Doorbell flow with wavenet voice 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 custom Google Wavenet voice message to your Sonos and Google Cast devices. Please note that live video notifications are currently only supported with Home Assistant iOS app.
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.
If you are satisfied with the regular node-red-contrib-cast voices and only use Google Cast devices, this flow mainly contains irrelevant nodes. Take a look at my simpler doorbell flow instead.
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)
