That’s what the automation does.
The ‘doorbell’ is an Xiaomi Button Sensor.
The Camera is a generic FFMPEG Camera.
Clicking the Xiaomi Button Sensor, triggers the Doorbell Automation.
The Door bell automation then:
- Triggers a Doobell Tone on various Google Hoems
- Triggers the Camera Snapshot
- Triggers the Telegram Notification including the Snapshot
- Triggers the Snapshot to be cast to a Nest Hub and a Lenovo Smart Display
