YAML sanity check please

The variable trigger has no value in the Template editor, unless you assign one to it.

PSA: When testing trigger templates, use namespace

I don’t often use the template editor to create my own automations because I’ve been using appdaemon for years. Well today, I created my own automation because it seemed silly to create it in appdaemon app because it was very basic. Like all automations I create, I tried to make it as generic as possible. This means, anyone can use it or expand it with as few lines of yaml as possible. Typically when doing this we need templates, so that’s what I did. This lead me to the realization that us…

You can use Trigger IDs to simplify your automation, and you need to place the entity ID under target or data (this is the source of the Message malformed error):

- alias: "Control Master Window Right Socket based on Blind Battery"
  trigger:
    - platform: numeric_state
      entity_id: sensor.blind_master_battery
      below: 25
      id: 'on'
    - platform: numeric_state
      entity_id: sensor.blind_master_battery
      above: 80
      id: 'off'
  condition: []
  action:
    - service: switch.turn_{{ trigger.id }}
      target: 
        entity_id: switch.master_sockets_window_right

FWIW, ChatGPT and other LLM are particularly bad at Home Assistant. They hallucinate answers the majority of the time. And their hallucinations are often plausible-looking, making them difficult to identify without significant HA experience.
