10 Best Smart Thermostats With Remote Access 2026 in the United States

The Honeywell Home RTH9600WF Smart Color Thermostat is a strong choice if you want reliable remote control and energy savings in your home. It connects via Wi-Fi, allowing you to adjust your heating and cooling from anywhere using an app or voice assistants like Amazon Alexa, Google Assistant, and Microsoft Cortana, which makes it great for smart home integration. The touchscreen is colorful and customizable, showing useful info like indoor/outdoor temperature, humidity, and weather forecasts right on the display, making it easy to understand at a glance.

It’s ENERGY STAR certified, so it helps you save energy and can provide personalized tips and reports to track your usage—handy if you want to lower your bills or be more eco-friendly. It supports many heating and cooling systems including gas, oil, electric, and heat pumps, but it won’t work with electric baseboard heating and requires a C-wire or a power adapter, which means installation could be a bit tricky if your home doesn’t already have this wiring.

The thermostat doesn’t have advanced learning capabilities that some other models offer, so it won’t automatically adjust based on your habits, but it does offer flexible programming to set your preferred schedules. The setup is straightforward if you have the required wiring, and Honeywell includes all necessary mounting hardware and guides. If you’re looking for a smart thermostat with easy remote access, good integration with voice assistants, and helpful energy reports, this model fits well. Just double-check your home’s wiring compatibility before buying, and keep in mind it won’t learn your schedule automatically, so you’ll need to set programs yourself.

The Google Nest Learning Thermostat (4th Gen) is a very capable smart thermostat designed to simplify home temperature management while helping save energy. It supports most common heating and cooling systems without needing a C wire in many homes, making installation relatively straightforward. The setup is user-friendly, especially with the detailed mounting kit and easy-to-follow instructions. Remote control is seamless via the Google Home app and voice assistants like Alexa, Siri, and Google Assistant, allowing you to adjust settings from anywhere. One standout feature is its learning capability—it studies your habits and even considers outdoor temperature changes to optimize your heating and cooling schedules, which can lead to meaningful energy savings over time. The included Nest Temperature Sensor adds flexibility by letting you control the temperature in multiple rooms for better comfort.

Its bright, large round touchscreen with Dynamic Farsight makes it easy to check settings even from across the room, and you can personalize the display style to your liking. The thermostat integrates well with popular smart home systems and supports the new Matter standard for smoother device communication. Some users might find the initial price higher compared to basic models, and while it’s designed for easy installation, homes with uncommon HVAC setups may still require professional help. Although it provides energy-saving reports and suggestions, these are mostly accessible through the app and offer a general overview rather than specialized, detailed energy monitoring.

This thermostat is a strong option for those seeking an intelligent, attractive, and well-integrated smart thermostat that learns and adjusts to your lifestyle, especially suitable for tech-friendly homeowners interested in enhancing comfort and energy efficiency.

The ecobee New Smart Thermostat Premium is a well-rounded smart thermostat that excels in several key areas. It offers excellent remote access capabilities, compatible with Siri, Alexa, and Google Assistant, allowing you to control your home's temperature through voice commands or a mobile app. The included SmartSensor helps to regulate temperature in critical rooms, reducing hot or cold spots and enhancing comfort. Additionally, the built-in air quality monitor is a valuable feature, alerting you to poor air quality and suggesting improvements.

This thermostat is ENERGY STAR certified and claims to save up to 26% annually on heating and cooling costs, making it an energy-efficient choice. Installation is relatively straightforward, even for homes without a C-wire, thanks to the provided Power Extender Kit. The user interface is designed with a large, vibrant display that is easy to navigate.

Some users might find the initial setup a bit complex due to the integration with various smart home systems. The inclusion of a smart speaker and options for Siri or Alexa adds convenience, but it requires an Apple home hub for Siri functionality. It can also serve as a home monitoring hub with additional security features, although this requires a subscription to ecobee's Smart Security plan. The premium materials and advanced features come at a higher price point compared to basic thermostats. In conclusion, the ecobee New Smart Thermostat Premium is ideal for tech-savvy users looking for a comprehensive smart home thermostat with advanced features and efficient energy management.
