Denon CEOL RCD-N9 integration gives errors

Configuration
1

I’m trying to setup my Denon CEOL RCD-N9 using the Denon Network Reciever integration. This is the configuration in the configuration.yaml:

 media_player:
  - platform: denon
    host: 192.168.1.102
    name: denonstudeerkamer
  - platform: denon
    host: 192.168.1.85
    name: denonwoonkamer

I get the following errors in the log:

2019-11-03 15:55:29 ERROR (MainThread) [homeassistant.components.media_player] Error while setting up platform denon

lines.append(line.decode(“ASCII”).strip())
UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xe8 in position 14: ordinal not in range(128)

Any ideas how to fix this issue?

I got one Denon working by (I think!) changing the name in the configuration.yaml to the “friendly name” I gave it: “Denon CEOL”. This Denon now shows up as media_player.denon_ceol.

The second Denon still doesn’t show up at all. Any clues?

media_player:
  - platform: denon
    host: 192.168.1.102
    name: Denon Stud
  - platform: denon
    host: 192.168.1.85
    name: Denon CEOL

The problem automagically solved itself (after the update to 0.101.3, but that’s probably a coincidence). I know see both Denon’s as media players.

Support for the Denon CEOL RCD-N9 is not very satifying (PWON & PWSTANDBY are working, not much else) but that’s for another day.
