This is defying my understanding. I have edited my configuration.yaml file to include the panasonic_bluray media player definition but I cannot get HA to pass the configuration check. I have commented out the entries and uncommented them sequentially, testing the config on each step. When the first two lines are uncommented the configuration check recognizes the panasonic_bluray platform and only complains that the host: entry is missing. Nothing I have tried with the host: entry changes the error ‘mapping values are not allowed here’ except the column indicated in the error message.
media_player:
- platform: panasonic_bluray
host: xx.xxx.x.xxx
HA ver. 2021.12 installation in Docker
Update:
It appears that despite the sample code on the panasonic_bluray platform page, the “-” in the platform: entry line, removing it makes this work. Unfortunately, while the panasonic_bluray entity is now available in my configuration, there seems to be no communication with the DP-UB820 player. I have double checked the IP address. Perhaps there is a setting I have missed in the player.
