co2mini 0.2.0

Monitor CO2 levels with Prometheus and/or HomeKit

CO2 monitoring with Prometheus

This reads from the CO2 Meter and makes it available as a Prometheus service. The core logic comes from this hackaday article.

Setup

Note this assumes you are running on a Raspberry Pi running Raspberry Pi OS (Buster)

1. Install Python 3
2. Install the monitor with python3 -m pip install co2mini[homekit] (remove [homekit] if you don't use HomeKit)
3. Set up CO2 udev rules by copying 90-co2mini.rules to /etc/udev/rules.d/90-co2mini.rules
4. Set up the service by copying co2mini.service to /etc/systemd/system/co2mini.service
5. Run systemctl enable co2mini.service
