I also starter to use owm to warn about weather change. I have roof windows with open-close sensors. Currently I’m using 3h forecast for rain reading. If 3h forecast rain is more then 0 and window is open I get warning. For now I I’m satisfied. It’s not like rain-alarm (real time reading) rather it’s forecast but ok for warning if I left windows open while forecast is changing. P. S. Buienradar is completely useless for anything aside few countries like already posted [here](https://community.homey.app/t/rainradar-rainalarm-european-coverage/14507). P. P. S. It would be Gr8 to have either 0 or the value like you suggested above. Thnx for the app, works gr8. --- _[View the full topic](https://community.homey.app/t/archived-app-pro-openweathermap/1048)._
