Home Security Box call you if intruder breaks in. Using improvised wemo switch.
This recipe is used after hacking into the Wemo switch. The Wemo box has an ON/OFF switch on a PCB which pulls a pin to ground.This pin can be pulled low externally and then using this recipe a call is made. In this case the pin is pulled low by my home security buzzer. If the buzzer goes off I get a call. It takes about 4sec to 40 sec for a call to go through IP. Some logic conversion has to be done because the switch only works when it is released and the security system simply give out a 12V high. Wemo switch runs on a 5V switcher supply internally.
