I have something strange, I have an M5 atom well configured with Home Assistant, etc…
It’s configured in satellite mode, associated with a room in the house, and I have other devices (lights, shutters, etc.) associated with this room. If I ask to turn on/off a light in this room, it works fine, but I can’t control a shutter. Assist gives me this error message (no_valid_targets), extracted from RAW:
“Ouvre le volet” targets all shutter in the current area
Set the “show as” to shutter.
You don’t care about about type of device you have
Device class can be overriden on home assistant, you can play with it if you like, set it on curtain and ask “ouvre les rideaux” it should work.
If you have multiple shutter, add a name or alias to be able to target that particular one via its name.
But the device class is your current problem
