Hack the Intercom part 1

A lot of us have an intercoms to let our friends and service workers into the building.  I want to modify mine so that every time someone rings my buzzer I can get a notification on my phone and if I choose to, buzz them in.

Here is the pdf schematic of my device (4-wire setup).


Here is the actual photos of the circuit:


I want this first meetup to just talk about what actually needs to be done?  How does one capture the signal from the device and how can you send the signal back to the device?  Once you capture the signal, how can I get it on my phone?  And lastly once the phone receives the notification, sending one back.

This is scheduled for variety cafe but if it is too crowded I'll just move the event to the bar down the street.

    I have recently thought of this exact idea! I would love to contribute to making this a reality. Any word on the location of this meetup?

    Huh, very interesting idea for a meetup! I'm not well versed enough in most hacking activities, but if there's any kind of "home improvement" stuff that I can share here, it would have to be HTPC building.

    Currently looking into Raspberry Pi seedboxes as well, for what it's worth...

We just grab a coffee and speak French. Some people have been coming every week for months... it creates a kind of warmth to the group.
