An idea struck me this morning. Every so often I'll need to either loan out my garage door opener to a family member or the battery will die making it annoying ordeal to get out of the car, walk around the house, get inside, go to the back and open the garage door from the inside, then finally pull my car in.
So what if it were possible to open the door by dialing a number then inputting a 4 digit pin?
Does anyone know if such a thing would be possible? I would think it would be if we were still in the days of dial up modems but is it still possible? Here's the order of events I'm thinking of.
Call Google voice number
Leave message with 4 digits
Google voice creates e-mail with digits
E-mail account is setup on R-pi
Every time it receives e-mail with the right 4 digits it closes contacts on GPIO
Contacts on GPIO are attached to spare remote or possibly even directly connected to contacts on garage door opener.
What do y'all think? Is there a better way to do this? Well other than just putting a little pin pad out side. Yeah that would work, but it wouldn't be nearly as cool.
Is there a way to directly call r-pi via eihernet and type in pin directly?
