So the Sunway plugin: Sunway Raambekleding App voor Homey | Homey
has been working for a long time for all the shutter motors we have in our house that are being controller by BREL engines. The RTS remotes work fine however the app has not got any updates for a few years. I have sent an email to Sunway to ask for an update so hopefully they can update it.
I also saw a brel plugin: Brel App voor Homey | Homey
But that needs a separate Hub (Brel Hub) to function.
I was hoping the more people would vote for this the faster it might get an update.
