First script, and I am struggling.

I want to turn my TV on (if not on, then on, if on, then next) if possible. I would then like it to go to a specific channel. I found out via a query the number of the app. This is what I have, but I don’t think any of it is right.

'1567648505536':
  alias: Watch Camera
  sequence:
  - data: 
    service: remote.turn_on
    entity_id: remote.living_room_tv
  - data:
    entity_id: media_player.living_room_tv
    source: 143924
    service: media_player.select_source

in lovelace, my mediaplayer card will turn on my TV, so I tried this, but still it doesn’t turn tv on (nor change the source).

'1567648505536':
  alias: Watch Camera
  sequence:
  - service: media_player.turn_on
    data:
      entity_id: media_player.living_room_tv
  - service: media_player.select_source
    data:
      entity_id: media_player.living_room_tv
      source: 143924

tried something new…still no go. Am I getting close?

'1567648505536':
  alias: Watch Camera
  sequence:
  - service: media_player.turn_on
    entity_id: media_player.living_room_tv
  - delay:
    seconds: 5
  - service: media_player.select_source
    data:
      entity_id: media_player.living_room_tv
      source: 143924

what does “states” show when on the channel?
This look correct but I never use for channel, only source like Plex, netflix. I will try to connect TV later and check.

well, I finally got it working. After the update to 98.3, I noticed it said I had an issue in script. I checked, and it told me to delete the delay. So the “working” script is as follows, but now if the TV is on, it will turn it off. Getting close! Would a state statement work?

  alias: Watch Camera
  sequence:
  - service: media_player.turn_on
    data:
      entity_id: media_player.living_room_tv
  - service: media_player.select_source
    data:
      entity_id: media_player.living_room_tv
      source: 143924

After reading more of the docs and looking at examples, this is my working script. Now I can tell Alexa to turn on Camera, and bam, camera is displayed on my living room TV. Wife is very happy.

'1567648505536':
  alias: Camera
  sequence:
  - service: media_player.select_source
    data:
      entity_id: media_player.living_room_tv
      source: 143924
  - delay: '00:00:01'
  - service: remote.send_command
    data:
      entity_id: remote.living_room_tv
      command:
        - right
  - condition: state
    entity_id: media_player.living_room_tv
    state: 'off'
  - service: media_player.turn_on
    data:
      entity_id: media_player.living_room_tv
  - delay: '00:00:03'
  - service: media_player.select_source
    data:
      entity_id: media_player.living_room_tv
      source: 143924
  - delay: '00:00:01'
  - service: remote.send_command
    data:
      entity_id: remote.living_room_tv
      command:
        - right

That was short lived. If TV is off, it turns TV on, but does not switch source. I tried upping the delay, but not go. This is what I get in log.
