Alarm Control Panel: manual and MQTT

I’m not sure if I’m doing it right. I want to have a manual Alarm Control Panel to be operated from the UI and a way to use it also from a remote MQTT panel. But of course they must be stay in sync.

This is my current configuration:

alarm_control_panel:
  - platform: manual
    name: "Alarm"
    pending_time: 5
    code: 1234

  - platform: mqtt
    state_topic: home/alarm
    command_topic: home/alarm/set

in “groups” I show the alarm_control_panel.alarm and it works.
But I cannot keep in sync the MQTT one.

Those are fully different things. Use this to get alarm functions in home assistant with mqtt support. (No external/commersial alarm panel)

The mqtt you have in your config now expects to have fully functional external alarm system that just reports it’s state to HA.
