Use a Raspberry Pi as a VoIP door intercom system.
I use it with my FritzBox to alert all my DECT Phones. Tested on a Pi 2B+ and a Pi Zero with raspbian (and mono).
Please find it here.
All Files are creaded with KiCad.
The new System replaces the indoor part of a RITTO intercom system. The Door itself and the other appartments where not modified.
The old system had a fairly simple circut:
The system is replaced by a Raspberry with a custum Hat (utilizing the GPIOs of the Pi). Bell and Buzzer can operate independently from the new system (in case of Network errors, Bugs, 🙊).
The switch (SW1) can open the door regardless of any errors in the Pi.
The speaker (SP1) will notify about someone ringing the Bell independently from the Pi.
