Hi AirGradient Forum,
Unfortunately, my AirGradient Open Air does no longer provide CO2 sensor data to my Home Assistant server. So far, I have disconnected and reconnected the AirGradient Open Air from power to restart it. The attempt was not successful in restoring CO2 sensor data updates, though.
It stopped working already a while ago. According to the sensor data recordings in Home Assistant, the latest CO2 data was received on 2025-07-25.
The AirGradient Open Air model is O-1PST. Home Assistant says that Firmware 3.3.9 is installed currently.
Kind regards,
Florian
