Thermostats make some of the best “smart” devices to have in your home. Imagine having total control over the temperature of your house, all without having to fiddle with the controls personally. A smart thermostat could be just what you’re looking for.
Naturally, you’ll also want to make sure your smart thermostat works with most smart home devices. Double-check what voice controls you can use with your thermostat – some only work with certain smart speakers, for example, or only integrate with certain smart home ecosystems, like Google Home.
Furthermore, double-check to see what exactly a smart thermostat controls with your air-conditioning system. Doesn’t monitor the air quality, or does it just control the cooling system? The smart features integrated into a thermostat will help you choose between them beyond what you’ll save in terms of energy costs.
Today, let’s explore some of the best smart thermostats.
