10 Best Wifi Thermostats 2025 in the United States

The Amazon Smart Thermostat offers a straightforward way to upgrade from a traditional thermostat, especially for those who want to save energy and money. It works with most 24V HVAC systems but requires a C-wire or an additional power adapter, which is important to check before buying. Installation is guided through the Alexa app and is relatively simple, though some tools like a power drill might be needed. The user interface is basic with just three touch buttons on the device itself, but it is complemented by easy remote control via the Alexa app or voice commands through Alexa-enabled devices. This means you can adjust your home's temperature from anywhere, which is convenient.

It integrates well with Amazon's smart home ecosystem and supports temperature sensors from compatible Echo devices to better manage hot and cold spots. Energy-saving features are strong, as it is ENERGY STAR certified and uses Alexa’s smart learning to adjust temperatures automatically based on your routines. However, it doesn't have a built-in microphone, so voice control requires another Alexa device. The display is minimal and focused on simplicity rather than rich visuals.

It connects only to 2.4 GHz WiFi networks, which could be a limitation if your home primarily uses 5 GHz WiFi. If you’re already using Alexa or Ring devices, this thermostat fits nicely into that setup and is an affordable, energy-efficient choice. For those seeking a thermostat with a more advanced screen or broader WiFi compatibility, exploring other options may be worthwhile.

The Google Nest Learning Thermostat (4th Gen, 2024) is designed to be an energy-efficient and user-friendly device, ideal for those wanting to manage their home heating and cooling with minimal effort. A significant strength is its broad compatibility with most 24V systems, including gas, electric, and radiant, meaning it should work in many homes without requiring additional wiring, making installation straightforward and typically under 40 minutes.

The inclusion of the Nest Temperature Sensor helps address hot and cold spots, ensuring more precise temperature control across different rooms. The thermostat’s smart scheduling and Adaptive Eco feature further enhance energy savings, with the potential to reduce heating and cooling bills by up to 15%. Smart home integration is seamless, as it works with both Alexa and Google Home, allowing easy voice control and app management.

The user interface is intuitive, with a large, borderless display and Dynamic Farsight providing clear visibility of the information from afar. However, while it offers numerous benefits, the price might be a consideration for budget-conscious users. Additionally, its reliance on a CR2 battery, though included, may be seen as a minor inconvenience for those preferring battery-free devices. Nonetheless, for those seeking an advanced, stylish, and energy-efficient thermostat that integrates well with smart home systems, this product is an excellent choice.

The Google Nest Thermostat is a smart wifi-enabled thermostat designed to make your home more energy-efficient and comfortable. One of its standout features is its compatibility with both 2.4 GHz and 5 GHz Wi-Fi networks, making it versatile for various home setups. The thermostat is ENERGY STAR certified, which suggests it’s efficient at saving energy. You can also check its compatibility with your home system using the Nest Compatibility Checker, which ensures you're making a suitable purchase.

Note that some systems may require a C wire or other power accessories for proper installation. Installation is generally user-friendly, especially since it’s designed to work without a C wire in most homes, but users with specific systems might find it a bit more complex. The thermostat has a sleek design and a backlit LCD display, although the small 2-inch screen size might not be ideal for everyone. The user interface is managed through the Google Home app, which allows you to create an energy-saving schedule and control the thermostat from your phone, laptop, or tablet. The app also features a Savings Finder to suggest further energy-saving tweaks.

Remote access and smart home integration are strong points, especially with compatibility across Google Assistant, Amazon Alexa, and other Matter-certified voice assistants. On the downside, the lack of a lock feature may be a concern for some users looking for added security. The built-in HVAC monitoring provides alerts for maintenance issues, aiding in keeping your systems in good shape. The product is lightweight and comes with necessary mounting components, making physical installation straightforward. It also includes a one-year warranty. For those seeking a balance of energy efficiency, ease of use, and smart home integration, the Google Nest Thermostat is a solid choice.
