I have had this 01PST since March 2025 and has been faultless , but recently the device was showing offline.After checking the PSU and cycling power although it appears to " boot up" and then shows flashes a Blue led two evey second and what appears to be a amber Led inside flashing every 5 seconds approx not sure is this normal i had the feeling the blue light flashed only every minute or so…, the device is not seen or detected via the Webgui …I dont want to HARD reset unless i am sure I wont lose all my Historical data .Any help appreciated…
Hi @BJENKIAIR, welcome to our community.
The amber light pulse indicates that the CO2 sensor (SenseAir S8) is working normally (not a Wi-Fi or other abnormality indicator)
However, the blue LED is something we’d like to look at in this case. It looks like your monitor loses Wi-Fi connection.
Would you mind contacting us via https://www.airgradient.com/support
I can take a look and guide you through.
Thank you!
