitor shows that they aren't sitting on their laurels. VP3 is coming, the foundation is there. It has certainly taken longer than we hoped but they are certainly doing it right.
-
Thanks re the SHT30 vs 31 vs 35. Went to Sensorian page and understand now the diff is a few 10ths of a degree or 1% or so RH based on were in range. Helps alot.
the I2C will give option for more sensors to be added but perhaps Davis will find a way to have WLL be able to receive this data from a remote transmitter kit ( i call them hub) to not require full VP2 ISS upgrade.
or at mimum make majority of sensors reusable so dont need to buy all in.
Really want to go VP2 route, but will stink if few years from now would have to go all new if Next Gen whatever is called comes out and invested a lot in non compatible VP2 sensors.
I would think a lot of people would be upset if this was case due to mass quantity of VP2 out there, unless most people have unlimited budget.
Thanks guys as I know am over analyzing this
-

I think you have to define your timescale. In 5 years, almost certainly there will be a son-of-VP2. In 1-2 years it's distinctly less likely, but no-one outside of Davis knows for sure. And then would you want to be a 1st-year guinea-pig for a brand new line of stations? (Which would of course have been well-tested, but that's no substitute for extended field testing by thousands of users in different climates around the world. Plus it's often the case that not all features, supplementary sensors etc etc are available at launch time.)
My advice would be to wait until eg January. By then the 2020 Davis catalogue is likely to have been published and you'll be able to see what new items are planned for availability in the 2020 year. There's usually at least a few new items, but sometimes minor and sometimes more major.
-
Thanks for tip. when does Catalog usually come out in Jan?
Is Enviromonitor compatible with Wireless VP2?
Seems like path to have I2C and way to get the SHT 85 sensor to work with VP2
-
Thanks for tip. when does Catalog usually come out in Jan?
Unpredictable I'm afraid. Has occasionally been out in late December, but other years delayed for a month or two, though I think they do try and aim for Jan 1st.
Is Enviromonitor compatible with Wireless VP2?
Not as yet. It has been promised for a while and I'm guessing will really happen RSN. But you have to remember that EM uses a different wireless architecture (ZigBee IIRC) from VP2 so a VP2 wireless ISS won't be able to talk direct to an EM node without some sort of adapter. The next step may actually be to get a cabled VP2 ISS talking to an EM node. Or maybe there will be a VP2-type ISS version but fitted with a SIM board that can communicate with EM nodes. There are different possibilities that could I guess one day morph into a VP3.
-
Thanks again.
Does WLL connect with Enviromonitor?
Maybe that will be the way to integrate
-
Does WLL connect with Enviromonitor?
Sorry, no. WLL listens to VP2 transmitters and so uses their wireless system. EM is something different. But who knows whether Davis have thought of a WLL for EM for the future ;)
-
This is a great thread. I hope Davis is reading and taking notes.
After the VP3 (I2C support with new sensors and nicer display solution) then Davis needs to focus on the Vue 2. The fact that the individual sensors and super cap are not user replaceable parts on the Vue as they are on the VP2 is bad, very bad.
-
I agree great discussion and hope these are already on the dev roadmap and in testing. 8-)
Too bad is so hodgepodge. I am reading about enviromonitor gateway, and looks like is compatible with cabled VP2.
Where the costs kill you will be that the gateway requires cellular connection with exerpt of costs here:
Update Interval Price Product #
CDMA (US) 5 minutes $280 6892
15 minutes $220 6894
60 minutes $160 6896
GSM (US/CAN) 5 minutes $320 6892A
15 minutes $260 6894A
60 minutes $200 6896A.
These prices make WLL much more palletable.
Environmeter has some nice features for argiculture professionals.
Davis definitely seems to be evolving and positioning for future integrations
Based on this have to wonder if there will be a VP3, or if envirometer will be the professional grade future.
If this is the case A WLL for envirometer, or integration to existing one should be developed for people who have Internet Wifi based connectivity as not everyone needs expensing cellular option.
This is a great forum and getting me more pumped to get station up and running again
-
Remember that EM is a product line for use (primarily) in farm fields that may be some real distance (potentially several/many miles) from the farm office. So there is no option for the basic EM product but to use a cellular gateway - it's the only approach that can work pretty much anywhere. Then the data plan costs also include all the cellular comms - it's just a single all-in payment.
Cabled VP2 ISS units can be connected to an EM gateway, but not (yet) with EM nodes. (An EM system consists of a single communications gateway plus up to 80 nodes, each able to accept 4 sensor inputs.)
[Blatant plug: we are apparently the biggest EM reseller in Europe, according to Davis! So we have some experience with the EM product lines]

