I can reproduce the problem. It is because the TVOC sensor module is missing, it then does not correctly check for the S8. I will let our firmware developer know and we will provide an update asap.
I wouldn’t mind buying one of those as well. I know the difference between my board and the newest ones is the plug header not being included for that module. Do you offer the header it with purchase of the module? Or is there a part you recommend that I can order elsewhere?
Yes I can send you the header with the TVOC module. Just send me a message after your purchase with the order number.
Thanks! I just placed Order #AG-B5IJ4
Same deal. I can get someone to install the TVOC module if I can get it. I can’t find the order # where I bought the CO2 sensor (and a second outdoor monitor, screen reader is misbehaving today…)
I added the pin header to your order.

I seem to have the same issue with One-v9 latest 3.0.6beta firmware.
I do have TVOC module and it does even show some values, but No Co2 values (or they are all negative in the console).
Please send the complete log, especially when the monitor powers on.
Hi Achim,
I left it running overnight, and now CO2 index values are always 0. Perhaps I should force calibration of CO2 sensor somehow?
I’ve used latest firmware from The AirGradient ONE Air Quality Sensor (Presoldered-Version, PCB Version 9) (3.0.6 2Mar24)
You can find txt file export of the console output here: airgradient.txt
Yes, please trigger a CO2 calibration from ‘Edit Location’
and let us know if it gets to 400ppm.
Installed 3.0.7 and still have no co2 or pm25 on the dashboard. The monitor reports PM25 in the console, but no co2, but doesn’t seem to be sending PM to the server.
I just ordered a new one anyway (AG-BV4FW ), as the guy who puts this on the roof for me broke one of the mounting ears… I’ll try to get the log here in a bit. I don’t know if it still has to do with the missing TVOC sensor or what the issue is… (my screenreader doesn’t catch the console output fast enough for me to read the startup messages…)

Can you send a bit longer log? I would like to see a few measurement cycles.

Did you trigger the CO2 calibration I mentioned above?
Yes, but it still says “co2CalibrationRequested:false” in the log.
I’ll try it again, FTHOI
If it still doesn’t work then please send me a message through our support form on our website and we can arrange a trouble shooting call.
No point, as I can’t use zoom anyway… I’ll just have Terry put the second PM sensor back in so I can get my data back, and I’ll wait until I get the new one I ordered this morning…
Thanks @Achim_AirGradient . I’ve put meter outside and requested calibration. It correctly shows values around 400 ppm.
