10 Best Thermostat Controlled By Phone 2025 in the United States

The Amazon Smart Thermostat is designed to help users transition from traditional thermostats to a more energy-efficient solution. One of its main strengths is its compatibility with Alexa and Ring, allowing for easy control via voice commands or the Alexa app. It also features temperature sensors that can address hot or cold spots using compatible Echo devices, enhancing comfort throughout your home. Energy savings are a notable highlight, with the potential to reduce bills by about $50 annually due to its ENERGY STAR certification.

Installation is fairly user-friendly, guided by the Alexa app, although it requires a C-wire, which might not be available in every home. If your home lacks this wiring, you’ll need to purchase a power adapter separately. The thermostat has a pleasant ability to learn your habits through 'Hunches,' adjusting temperatures automatically based on your activity and schedules.

There are a few drawbacks. It only supports 2.4 GHz networks and lacks built-in far-field microphones for voice control, meaning you’ll need an Echo device for that feature. Additionally, while it provides a range of app-based features such as energy reports and geofencing, it may not be as intuitive for users unfamiliar with smart home technology. This thermostat is a great fit for tech-savvy homeowners looking to save on energy bills and control their home environment remotely. However, those less comfortable with technology or lacking the necessary wiring might find it more challenging to set up and operate effectively.

The ecobee New Smart Thermostat Premium stands out with its compatibility with a wide range of HVAC systems and popular smart home platforms like Siri, Alexa, and Google Assistant. It offers excellent connectivity via Wi-Fi and Bluetooth, ensuring you can control your home's temperature from your phone or through voice commands. The user interface is intuitive, featuring a vibrant display that makes it easy to navigate and adjust settings. Learning capabilities are strong, with the included SmartSensor helping to minimize hot and cold spots by adjusting the temperature in specific rooms.

Additionally, the thermostat provides detailed energy reports, assisting you in optimizing energy usage and potentially saving up to 26% on heating and cooling costs annually. Geofencing is another useful feature, automatically adjusting the temperature when you leave or return home to save energy. Installation is made simpler with the included Power Extender Kit for homes without a C-wire, and the comprehensive quick start guide helps streamline the setup process. However, some users might find the need for a subscription to access certain advanced features, such as smoke alarm detection and break-in alerts, a bit of a drawback.

Additionally, while the built-in air quality monitor is a nice touch, it may not be a primary selling point for everyone. The thermostat's design is sleek and modern, and the added functionality of a smart speaker with the choice of Siri or Alexa integration is a significant plus. This thermostat is well-suited for tech-savvy homeowners looking for a comprehensive, smart home-compatible solution that offers convenience, energy savings, and enhanced home monitoring capabilities.

The Google Nest Learning Thermostat (4th Gen) is an advanced and stylish option for those looking to control their home’s temperature from their phone. It’s compatible with a wide range of heating and cooling systems, making it versatile for various homes. The inclusion of the Nest Temperature Sensor allows for better temperature management in different rooms, addressing hot and cold spots effectively. One standout feature is its energy-saving capabilities, which can average savings of 12% on heating and 15% on cooling bills, thanks to its learning abilities that optimize heating and cooling based on your preferences and external conditions.

The user interface is friendly, with a 60% larger display that's easy to read from a distance. It has Smart Schedule and Adaptive Eco features that not only learn your routines but also suggest adjustments to enhance energy savings. Installation is typically straightforward and can be done by users themselves in about 40 minutes, which is a plus for those who prefer DIY projects.

The Nest Learning Thermostat offers many advanced features, but it may not be the most budget-friendly option for everyone. Additionally, users who do not have a compatible smart home setup might not benefit fully from its smart capabilities. Although installation is generally easy, some users may still find it challenging if unfamiliar with home wiring or technology. Finally, while it works with Alexa and Google Home, integration with other smart home systems may not be as seamless. The Google Nest Learning Thermostat (4th Gen) is ideal for homeowners seeking efficiency and modern control over their heating and cooling, especially those who already use smart home devices. Its ability to learn and adapt sets it apart, but potential buyers should weigh the cost and installation considerations before committing.
