Hi @Marco,
Thanks for letting us know. For WI+, we rely on IBM. You are correct in that we the interpolated data is between multiple stations and if they are all reporting 0, then you would see 0 precipitation as well.
You are only getting 4 stations back because the other stations that are closest to you are not reporting data, therefore we aren’t listing them. We are investigating if we can get more stations back to you and make sure that those are reliable.
With that being said, I would still recommend that you use that station since it is reporting precipitation that you are expecting. The only changes would be to adjust your zone’s advanced zone settings. https://support.rachio.com/hc/en-us/articles/115010542148-What-are-Advanced-Zone-Settings-
Please let us know if you have any other questions/concerns!
Cheers!
