10 Best Wifi Thermostats 2026 in the United States

The Amazon Smart Thermostat is designed for people looking to upgrade from a traditional thermostat to a smart one, especially if they already use Alexa or Ring devices at home. It works well with Alexa, allowing you to set schedules, control temperature by voice, and even have the thermostat adjust automatically based on who’s home or current temperatures. This makes it convenient and helps save energy, which could lower your bills by about $50 a year according to energy experts.

Installation is fairly straightforward with step-by-step help through the Alexa app, but it requires a C-wire, which some older homes might not have without additional work. The thermostat’s user interface is friendly, especially if you’re comfortable with Alexa. Remote control is a strong point, letting you adjust settings from anywhere using your phone. It also integrates smoothly into smart home routines, making it a good choice for Alexa users wanting to tie their heating and cooling into their wider smart setup.

Backed by Honeywell’s trusted technology, this thermostat offers a reliable experience. If you want an affordable, energy-saving thermostat that works well with Alexa and you don’t mind the C-wire requirement, this thermostat is a solid pick.

Its new Adaptive Eco mode smartly keeps your home comfortable while maximizing savings when you're away. The thermostat supports Matter, allowing easy integration with a wide range of smart home devices.

Although it’s compatible with many systems, some very old or unusual HVAC setups might not work perfectly.
