Doorbell with Home Assistant and push notification

/ September 30, 2019/ Articles, Home Assistant, Uncategorized, Xiaomi/ 1 comments

I made my dumb doorbell smart, because i want to create an integration in Home Assistant. Therefore i made a hack to a Xiaomi Door/Window Sensor.

I desoldered the little contact strip and soldered 2 wires.
I am using a Finder Relais to provide at one side an input of the Doorbell powersupply and at the other site a powerless contact to the sensor.

Finder 40.52.8.012.0000

At last, offcourse the Xiaomi Door/Window sensor is integrated in HA alreaye with the Xiaomi Aqara integration, but you can also use Zigbee2MQTT or another Zigbee integration.

My Home Assistant config is as follow. The code is providing a push notification with an video stream of the door camera and also saving a snapshot. At last there is a condition to prevent repeating doorbells when somebody is pressing repeatedly.

edit: I changed the code a bit. Now there are 2 notifications. 1 with the snapshot and 1 with a video stream. Advantage is that the snapshot can be seen later, when you missed the notification and secondly the videostream is a live video, which is handy. The snapshot is also saved locally in your Home Assistant environment and just called with the url option. This is making the notification fast, without any attatchment.
