Is there a Homey Bridge app that is able to use expected rain as a trigger?

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:

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. Like in the link and go to remix

Hi, yes, the alarm stays on if there is still water on the sensor. 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. [20210828_084221]

Ready to go, but 3 to 4 times more expensive, and bridge supported:
