Hi,
I have an AirGradient ONE (Model I-9PSL), all good. This is not an issue but just a comment.
I used to have it in one room, moved to another for some testing and then back to the initial room.
In this initial room, I have a Danfoss Thermostat. I don’t have the exact difference (I cannot check past values from the Danfoss Thermostat), but I am sure that now the difference between both of them is bigger. It used to be about 0.1 °C, and now it’s 0.5 °C.
It is not a big deal, just curiosity.
