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 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.

The ecobee Smart Thermostat Essential is a versatile and energy-efficient choice for those looking to manage their home climate using their phone. It's compatible with 85% of HVAC systems and supports popular smart home ecosystems like Apple HomeKit, Google Assistant, and Amazon Alexa. This integration makes it convenient to control the temperature using voice commands or the ecobee app, which is highly rated by users. The thermostat also features a color touchscreen for easy on-device adjustments and regularly receives free software updates to enhance functionality over time.

Energy savings are a significant highlight, with the potential to reduce heating and cooling costs by up to 23% annually, translating to about $250 in savings each year. This means the investment in the device can pay off within six months. Additionally, the thermostat includes automatic scheduling and energy usage reports, which can help users optimize their comfort and efficiency. Installation is straightforward, even for homes without a C-Wire, thanks to the optional Power Extender Kit.

However, some accessories like the SmartSensor and trim kit are sold separately, which may add to the overall cost. The compact and minimalist design ensures it blends well with most home decors. On the downside, the initial cost might be a consideration for budget-conscious buyers, and while it doesn't require batteries, reliance on Wi-Fi connectivity means that its smart features are dependent on a stable internet connection. In conclusion, the ecobee Smart Thermostat Essential is ideal for those who want a user-friendly, phone-controlled thermostat that offers significant energy savings and seamless integration with various smart home platforms.
