Cat Flap with ESPHome
MeowPass is an open-source hardware and software replacement for the PetSafe PetPorte cat flap. By swapping the original PCB for a custom ESP32-C6 board running ESPHome, you gain full control via Home Assistant, easier cat management, and better reliability.
I wanted to add a very shy cat to my cat flap, so I decided to create an ESPHome version and build MeowPass.
