Integration: androidtv Channel UP/Down Swisscom IP2300 not working

Hey all,
I would like to know if someone as find out how to call “Channel_UP” and “Channel_Down” for the Swisscom TV-Box 5 (IP2300). It is the new OS and Hardware for the Swisscom TV.
I found a lot of commands, but some of them are missing:

  • Channel_UP
  • Channel_Down
  • Guide
  • Option

All others are working.

Thanks for the help.
