Get an IFTTT mobile notification when someone pressed your door bell

Belle is an add-on to a house door bell. With a tiny custom PCB containing an ESP8266 ESP-12F module, a buzzer and a connector to the actual bell, a mobile notification via IFTTT can be sent when the door bell is pressed.

Features include

  • Initial configuration setup locally for SSID, password and IFTTT key
  • Deep sleep mode for conserving power consumption in the 3 AA batteries
  • Flash firmware easily with an FTDI chip
  • On-board buzzer to hear the bell press

Final firmware that will setup an access point to add the home owner's WiFi SSID, password and IFTTT Key. After the first time configuration, upon bell press, the ESP8266 will wake up from sleep and send an IFTTT notification that will alert the home owner. After that ESP8266 will go back to sleep until the next bell press.
