Eating dust? My "ancient" VP2's performance (talking temp/humidity performance, which is what this has been about) holds a candle for no one to this day, and will continue to do so until whomever proves otherwise. I can't just willy-nilly buy PWS's just for the sake of comparison, evidently you can.
Keep us posted, will ya? ;)
I'm just not into "grandpa's" weather station.
Just because you've got a bad taste in your mouth with Davis, be sure of one thing, Gramp's station performance will kick the crap outta anything from Acurite.

ooohhh... I'm so scared...   :roll:

surprised at the knee jerk reaction here again
It's like buying a car without wheels. Why bother. Get me something that does the job outta the box.

funny it is in your signature a vp2 with optional FARS (extra cost) to keep the temperatures inline .  as with the AIR sensor you can buy a 3rd party optional shield or just do DIY solution its not rocket science and your local DIY store probably has everything you need just like a cheap $20 bathroom aspirator which can be easily adapted. AIR is a first generation product just like all products early production runs against later production runs will differ and see improvements as time goes bye. has the VP2 always had a SHT31 ? has the VP2 always had a aerocone rain buckets , improvements always happen over time. as you can see from below

AIR model is not even a year old how old is the VP2 ? im sure in the early days of a VP2 release there were anomalies its the companies that listen to feedback and act upon them which make the difference long term. Weatherflow is listening and acting .

SHT11: The previous standard VP2 T/H sensor is part 7346.166 which has now reached revision J. This part is thought to use the middle-ranking SHT-11 part (SHT-10 being unused by Davis), which is specified as having a typical temperature accuracy of 0.4C (at 25C) and for humidity of 3% over 20-80% RH, rising to 5% at 0 and 100% RH. The Vantage Vue is also thought to use this same SHT-11 sensor element.

SHT15: In 2015, Davis introduced part 7346.174 which uses the enhanced SHT15 T/H sensor. This option has two main benefits:

In addition to lowering the typical temperature accuracy at 25C to 0.3C, the SHT-15 has an altogether shallower temperature/accuracy profile, which offers a roughly doubled temperature accuracy at eg -10C and 40C;
The baseline RH range of the SHT-15 is 2% over 10-90% RH and maximum error at 100% RH is reduced to 4%.
This 7346.174 sensor is a direct drop-in replacement for the older 7346.166 part and may be used with no change in temperature offset being necessary. Note however that 7346.174 has only been made in limited quantities and may become increasingly difficult to source.

SHT31: The newly released SHT31 sensor is built into Davis part 7346.070. This is plug-compatible with the 7346.166 sensor and can be used with any VP2 station from 2006 on. However: The temperature calibration of the SHT31 sensor is slightly different from the previous sensor and if the 7346.070 sensor is used with a VP2 station prior to the AS revision then the temperature will read 0.5C high and therefore a temperature offset of -0.5C needs to be entered into the console in this scenario. (And conversely if eg an older 7346.166 sensor is used with a VP2 station of AS revision or later then the temperature will read 0.5C too low and an offset of +0.5C needs to be entered.)

I Tried to find a topic already, but didn't find any.

As you can see by reading the above, any time that the WeatherFlow station comes up here it turns into an argument over the Air's lack of an integrated solar radiation shield.  Even the WF creator himself was driven from this forum by the hostile attitude!

I jumped on the campaign when it was first announced, and have been happy with the product concepts and direction it is moving...even if they are a year behind their original schedule.  There is an invitation to join their new support forums in the latest Indiegogo update, should you want to read about other customers' siting experiences with the actual product.....
Yep.  It's a real shame the opposition to change some folks have here. 
No doubt, but for myself, that's an absolute cop out. You give me something that's superior to what I have (GL with that, and obviously price considering) and I'll jump off what I have in a split second. This as is, ain't it.....YET. Allow it to sit in the sun with a true quality shield and maybe we'll talk.


I've had mine for several months and like it very much.
No one is trying to convince you to buy one.
You've stated the reasons for your dislike so why keep posting?
Do you have trouble letting things go?
Always have to have the last word?

I put mine in a stevenson screen
(only shield people should be using for any weather station if they want accurate temperature readings)
reports exactly the same temperature as a Davis station (I put my Davis VP2 sensor in their as well (I separated it from the ISS))

Personally, I wouldn't have a Davis anything.  I had one for a while.  Wasn't impressed.  Overpriced hype in my mind.

If something like this can be had for a reasonable price, I might be interested.  I'm not interested in paying for a name.  Best one I had was an Oregon that they stopped making.

Banners, tags, widgets, etc. are why I have Signatures turned off.

You don't even know enough about it to know what I'm getting at.   :roll:

Can we cool this thread please.

Keep it about Weatherflow.

Thank goodness.....finally....

Would it be reasonable to start talking about creating a weatherflow forum, or is that premature ?
Or should folks just avoid the hostility here and shop/discuss/share elsewhere (which would be sad) ?

I think a dedicated weatherflow forum would be a good idea.
