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

The Google Nest Thermostat is a smart and ENERGY STAR certified device designed to help you save energy and stay comfortable. One of its notable strengths is compatibility; it works with most heating and cooling systems, though some may require a C wire or power accessory. The thermostat features Wi-Fi connectivity, allowing remote control via phone, laptop, or tablet, which makes it convenient for families to adjust the temperature from anywhere. Additionally, its integration with Google Assistant, Alexa, and other Matter-certified voice assistants enables voice control, enhancing its usability within smart home setups.

The programmable schedule feature, supported by the Google Home app, allows for easy adjustments to optimize energy use. A standout feature is the Savings Finder, which suggests tweaks to further improve energy efficiency. The thermostat also includes HVAC monitoring to alert users of potential system issues, contributing to proactive maintenance. However, the installation process might be tricky for some users, especially if additional wiring is needed.

The user interface is generally straightforward but relies heavily on the app for detailed adjustments and reports, which might not appeal to those who prefer physical controls. With a glossy finish and rectangular shape, the Nest Thermostat maintains a sleek design that fits well in most home decors. It requires 2 AAA batteries, which are included, and weighs 9.9 ounces. The Google Nest Thermostat is a robust option for those looking to integrate smart technology into their home heating and cooling systems, offering remote access, energy-saving capabilities, and integration with popular voice assistants, though it may require a bit of effort during installation.

The Amazon Smart Thermostat is a solid choice for those looking to upgrade from a traditional thermostat while benefiting from remote access and smart home integration. One of its key strengths is its compatibility with various Echo devices, allowing for the use of temperature sensors and effective control of hot or cold spots in the home. The integration with Alexa lets users manage temperatures remotely via voice commands or the Alexa app, which adds convenience for busy households.

Another notable feature is its learning capabilities. The thermostat can adapt to your routine through 'Hunches,' making automatic adjustments when it senses that the house is empty or everyone is asleep. This functionality not only enhances comfort but can also lead to energy savings, with the EPA estimating an average reduction of $50 on annual energy bills for users of ENERGY STAR certified devices. Additionally, the setup process is guided within the Alexa app, making it accessible for those who may not be very tech-savvy.

However, there are some drawbacks to consider. The Amazon Smart Thermostat requires a C-wire for installation, which may not be available in all homes, potentially necessitating the purchase of a power adapter kit. Users also need to ensure their home HVAC system is compatible, as it's not suitable for 110-240V systems like electric baseboard heating. Furthermore, while it offers good remote control options, it lacks advanced monitoring features that some higher-end models provide, such as humidity sensing or air quality monitoring.

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.
