I have both. From my opinion I prefer the rain gauge better on the WS-2902 seems to be more accurate than the haptic detector on the tempest. The tempest doesn't really give you a rain rate per hour like the WS-2902, it just says "heavy" or "moderate"
But I would say the tempest is better on temperature, wind speed/direction, UV index and most of the rest. My favorite attribute is the lightning detection with the tempest.
The highest wind speed I could ever get on the WS-2902 was 28mph (even when a tornado came through), The tempest has exceeded that regularly
I'm undecided on this one. I kinda prefer the ambient app just because it gives you daily/monthly/yearly highest and lowest temperature indoor and outdoor and total rainfall for the day/event/week/month/ yearly total. To me there's more data available with the ambient app. The tempest does seem to be much quicker actually getting real time data though.
There is a good example of use. I rarely use mine and only want some quick, basic information when I do. Then again, I have never claimed to be a "weather guy". The three weather stations are no proof otherwise.
Ecowitt integration by @anon81541053 works great. You’ll need an ecowitt gateway device to integrate their sensors (including the rain gauge) with Hubitat, though.
Honestly I’m not 100% sure on which one is better. The tempest was known to be not so accurate based on the fact that it uses an algorithm and not a rain cup like the ecowhitt. It also registers “rain” from vibration in heavy winds. I honestly haven’t even looked at it closely. As far as getting data into HE, I use Microlines Weatherflow Tempest UDP relay for Linux running on my QNAP NAS in a Linux container to get the data into HE and microlines driver for ecowhitt.
I am using the WS-2902C. It works fine for me. I also get custom predictions from Ambient Weather app. It is always 3 degrees colder here then at surrounding locations and the Ambient Weather app now know that and adjust the low predictions for me so I can now avoid frosts/freezes like happened Monday. Weather Under ground was saying 35 (AccuWeather was at 37) but it got to 31-32 Ambient Weather was predicting 33.
I need one to take care of my plants, most rain (only 1.14 inches this week but the grass if finally growing) and if it will freeze (I have some several plant I over winter) or get to 20 F so I need to protect the rosemary plants too.
Circling back around to this......after some research, it now appears as if I need to "own" the weather station in order to access the data. Is that correct?
I could alternatively just webscrape that particular page.
But do you have a token that you have generated through your own station/api? Or something. There doesnt seem a method to generate a token if I dont own a weather station....
I think WU got rid of the "free" tokens but there are other weather services you could query (depending on your location) that are free. The US national weather service or the Met Office (UK & Australia) are a couple examples. There are weather service drivers that allow querying a bunch of services if you check the community drivers list.
