I have battery powered roller blinds made by Rollease Acmeda.
In addition to having wireless remotes they also have a hub that integrates with iPhone/Android apps as well as Alexa, Google Home, and IFTTT.
The hub has a serial interface and has a pretty detailed instruction manual here
I see that they recently integrated into Control4 home automation.
Im not smart enough to get this to work no matter how hard I try so I’m hoping someone in the community can help?
