auto disable ac

blueprint.yaml

blueprint:
  name: AC Auto-Off When At Setpoint
  description: |
    Turns off an air conditioner when the measured temperature has been
    close to the setpoint for a configurable duration, subject to any
    additional conditions (time of day by default).

    **How it works**

    The automation evaluates two triggers:
      • The absolute delta between `current_temperature` and `temperature`
        (setpoint) on the AC has stayed below the threshold for the
        configured duration.
      • A periodic safety re-check every 10 minutes.

    On either trigger, all of these must be true:
      • The AC is currently on (any non-off hvac mode).
      • Its state has been unchanged for at least the minimum runtime.
      • The current delta is still below the threshold.
      • Your additional conditions pass (default: after 19:00).

    **Requirements**

    The AC climate entity must expose both `current_temperature` and
    `temperature` attributes. This is the norm for single-setpoint modes
    (cool, heat). In `heat_cool` / auto mode the setpoint is split into
    `target_temp_low` / `target_temp_high`, which this blueprint does not
    handle — use a fixed cool or heat mode on the AC for it to work.