Is 2 to 5 years the average life of STH sensor across all brands or what station has the best humidity sensor?
This sensor was demise of my WM II
-
what station has the best humidity sensor?
My SHT31 is 5 months old and has no bias, certainly not to the degree that has been reported here before. However, that said, I'd vote the sensor that Rainwise uses. But that's Davis VP2 money as well, if not more.
-
Okay.how is th new single spoon rain guage accuracy? Another new in validation item?
See several people say the use the rainwise ew111 guage with vp2, but not sure how?
Seems like rainwise is nudging ahead with sensors. Not sure costs tho
-
See several people say the use the rainwise ew111 guage with vp2, but not sure how?
It's as simple as twisting two wires together and plugging it into the ISS with the same type phone jack. Registers exactly the same as the stock tipper.
-
Really easy stuff with water proof splice connector. Do you use rainwise rain guage? Does it have snow melt heater option? Or what do you use?
I have old double tipper bucket from my wm2. May run side by side with vp2 if I go this route tocompare.
. For the vp2 cost boggling rain guage sounds like weak pt alomg with temp sensor which is in new revalidating phase

You don't need to waterproof anything, the wires are inside the bucket.
Can't comment on the heater, I'm in Tucson.
The nice think about using the RW bucket (at least for me) is that I was able to mount it on my cinder block wall an make it level as well as secure, something I couldn't do with the VP2 as it's on a tripod and was susceptible to shimmy. On paper the RW is twice as accurate (in real life, probably even better), has an 8" catch vs 6.5", and more consistent as well. Great mod, especially how easy it is to do. =D>

What stations or sensors run sht35 mentioned by galfert?
Is there a way to swap out sht35 with the sht31 stock sensor for vp2?
Ask as while we are discussing retrofit the vp2 and in effect creating our own Frankenstein vp3 want to go all in on mods feasible.
Thanks guys great discussion today

None.
Not unless you've got a degree in electrical engineering.

I have been reading more re the sensirion sensors.
Per their spec sheet here they only have one sensor not I2C: model SHT31-ARP-B which says analog
https://www.sensirion.com/fileadmin/user_upload/customers/sensirion/Dokumente/2_Humidity_Sensors/Sensirion_Humidity_Sensor_SHT3x_Table_Overview.pdf
They must have custom sensor being manfactured because VP2 specs dont match the above.
I am no expert but if all but 1 are I2C they may at some point need to evolve to this.
Wishful but sharing a thought
-
It's like this... there are three types of Sensirion temp/hum sensors.
- LSS (Legacy Sensirion Sensibus, a proprietary protocol that Davis uses)
- Analog
- I2C which is digital
Of these three types they now have stopped making the LSS type. Davis probably has stocked up on these in order to keep making the VP2 and the Vue stations and have spare parts available (only for VP2). So yes the supply for LSS sensors is gone. Unless Davis has some special contract to be able to still order them and Sensirion is making them as a special order. We just don't know. I hope the supply of LSS type is really gone so that Davis will be forced to switch to I2C soon.
The SHT35 never existed in any other form than digital I2C type.
The SHT85 is the same as an SHT35 that has been mounted onto a PCB that makes it easier for electronic hobbyist and probably small integrators to use. In other words the SHT35 has to be SMD (surface mounted soldering, but there is more to it as the soldering process can damage the sensor).
There are no stations with with SHT35 or SHT85 that I know of. But the Acurite and Ambient/Ecowitt stations use I2C sensors, so you could replace the SHT31 and SHT30 that each of those ship with for an SHT85 (or even an SHT35 if you've got the means).
Recently someone posted that they upgraded their Ambient/Ecowitt to SHT35. Kind of pointless in the case of Ambient/Ecowitt because in software it is limited to 10% - 99% RH range. That isn't a fault of the sensor, that is just how Ambient/Ecowitt have programmed their firmware.

