I have a small domotic projets, and I was wondering if someone could help me here.
I just move in my new condo, and to unlock the front door, I have a special phone
With that phone, I can talk to the person at the door, and unlock the door.
But, my condo is on 2 stories, and I only have one phone, so when someone is at the door, if I'm upstairs, I will not heard it.
Since I always have my cellphone on me, I was looking for a way to make my cellphone ring when someone is at the door.
I'm uploading the images of the phone with it's circuits.
As far as I can see, it's normal rj11 wired.
I find a lots of way to make my cellphone ring on my landline, but no solution to do the opposite; the landline (my door phone) ring on my cellphone.
Anyone have an idea of a way I could do this?
