Has anyone else done this, is this possible to do with the firmware and board? If so, can it also be used with AirGradient’s Online Panel of the sensor diagnostics and can it also be used with Prometheus Monitoring?
I’ve looked into doing it with esphome. I only found one or two i2c sensors that do ozone and they are exorbitantly expensive.
Jeff Geerling has a prometheus exporter firmware that works with the air gradient sensors.
