Seems to be silently fixed for me since last week after firmware update to 3.3.9.
I’m still seeing my CO2 readings drop out occasionally (maybe every couple of weeks or so) until I reboot the monitor. I-9PSL-DE running 3.3.9.
In the Hardware section you can add the column for your wifi signal. Can you see if the signal gets low at the same time as it stops out? -75 or lower.
Are the other sensors still reporting?
I’m sorry, but I can’t figure out how to add the WiFi strength column… And yes, all the other sensors keep reporting, and always have. This is curious, though - I recently installed an outdoor AirGradient monitor, and it looks like the CO2 readings on it drop out at the same time as the indoor monitor, which seems to indicate some kind of backend issue? First screenshot below shows good readings on the PM2.5 sensor while the CO2 sensor readings drop out. Second screenshot shows the outdoor CO2 readings dropping out simultaneously with the indoor readings.
Hi @MMMurphy,
It looks a little bit different on phone, but you can enable the WiFi Strength column here:
Please click on the icon with three columns (as seen in the top-right of the image above). This will let you select which parameters are shown on your dashboard. Single Strength will be one of the options!
If it’s anything lower than -75, the issue could be related to signal strength.
I came to the forum to report this as well. My CO2 is dropping out. It displays zero and one green LED. Only fix is a power cycle. It was working flawlessly for months prior.
Any debug steps I can take?
Hi @cbcjock! Can you please contact us via support form here: https://www.airgradient.com/support/
Please provide the monitor SN as well, thank you!
Any update on this issue? Thanks.
Hi @MMMurphy, does this still occur if you downgrade to older firmware? You can downgrade the firmware under General Settings → Firmware → untick ‘Always update to the latest stable version’ and select an older version. Perhaps 3.2.0.
I’m unsure if this will make a difference since you’ve been having issues with the CO2 sensor for a while, but it may help us isolate the issue.
If the issue continues to occur, could you please reach out to support@airgradient.com and ask for Ethan? I will make sure this gets solved.
Thank you!
This has started happening for me, too. Will contact support.
