This might be the killer feature I mentioned in a previous post on this article. I own a 120 year old house with odd nooks and crannies and strange airflow. My thermostat knows the temperature in my living room, but not upstairs by my bedroom, which can be 10°F warmer or cooler, and we have to set the downstairs thermostat to odd temperatures at night just to make it remotely comfortable, and it's rarely the same temperature from night to night. That hassle would be worth some amount of money to eliminate. $150? Hell no. $100? Probably not. $60? Sign me up!
