10 Best Wi Fi Thermostats 2026 in the United States

The Google Nest Learning Thermostat (4th gen) paired with the Nest Temperature Sensor (2nd gen) is a strong choice for anyone looking to upgrade to a smart Wi-Fi thermostat. It works with most common heating and cooling systems without needing extra wiring in many cases, making installation relatively straightforward even for beginners. The device features a sleek, modern design with a large, easy-to-read display that adjusts brightness automatically, helping you see your settings clearly from across the room. Its interface is user-friendly, controlled through the Google Home app, and supports voice commands via Alexa, Siri, and Google Assistant, offering flexible remote access. The thermostat also integrates well with many smart home setups and supports the new Matter standard, simplifying future compatibility with other devices.

On the energy-saving front, it learns how outdoor conditions affect your home temperature and adjusts accordingly, potentially reducing heating and cooling costs by about 12-15%. The included temperature sensor helps manage temperature differences in various rooms, which is great for maintaining comfort throughout your home. One downside is that while installation is generally easy, some users might still find setup a bit challenging depending on their home's wiring. Additionally, it requires battery power, which means occasional battery changes. The price is on the higher side compared to basic thermostats, but the advanced features and energy savings could justify the investment for many.

This thermostat is ideal for homeowners who want a smart device that is stylish, energy-efficient, and easy to control remotely, fitting well into a smart home ecosystem.

The ecobee New Smart Thermostat Premium is a top contender in the Wi-Fi thermostat category, ideal for homeowners looking to enhance their heating and cooling efficiency. Its compatibility with most 24VAC HVAC systems makes it a versatile choice, and the included Power Extender Kit helps those without a C-wire to install it easily. Users can benefit from its advanced energy-saving features, which claim to save up to 26% on heating and cooling costs annually. The SmartSensor included with the thermostat adjusts the temperature in key areas of your home, ensuring comfort in rooms that matter most.

The user interface is sleek and vibrant, offering a pleasant experience. Integration with popular voice assistants like Siri, Alexa, and Google Assistant allows for convenient control, while the ability to monitor air quality is a thoughtful addition that aids in maintaining a healthy home environment.

There are some drawbacks to consider. The thermostat requires an ecobee Smart Security subscription to unlock all its features, including certain alerts for doors and windows. While the installation is generally straightforward, those unfamiliar with home technology may find the process challenging despite the included instructions. Additionally, the price point is on the higher side compared to basic thermostats, which could be a consideration for budget-conscious consumers.

The Amazon Smart Thermostat offers a straightforward upgrade from traditional thermostats, especially for those already using Alexa and Ring devices. It is designed to save energy and money, with ENERGY STAR certification suggesting about $50 in annual savings and potential local rebates. Compatibility is good for most 24V HVAC systems but requires a C-wire or an additional power adapter, which might complicate installation for some homes. Installation is guided through the Alexa app, which is helpful for beginners, though some tools like a power drill may be needed.

The user interface is simple, with three touch buttons on the device and voice control handled through Alexa-enabled devices, meaning the thermostat itself doesn’t have a built-in microphone. It connects only via 2.4 GHz Wi-Fi, so no 5 GHz support could limit some network setups. Smart home integration is solid, leveraging Alexa’s learning to adjust temperatures automatically based on presence and routines, plus compatibility with Echo devices and Amazon’s Air Quality Monitor for better zone control. Remote access through the Alexa app is reliable and convenient, letting you adjust settings from anywhere.

The thermostat lacks an advanced display or touchscreen and depends heavily on Alexa for voice commands, which might not suit users wanting a more standalone device. The price point is competitive for an ENERGY STAR certified smart thermostat but keep in mind additional costs if a power adapter is needed. This model is best suited for those invested in the Amazon ecosystem looking for an energy-saving, easy-to-use smart thermostat without the complexity of more feature-packed alternatives.
