I used a lot of scripts made by others and integrated them.
My solution is a compex one, uses:
- domoticz, dzvents
- mqtt
- node-red, some nodes
- apache
But a good scripter can scripts this all in dzvents, so that seems to be an easier road to follow then my infra, but in my case that was already there..
I will attach a screendump and a dump of the flow in node-red (for the dzvents scripters among us...)
How it works:
1. Ring the doorbell ( a wifi doorbell from action)
2. Node-red via mqtt cathes this on signal and starts a flow
3. The flow speaks (The doorbell is ringing on my nest hub)
4. the flow grabs every 5 seconds a image off my webcam (9 euros sonoff) and sends the link to my NEST HUB.
The nest hub grabs the image via the received link from the apache server
5. After a minute the last image stays fixed on the screen of the NEST HUB for a minute
6. Nest hub will be put in normal mode (alternative is say ok google stop..)
7. All the images are stored on a local folder on my rpi and are synchronised to my nas (NAS is not always on, only daytime)
8. So no payed services, and everything local
PM: the included flow uses a injector to trigger the flow. Normally this will be triggered by a received message from the doorbell via mqtt/domoticz in nodered...
