    I just set up the WiFi A3 and all sensors seem to work except the PM2.5 one. The dashboard shows no data points for that. What can I do to get it working?

    Also the Ozone reading is at a constant 20ppb.

    Oh the PM2.5 reading started to work suddenly but Ozone is still a flat line.

    I am noticing a PM2.5 reading of 156μg/m3. That seems… insanely high? How can I test the accuracy of the device?

    Hi,

    Since I had experienced a similar problem with my Smoggie, I’d suggest you try a different power supply, it could very well be it shows exessive ripple on the 5 volt rail, which can affect operation of your A3.

    Which unit is yours?

    Cheers,

    Yours failed after two years though? Mine is brand new. I think maybe my downstairs neighbor is smoking cigarettes in her unit.
