With one of the latest releases of the Alexa Media Player custom component for Home assistant, there is a way to Arm and Disarm the Alexa Guard feature.
Alexa Guard is a feature of Alexa that offers 3 features via your Echo units:
It sends a notification to the Alexa app if one of the first 2 conditions is detected.
1. Listens for sound of alarm (fire, CO, burglar etc.)
2. Listens for sound of breaking glass (optional)
3. Turns lights on and off at night in a typical pattern when you set it to Away mode (optional)
I added this to enhance my current Arm and Disarm Automations that I recently enhanced by adding in my old wired alarm system. Read about adding in a EnvisaLink to my DSC Alarm here .
I will not go into the installation of the Alexa Media player in Home Assistant, there are many articles on it. Please refer to the Wiki or the Forum. there are a few steps to get it working, but I found it pretty straight forward. Also Dr Zzs has some good YouTube videos on it.
I did have a series of Home Assistant automations to turn on and off lights, but the Alexa Guard is a more advanced option and is easy to add in to my Automations with the with the following:
# Arms Alexa Guard. - service: alarm_control_panel.alarm_arm_away entity_id: alarm_control_panel.alexa_guard # (or whatever yours is called)
# Only Disarm if armed. Otherwise, Exit out. - condition: state entity_id: alarm_control_panel.alexa_guard_ # (or whatever yours is called) state: armed_away - service: alarm_control_panel.alarm_disarm entity_id: alarm_control_panel.alexa_guard_ # (or whatever yours is called)
You will have a unique Alexa guard number that will be populated in your Home Assistant Entities and should just be listed once the Alexa Media component is installed.
I use my iPhone for presence detection with the Home Assistant Mobile App to trigger the Arm and Disarm, but I also have it trigger when I manually lock/unlock my Yale front door lock.
