yeah.. the ambient light sensor isn't perfect.. put it's good enough. mostly just seems slow to update and report back.
temp sensor seems a little off though. I'll put it in a room with my ecobee sensor tonight and see the difference. ecobee sensor I measured against 2 other thermostats and all three were within a degree. but yeah, the bathroom (where this is) measured like 68° while the two rooms next two it measured 72° (occupied) and 71° (not occupied)
anyway, just being picky. it definitely falls into the "good enough" camp. about the worst to say is I wouldn't use the temp sensor because I already have the ecobees, and they are consistent with each other.
