The `mqtt` alarm panel platform enables the possibility to control MQTT capable alarm panels. The Alarm icon will change state after receiving a new state from `state_topic`. If these messages are published with *RETAIN* flag, the MQTT alarm panel will receive an instant state update after subscription and will start with the correct state. Otherwise, the initial state will be `unknown`.
The component will accept the following states from your Alarm Panel (in lower case):
- 'disarmed'
- 'armed_home'
- 'armed_away'
- 'pending'
- 'triggered'
The component can control your Alarm Panel by publishing to the `command_topic` when a user interacts with the Home Assistant frontend.
## {% linkable_title Configuration %}
