  • I highly recommend openmediavault as well. Been using it for all my servers. After you get it installed, just make sure to install the omv-extras plugin so you can use docker/docker-compose from the UI (if you want).

    Gives you a nice web GUI and is Debian based so you can dive into the CLI if you want.

    Just be aware that you shouldn’t modify some files that are managed by Openmediavault (like the fstab) and never install a desktop environment or you’ll break openmediavault.






  • i would probably do it with two+ automations. Something like:

    ON automation:

    • trigger:
      • time pattern - beginning of every 3 hours
    • then:
      • start timer with duration 37 minutes (select your timer helper)
      • Turn on AC unit

    OFF automation:

    • trigger:
      • Manual Event
        • event type: timer.finished (case sensitive!)
        • event data : entity_id: timer.[timer_helper_entity]
    • then:
      • turn off AC unit

    STARTUP_CHECK automation:

    • trigger:
      • when home assistant is started
    • if:
      • state - timer helper is idle
      • AC is on
    • then:
      • turn AC off

    Note 1: make sure the timer helper has restore state and time when HA starts enabled

    note 2: automations using the timer.finished event will not trigger on startup if the timer expires when Home Assistant is not running.

    note 2a: the third automation is for your edge case that you reboot/shutdown HA when the OFF automation was supposed to fire. it should ensure the AC turns off after the timer was supposed to be finished and HA is started. this automation does not account for if the AC is turned on manually and you restart HA.

    i can get you the .YAML or pictures when I’m at a computer.
