Recently deployed Home Assistant OS onto a rapsberry-pi and directly connected to it via USB A to USB C on my new Open Air Outdoor Monitor (Pre-Soldered Kit). A few days prior I had this same monitor fully functioning and reporting to the AirGradient Web Dashboard. I had intended to move it to Home Assistant so I could have much longer sensor data retention to spot historical trends over months and years.
I attempted to install the config at https://github.com/ex-nerd/ESPHome-AirGradient/blob/main/air-gradient-open-air.yaml and the subsequent steps found at GitHub - ex-nerd/ESPHome-AirGradient: ESPHome config for AirGradient Air Quality Sensor, but it didn’t complete successfully. Instead it stopped at “Writing at 0x0011d45c… (91 %)” and the Open Air Outdoor Monitor become unresponsive, no longer showing any blue light or other signs of life. Did I brick it? Did I do something wrong from what anyone can tell? I am new to both these air monitors and home assistant OS. Full ESPHome log output of the install attempt below:
