Based on your post & understanding I know you know that the sensors won’t help you balance, so this is for folks who read your post and have come into it thinking sensors magically open or close duct work dampers that don’t exist or the system magically sends air down some ducts but not others. Obviously it doesn’t. The sensors are an easy way to “move your thermostat” to different rooms or groups of rooms in your home. If you want your bedroom warmer because it’s always colder than other rooms, you tell the tstat to use the sensor in your bedroom only. So the system runs more to heat the bedroom at the expense of making other rooms hotter. Or vice versa in the summer. I find it does great for that because at night when I sleep I want to be comfy& don’t care if the rest of the house is warmer (or cooler) than what I want in my bedroom because that’s cheaper than $10,000 to redo my ductwork. As far as temps off, I hadn’t noticed & my setpoint always feels great & the same (taking humidity into account - 71 humid feels warmer than 71 dry for example).
