I got an AirGradient like 2 years ago and was very disappointed with the quality of the firmware. I wrote my own with Arduino which was good enough for ~2 years. But last week I found out about ESPHome, and they have a blueprint https://devices.esphome.io/devices/AirGradient-DIY https://devices.esphome.io/devices/AirGradient-DIY that just works. My (slightly) customized version: https://gist.github.com/M3t0r/b81ce82796a2ec30f5470f1345f9ca97 https://gist.github.com/M3t0r/b81ce82796a2ec30f5470f1345f9ca... Whatever you think of the openness or quality of the firmware, the hardware is open enough to just flash your own.
