Ideally, a thermostat should be mounted on an interior wall, away from temperature extremes.1 Try to choose a central room you use frequently so the thermostat will work according to the needs of that room and not some unused area of the house. When installing your thermostat, avoid: Direct sunlight Outside doors and windows Hallways or other areas with poor air circulation Air vents Areas near the kitchen2 If you have a smart thermostat, you'll need to make sure you're within range of your Wi-Fi router and that no doors, corners, shelves or other items are obstructing the view of its motion or image sensor.3 1https://www.cnet.com/how-to/where-is-the-best-place-to-put-a-thermostat/ 2http://theontimeexperts.com/is-your-thermostat-placement-all-wrong/ 3https://nest.com/uk/support/article/Where-s-the-best-spot-to-install-my-Nest-Learning-Thermostat
