Purchased an AirGradient One Indoor Monitor (I-9PSL) kit in October, came running firmware version 3.1.9. I noticed that the temperature was off when new and it has not changed. It is off by about 6º F. I’ve compared it with five other digital thermometers (three different brands), all of which are within 0.3º F of each other. Is there anyway to calibrate it or replace the sensor? Thank you!
Was it pre-assembled or one you put together yourself?
If you assembled it, ensure that the temperature sensor is in the bottom location and not the top, which often happens accidentally.
Also make sure your sensor is standing up using the provided feet, or mounted to a wall. If it is laying on its back, it can skew the readings.

You were exactly right - I assembled the kit and had accidentally swapped the temperature sensor with the TVOC/NOx sensor. I correct them and it is reading accurately. Thank you!

This just got me also. Temp seemed about 10 degrees F off.
Keyed connectors would be super nice on the next version.
The nice thing about having a standard connector is that you could put any sensor in that has the correct pin out, so I would not be in favor of a keyed connection that only allowed one specific device.
I don’t recall what the printing on the board shows but maybe that could be more clear or instructions clarified to help reduce the chance of misplacement.
Thank you for the suggestion! @MallocArray is right in that it’s quite a common issue and, while we don’t want to charge the connector at the moment, labeling the board more clearly could be a good idea. I will suggest this!
