"... I couldn't find a project quite like this online but if you know of one, please let me know.
In my "work" rooms, I have magnetic latches on the toilet doors, presently controlled by a wall switch, but later to be controlled by proximity plates (i.e., no touch!). Upgrade will include RFID to allow "emergency" access (someone collapses). Obviously, the power to the latch itself is a semaphore that can be extended wherever required.If someone switches on the latch and exits, shutting the door behind, we simply switch off the power to that system and reset it. The RFID keys will more easily solve that situation. I am considering ESP8266s.
