Well I love my new Iro so to further step up my game I ordered a PWS, the Ambient Weather WS-1400-is all-in-one with wind, rain, temp, humidity, solar, and uv sensors (key for me since Rachio uses these values if you have them for ET calculations.) I will have its wireless box the “ObserverIP” connected to a Meteobridge that will allow posting not only to Weather Underground but also PWSweather so Rachio can see it.
When buying an all-in-one PWS (vs. something like a Davis Vantage Pro 2 which can have its sensors spread around your property) you really have to pick and choose what matters to you most in terms of siting the PWS. For me I will mount the PWS about 7 ft. above the ground so temp, rainfall, humidity, solar, and UV should be quite accurate. I will have LESS accurate winds however vs. the national weather service recommended height of 33 ft. above ground level. Does this hurt my Rachio calculations? Shouldn’t it in a way make it more accurate because I’m reporting the lower level winds my yard is experiencing anyway or is the problem that the Rachio calculation accounts for the fact winds are reported at 33 ft typically so with my siting it will hurt my accuracy of ET calculations? Hope that makes sense but I’m still pretty happy because I feel with accurate rain, temp, humidity, solar and UV right on property I am getting pretty close…
