no air circulation so its readings are always way different than the rest of the house. I have a sensor in my room and that's the only sensor I care about at night. During the day it averages the two living room sensors which are fairly consistent with one another anyway. Allowing me to pick which sensors I care about at which times of the day works great. My house sucks for consistency. I've tried all sorts of things. But short of having it re-ducted or getting smart vents (which actually would help quite a bit for my use case), I've tried everything.
