Trouble getting volume slider to work for FireTV

Configuration Frontend
1

I have added my Fire TV via Android Debug Bridge and I’m trying to use the Entity below for the volume slider in this card, but I’m getting the following error:

Entity media_player.fire_tv_192_168_0_57 does not support action media_player.volume_set

My initial suspicion is that it is because it was added via the ADB Integration and not the Android TV Integration? but other functions like touchpad, regular volume buttons etc work fine so I’m a bit stumped.

Any help or suggestions here would be greatly appreciated!

type: custom:android-tv-card
rows:
  - - slider
platform: Fire TV
custom_actions: []
remote_id: remote.fire_tv_192_168_0_57
keyboard_id: remote.fire_tv_192_168_0_57
media_player_id: media_player.fire_tv_192_168_0_57

I am, by no means, an expert here, but I believe its because the slider versus the regular volume buttons are utilizing separate commands. The volume buttons use the ADB “VOLUME_DOWN” and “VOLUME_UP” commands while the slider is trying to set the volume to a determined (based on where you stop the slider) value.

Found this post while trying to see if anyone was able to easily change the slider command or make some sort of work around.

Have you tried using the custom: mini-media-player? You can always use the stateless volume, which although it requires multiple clicks to change the volume, it should work to control it at least.
