Sky-high utility bills are a sure sign that your strategy of trying to remember to adjust your thermostat every time you go to bed and wake up, and when you leave the house and return just isn’t working.
The shock is always the biggest during the winter months, when you need your heater, and again during the summer months when you need your air conditioner. Investing in a smart thermostat will save you money all year long, and keep you more comfortable, too. The basic models will let you easily set schedules for every day of the week and let you control your HVAC system from anywhere you have broadband access. The more sophisticated models will include features such as remote sensors that can monitor the temperature in multiple rooms in your home, to eliminate hot and cold spots.
The lists below are sorted by manufacturer (through Wyze Labs) and then by price. The Mysa and Sensibo products after that are specialty smart thermostats for things like baseboard heaters and stand-alone air conditioners. If you’re looking for a particular brand, click on it from the list in the left-hand column.
