I’ve seen a white dot on the far left and the top of the display say “AG Server N/A” for a few moments and then it returns to normal (The message changed slightly in 3.1.9 to show add AG to the message)

A few times I’ve seen the top line of the display change from showing the temp and humidity to just a single dash where each of those were. After a second or two it returns to proper values

Edit: And now I have a single purple LED on the far Left with no other message on the screen. Unclear as an end user what this is supposed to indicate.

I just set up m AirGradient One I-9PSL-DE a few days ago. It’s shown 0 for PM 1, PM 2.5 and PM 10. PM 0.3 is giving readings that seem accurate though. I compared it to a Qingping Gen 2 monitor. PM 2.5 and PM 10 on the Qingping fluctuate as I would expect when opening windows, dusting, vaccuuming, etc… but only the PM 0.3 changes on the AirGradient One.

Since I’ve seen similar post from other users since updating to 3.1.9, I"m going to try the previous firmware version. and test it again. Any other suggestions?

I am getting four red LEDs when CO2 is 1000 PPM . What does that mean please?

I’ve only seen it with f/w 3.19. Thanks.

I also have 4 orangeish/red LEDs at CO2 1095 which doesn’t line up with the expected pattern

Not sure it’s related, but I setup my brand new AirGradient One, I think it updated overnight and it either nuked the S8 and PMS sensors, or my unit died within the first 24 hours.

I don’t think it is related. Did you try and reboot the device?
If it is still a problem please contact our support team.

Already in contact, thanks Achim.

ĂŽ have the same, also 3.1.9 (yet m monitor is only weeks old, I have no experience with former Versions).
Also the graph in the dashboard is colored the same way: yellow above 800ppm, red above 1000ppm.

This has already been fixed in the code and will be rolled out in the next firmware update.

Our developers currently doing some in depth checks of the whole firmware code to see if there are other areas than need improvement.