Regarding Davis and a VP3 there is one more thing I wanted to bring to light.
Davis recently changed the rain tipper on the VP2 from a double tipper to a single tipping spoon. It was a rather interesting change. Many users are testing it and I'm not sure I've seen anything conclusive if it is better or the same reading that thread discussing it. But that isn't why I bring up that new tipper. I bring up the new tipper because although recently released it does not incorporate recent technology that Davis filed a patent on rain gauge working methods.
What this means is that Davis has newer technologies that have not yet been incorporated into any current products. Therefore it only makes sense that if these newer patented technologies are truly better, then we will see them in new products. Sure Davis still needs to test these and see if they really are better technologies, but from what I read I was impressed (yes I read the whole patent filing and it was mostly boring stuff but there were some nuggets in there). Davis can also licence the technology for other companies to use. But one thing that doesn't make sense is for Davis to do nothing with these patent technologies because patents run their course and then the technology is in the public domain. So in order to capitalize on them it wouldn't make sense to not do something with them.
Therefore it would be a neat thing to see this patented rain gauge stuff in a VP3. The neatest things I read in the patent was the use of a rain tipper that weighs the water between tips. It means that water can be measured by weight on each tip and the tipper doesn't need to fully empty as the difference is what would be used as a value. The tipper could be covered during tips so that it acts as an accumulated buffer and then drains when the tipper returns to upright position (no missed rain during tips). Also the patent discusses electro magnets to make the tipper move faster. Because it measures water by weight sand or silt on the tipper gets zeroed out also. It was a very impressive patent to read. I would like to see this technology realized in a new station. The current new tipper does not incorporate these patented ideas.
-
In my instances, I've found that using weight is superior to using volume when calibrating my RW tipper.
-
Surely most automatic rain gauges (other than syphons and drop counters) work on weight - they're not aware of what volume is passing through.
-
Surely most automatic rain gauges (other than syphons and drop counters) work on weight - they're not aware of what volume is passing through.
My point is that I've measured with both volume (800ml = 1" of rain) and weight (800 grams = 1" of rain) while calibrating my RW tipper and found that using weight is consistently more accurate than using volume. Obviously using my scale is more precise than using my syringes. Not only, it's ahellofalot easier to do with a scale as well.

How are the real world field validation results going with the new single spoon?
Interested as I know some people prefer Rainwise 111, which I dont think has heater option/
Didn't know Davis had newer rain guage tech not released in addition to the single spoon so trying to understand how released product is performing.
I have old weather monitor 2 dual tipper so curious how single spoon works in case swapping out to dual is better to have heater option

the single spoon tipper is a big improvement over the older dual spoon design particularly noticeable under light rain short periods .
as for a console alternative
if you have a 7'' , 10'' ,12 '' tablet running IOS or Android then here is a simple approach to just display live data , it does nothing else no charts no forecast , no additional data other than realtime data sniffed over the local network.
works with options Meteobridge Logger NANO(SD) or Meteobridge Pro or TPlink type Hubs with meteobridge software installed
and Weather Link Live.
It is a free app ..no ads , no purchase, no monetizing just free , * note it is a simple live data screen nothing else .
some screenshots and will make available end of the festive season as somewhat preoccupied to spend any time on support or ideas . open to ideas but keep it simple and the most common values will not get lost in a congested design.
however for Davis owners who own Weather link Live you may as well use the Davis app which is also free and probably better supported ?
to add windchill
to add heat index
to add light mode
to add ..open to ideas...

Helllo,
Did someone have any news about Vantage pro 3 ?
Thanks

Have a look at the WeatherLink Live. This is as close to the Vantage Pro 3 as you're likely to see for a few years.

There was mention of some patents that Davis holds.
What sort of things do they patent, such as a better rain sensor? Temp sensor? The patents must spell out how they do something.
I agree to hold a patent and either not market it or use it makes little sense if it is of value.
Thx for any discussion.

The only thing I know for fact that Davis has a patent for is their ISS's 24hr radiation shield.

Thx, I'm not savvy enough to search registered patents to see what various companies have filed.
Radiation shields that I have are good enough for me. Dale

Well, I didn't search for it, I happened along the info years ago. Besides, you asked, I answered.

All info is good, thx for sharing what you ran across.
I hope to live long enough to see a real revision of the Pro released. The incremental changes keep it a top choice.
