I just set these up a couple days ago. Assembly went fine- the video was super helpful, though I wish there was a step showing taking a photo with a phone of sensor for the calibration part.
I did the calibration on my outdoor monitor which was showing as 0 all the time after our air quality improved. Now the outdoor unit is working great and now my indoor monitor is showing 0 in the current reading on my phone but showing a measurable number in all of the graphs, and showing 10.7 on my laptop. The “current” number doesn’t match between my laptop and the phone (android). Both are set for USAQI. It seems like its a different issue than just calibration. Any insight on how to fix this?
