I’m wondering that it works because Homey definitely doesn’t have generic Z-Wave drivers for blinds. But ok, I’m happy for you if it now works anyway.
The following devices are officially supported without an dedicated app:
- Zigbee LED lights
- Zigbee Smart Plugs with and without power measurement
- Z-Wave Smart Plugs with and without power measurement
- Matter devices
However, there are two ways to submit a request for an app.
At Athom itself: Request a Brand | Homey
Or here in the community: [Requests] Homey Pro Community App Requests
You can also submit a request to both. However, there is no guarantee that a dedicated app will ever be available.
Therefore, the best way is to buy only devices that are already supported by Homey.
