Does very little compared to other thermostats I've had and it's the least intuitive as well. Sensor is great, but only if you go to bed at 9 p.m. and get up at 7 a.m. ... seriously, these hours can't be changed: Morning: 7 am to 11 am Midday: 11 am to 4 pm Evening: 4 pm to 9 pm Night: 9 pm to 7 am To solve this problem users posted in the community "just carry the sensor around with you."
