Only last night I got the keypad running again, and was trying to insultate the wires to improve its uptime.

So I coated two connections between the rasberry pi and the relay which is attached to the door. After coating, it seemed like I somehow failed these connections, because the software exited normally (opendoor.py was still being called and sent success messages), but the door was not opening. I tried to unglue them, but when i was taking off the glue, I disconnected one of the wires that was at this 3-way junction. Then I resoldered the wires but to no avail.
