Check out their forums for many more details than I could ever remember off
the top of my head.
I bought mine pre-launch was the UDP interface and the lack of moving parts.
- I'm aware of those threads. I was the last commenter a year ago in
the third thread. Some are a bit dated by now.
- I believe the WF UDP driver's author is the second link. I could
provide a similar comparison on my site as well but never got around to it.
- The wxforum link has a lot of comments from some of the more...
typically a bit cranky (shall we say, to be polite)... folks with those
units. You'll recognize the writing style and usernames eventually.
My personal comparison of the WF vs. the VP2:
- temperature and humidity - fine
- wind - fine
- rain - WF not good, not gonna get good in realtime in my opinion. ok
a day later after they adjust, but then why bother measuring bad raw rain
data ?
- (for 'me', living near Seattle, I really wanted accurate rain, so
if I knew then what I know 'now' then I would not have bought a WF)
- lightning - not great but uncertain if it's a limitation in the sensor
from what I read.
- solar/uv/brightness - reportedly so-so, but it's hard to say. I don't
have anything to compare it to here.
- fit+finish - not 'quite' as good as the Davis but close. Very solidly
put together.
- will it last - some WF manufacturing quality problems in initial
batch, but customer support is fabulous replacing bad or failing units
- customer support - excellent. Just as good as Davis so far. Very
nice folks.
- hands-off operation - you need batteries for the Air (reportedly
2-year life) otherwise ok
- flexibility in mounting - the WF is 'very' sensitive to other than
rock-solid mounting poles for the Sky and generates false rain. VERY
sensitive.
- wifi - hub connects with only 2.4 GHz wifi, no 5GHz wifi and no wired
ethernet.
- range - fine for residential, some folks claim insanely good range in
long-range tests
- programming interface - Davis really has none, WF has UDP (realtime)
and Websockets and REST. All work great.
- console - Davis has their 1964-style one. WF has none.
- interface with computer - Davis makes you buy the logger (ugh) but
that 'does' keep a week+ of data if you lose the computer.
- phone/mobile apps - WF has them, but if you upload weewx to anywhere
you can get the same effect for Davis
- moving parts - WF has none, Davis has the anemometer and tipper
(although they last for 10+ years)
- size: WF has two similarly sized sensors (Air = must be in shade, not
weatherproof, and Sky = for solar/wind/rain), Vue has a bigger integrated
sensor suite.
That said, the WF sure is pretty looking and easy to set up. Basically if
you can mount it 'very' solidly and you're ok with uncertain realtime rain
accuracy, it's certainly a nice unit for that price point.
