Dear fellow Mirror Designers,
I wasn’t sure where to put this so I will post it here. From various sources I created a small python httpserver that changes the mirrors volume, starts a podcast (100 Seconds german news, when brushing your teeth:grimacing_face: ) or opens a live stream. This is the code, nothing special but may be helpful for some of you.
I use FHEM and Philips Hue Dimmer Switches to control it:

python3, livestreamer, omxplayer
