So I have several Xiaomi Aqara buttons. Today I want to explain how to use this button as a smart doorbell that will play sound to your Google Home device through Home Assistant.
First of all let’s create a script that will be executed when button pressed. In your
doorbell: alias: Doorbell sequence: - data: entity_id: media_player.googlehome4615 #Your Google Home device service: media_player.turn_on - delay: 00:00:03 #To make sure we are connected to Google Home - data: entity_id: media_player.googlehome4615 #Your Google Home device media_content_id: https://your.homeassistant.domain:8123/local/doorbell.mp3 media_content_type: music service: media_player.play_media - delay: 00:00:05 #The same as doorbell.mp3 file ledgth - data: entity_id: media_player.googlehome4615 service: media_player.turn_off
doorbell.mp3 available by that url you need to place it to
/config/www in your Home Assistant.
Now we need to create a handler of Aqara button in
- id: doorbell_button_handler alias: Doorbell button handler trigger: - event_data: entity_id: binary_sensor.lumi_lumiremoteb1acn01_01ef8594_1_on_off event_type: click platform: event action: - data: entity_id: script.doorbell service: script.turn_on initial_state: true
This automation will call our doorbell script on any type of click: short, long or double. That’s basically it for initial setup. All other things depends on your imagination. For example we can add a notification automation:
- id: doorbell_notify alias: Doorbell notify trigger: - entity_id: script.doorbell from: 'off' platform: state to: 'on' condition:  action: - data: message: "Someone near your front door" service: notify.push
