10 Best Smart Thermostats With Remote Access 2025 in the United States

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 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 Google Nest Learning Thermostat (4th Gen) stands out as a sophisticated choice in the smart thermostat market, especially for those looking to enhance energy efficiency and comfort in their homes. One of its key strengths is its compatibility with a wide range of heating and cooling systems, which means it can be a versatile addition to many households. The included Nest Temperature Sensor helps manage temperature variations across different rooms, making it a great option for larger spaces or homes with uneven heating and cooling.

The learning capabilities of this thermostat are impressive, as it adapts to your preferences over time and suggests energy-saving adjustments. Users can expect to save around 12% on heating and 15% on cooling bills, which can contribute to significant savings in the long run. The integration with both Google Home and Alexa makes it easy to control the thermostat using voice commands or through an intuitive app, which is a plus for tech-savvy users.

In terms of design, the polished obsidian finish and larger display offer both functionality and aesthetics, allowing users to see information from across the room clearly. There are some drawbacks to consider. Although the installation process is typically straightforward and can be done in under 40 minutes, those who are not comfortable with DIY projects might prefer professional installation. Additionally, while the thermostat offers excellent features, it does require a Wi-Fi connection for full functionality, which could be a limitation for some users. The reliance on batteries may also lead to concerns about battery life and the need for replacements over time. The Google Nest Learning Thermostat (4th Gen) is well-suited for homeowners who value energy efficiency, smart home integration, and a stylish design. It would particularly benefit those who enjoy technology and are keen on monitoring their energy usage, while those less inclined to DIY tasks may want to think about professional help for setup.
