So far I came across this little Add-On, called DSS VoIP Notifier. Having it installed on my Home Assistant instance, I am able to:
- call my landline phones from Home Assistant
- Bind the Camera Live Feed with the SIP Client using the Fritz!Box Web UI
So theoretically I could now remove the transformer, the Telegärtner TS2-a/b and the DECT-Modul to replace it with a ESP or Shelly, that sends me events/states of the pushbuttons at the front door and the gate.
This solution would be very simple and would allow me:
- to ring the phones when someone is ringing the door bell, as before
- show the camera feed on the phone to see, if that person is at the door or at the gate
I would loose the following features:
- Talk with the person at the gate. The current TS2-a/b has got a speacker and microphone connected, however performance has always been miserably (i.e. not able to understand each other) as such this function has never been used.
- Open the door by the gate remotley via a button press on the phone. (However that function has also rarely been used, as you can simply reach over the door and open it from the inside.
