Hi
In my apartment we have a intercom system that let's us open the main door to the building. I want to control the door with a Raspberry pi. I'we seen some similar projects with garage openers.
The intercom have 1 button that opens the door. I thought that i could use a 2 way relay to complete circuit for the button and control the relay with the Raspberry pi GPIO. I want to control the raspberry pi with a web interface trough ssl.
Is there any software already made for this project and how should i do the wiring?
