The Moving ELectrons blog documents a project to create a solar powered, HomeKit connected outdoor fence door monitoring device. Once setup, the door’s state (i.e. open/close) can be monitored and used in automations within the HomeKit ecosystem.

A partial list of hardware components used in the project:

Homebridge manages communication with HomeKit framework/devices. Additionally, the voltage supplied to the battery and the door switch status are monitored online through Adafruit IO portal. This allows us to keep tabs on battery performance and check if the solar charger is getting enough sunlight during the day to charge the battery.

Code is written in CircuitPython. Follow Adafruit’s instructions for installing it on the M4 Express board.

All the needed files are included in the project’s GitHub repository.
