I too run Domoticz on a Raspberry in combination with RFlink, Mysensors Gateway, ESPEasy sensors, and a Milight Gateway. I can also send updates to Telegram.
I have multiple temperature sensors, PIR sensor, Doorbell, Door sensors, and camera's.
Recently installed a PTZ (SD1A203T-GN) on the frontdoor which will use another preset when the doorbell rings, and then sends this photo through Telegram so I can see who is at the door anywhere.
I also receive a message when the frontdoor lamp motion detector is activated, and also send photo's of who is snooping at the frontdoor. If it is night I first switch to dayprofile, since the frontdoor lamp gives more then enough light for a good picture. I switch the camera to day and night based on sunset / sunrise.
I plan to also have a mailbox detector, so I can also send pictures when the mail is in.
