I have a Gen 3 that I have been using since they came out including a WFM. Previously had a Gen 2.
I use a PWS that is very close and precipitation seems accurate.
However, Rachio does not import the weather forecast from the WU PWS. When I look at the PWS, which is on WU, the forecast looks good. But the Rachio App doesn’t seem to read this and I invariably end up watering even with 80% chance of rain. Today was a 100% chance of rain and forecast of 0.75” but the Rachio calender showed 0% chance of rain and no precipitation.
This has been a consistent problem during my ownership of the Gen 3. The controller dumps tons of water on days that rain is expected. Basically I get zero savings.
What gives? Is Rachio not using the WU forecast in Canada. Whatever they are using is wrong about 90% of the time. Which is impressive, because if you just guess you’d still be right half the time! Basically I have to watch the weather forecast and set up a skip myself, which isn’t the way a smart controller should work.
Today, looking at yesterday’s weather tab in the home page it shows that yesterday was mostly sunny (which it sure wasn’t) but the precipitation number is right. So it’s reading what fell from the skies just fine from tne PWS, but not getting the right forecasts a lot of the time.
Guidance please? If I can’t sort this out, it’s time to find a different system.
