Example Usage

To add the alarm to Home Assistant you have a couple of options:

1. Template Alarm control panel in HA

Use the example-config.yaml. It uses a state machine):

stateDiagram-v2
  direction LR
  [*] --> UNKNOWN
  UNKNOWN --> ARMED_AWAY: S1_SOLID_ON
  DISARMED --> ARMING: S1_ON_OR_FLASHING
  UNKNOWN --> DISARMED: S1_OFF
  ARMING --> DISARMED: S1_OFF
  ARMED_AWAY --> DISARMED: S1_OFF
  PENDING --> DISARMED: S1_OFF
  ALARM --> DISARMED: S1_OFF
  UNKNOWN --> ALARM: S1_FLASHING
  ARMED_AWAY --> TRIGGERED: S1_FLASHING
  TRIGGERED --> ALARM: S1_FLASHING
  ARMING --> ALARM: S1_FLASHING
  ARMED_AWAY --> PENDING: BEEP3_ON
  ARMING --> ARMED_AWAY: BEEP3_OFF
  TRIGGERED --> DISARMED: BEEP3_OFF
  PENDING --> TRIGGERED: TIMEOUT
  ARMED_AWAY --> TRIGGERED: SIREN_ON

Loading

One you have the device connectest HA, add a Template Alarm control panel in HA:

alarm_control_panel:
  - platform: template
    panels:
      home_alarm:
        name: Home Alarm
        value_template: >
          {% if states('sensor.alarm_state') == "DISARMED" -%}
            disarmed
          {%- elif states('sensor.alarm_state') == "ARMING" -%}
            arming
          {%- elif states('sensor.alarm_state') == "ARMED_AWAY" -%}
            armed_away
          {%- elif states('sensor.alarm_state') == "PENDING" -%}
            pending
          {%- elif states('sensor.alarm_state') == "TRIGGERED" -%}
            triggered
          {%- elif states('sensor.alarm_state') == "ALARM" -%}
            disarmed
          {%- else -%}
            unavailable
          {%- endif %}
        code_arm_required: false
        arm_away:
          service: esphome.alarm_arm_away
        disarm:
          service: esphome.alarm_disarm
          data:
            user_code: !secret alarm_code

With this configuration you'll have additional entities in Home Assistant:

2. Template Alarm Control Panel in ESPHome
