      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:

      Uses:
      python3, livestreamer, omxplayer

      #!/usr/bin/python3 -u
      
      host_name = '10.0.1.49'  # Change this to your Raspberry Pi IP address
      host_port = 8000
