Simple doorbell flow with voice message and Home Assistant video notification
Doorbell flow that sends a Home Assistant mobile notification with a live video feed to your phone or tablet and plays a voice message on a Google Cast device. Please note that live video notifications are currently only supported with Home Assistant iOS app.
If you are not satisfied with the standard node-red-contrib-cast voices then check out my wavenet doorbell flow instead.
Flow
As seen above, my doorbell simply sends a payload to the MQTT topic "doorbell". The MQTT node is easily replaced by an Event state node, deCONZ in node, Flic node, etc, depending on your setup.
Copy the flow below to your clipboard and then import into Node-RED using the Import From > Clipboard (Ctrl-I) menu option.
Remember to add your camera to Home Assistant and install the required nodes before importing this flow into Node-RED (check out Node types box on this page)
