Products are mentioned under supported devices in the app store link. Somfy makes all kind of normally hand driven devices automated likes venitian blinds and shutters. Protocols are also mentioned. All are IO
I have Velux and use Velux Active to open and close them based on the temp, etc. Or via App. Unfortunately the IO standard is not open and I can not control them via Homey. But this solution is working for me.
I do not know if Velux Active has an open API which would open possibillities to build an homey app. I would love to get the data from the rain sensor
Why not using i.e. Velux Integra or so with electric control and add a Z-Wave roller shutter like that one from Fibaro, the Fibaro Roller Shutter
That should be then possible to control with Homey.
But that‘s just an idea.
