    A few clicks from here.

    1. Copy the YAML and replace any placeholder entity IDs.
    2. In Home Assistant, go to Settings → Automations and create an automation.
    3. Open ⋮ → Edit in YAML, paste the automation, and save.
    4. Test your trigger and check the automation trace before relying on it.

    One automation at a time. The butler checks YAML structure; your Home Assistant installation is the final check.

    Simple by design
