Fork of frickelzeugs' awesome FingerprintDoorbell with some modifications so that it runs on an Olimax ESP32-POE-ISO board.
For more information, take a look at the original README.
- removed all WiFi related code
- enabled ethernet connection (DHCP)
- disabled breathing LED when idle
- disabled external ringer signal (the pin is used in the ETH connection)
- use GPIO14 as input for the doorbell ring event (for a dedicated button to just ring)
- use GPIO15 as output for a buzzer for an acoustic feedback while the doorbell button is pressed
- remove all NTP related code (see frickelzeugs#84)
