@cq0q I tried a few of the Alexa modules and unfortunally none really worked. Finally I found MMM-AlexaControl.
I took a spare Echo Dot I had laying around, mounted it on the back of my mirror and plugged it into the USB port of the RPi for power supply. That is the easiest way to go:
- Simple module setup and configuration
- no hassle with microphones and speakers
- Setup scenes and similar in the Alexa app to e.g. switch pages on the mirror
- done.
