For sunshades though, I think the best solution is a rain sensor. Weather services are not the most precise tools. There’s very cheap DYI (just two wires) ones, like Aqara flood sensor (Homey bridge supported), connected to a special circuit board, which closes the circuit as soon as water drops appear: > [@Home made rain sensor idea](https://community.homey.app/t/home-made-rain-sensor-idea/29117/14): > > Hi Richard, The sensor you can find on aliexpress don’t need to order the switch as you can’t connect that to Homey. The casing you will have to print yourself or let it print in a shop. Drawing you czn find in the link below.

At summer it’s not the problem. It will dry fast. At cold days with high humidity, even due will raise the alarm. For normal rain, I put a piece of aluminium tape at the bottom edge. So the water will not stay at the border but drips of. . Ready to go, but 3 to 4 times more expensive, and bridge supported: Popp rain meter: POPP Z-RAIN (700168) > **[POPP](https://homey.app/nl-nl/app/com.popp/POPP/)** > > Engineered in Germany. --- _[View the full topic](https://community.homey.app/t/is-there-a-homey-bridge-app-that-is-able-to-use-expected-rain-as-a-trigger/113356)._
