10 Best Thermostat Controlled By Phone 2025 in the United States

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 Google Nest Thermostat is a user-friendly smart thermostat designed to help save energy and maintain home comfort through phone control. It connects via Wi-Fi, allowing you and other family members to adjust the temperature remotely from your phone, tablet, or computer. The thermostat works with Google Assistant, Alexa, and other smart home systems, so you can also use your voice to control it. Before buying, it's important to check if your heating and cooling system is compatible, especially if your system requires a C wire for power, as some setups might need extra accessories. Installation is straightforward for most homes, with detailed instructions and mounting hardware included.

The interface is simple, featuring an LCD screen and button controls, while the main setup and scheduling happen through the Google Home app, which many find intuitive. The Nest Thermostat offers helpful learning capabilities, such as automatically adjusting when you leave the house to save energy and suggesting schedule tweaks through its Savings Finder feature. It also monitors your HVAC system’s health and alerts you to possible issues, which can prevent costly repairs. Energy reports and support for programs like Nest Renew let you track usage and prioritize cleaner energy times. However, this thermostat does not have a physical lock feature, so anyone with app access can change settings, which might concern some users. It runs on two included AAA batteries, so you don’t need to worry about power outages affecting its operation.

This thermostat is a good choice for homeowners who want an affordable, easy-to-use smart thermostat with solid remote control and basic learning features. Those with complex HVAC systems or a need for advanced locking or multi-zone control might want to consider other options. For most users looking to reduce energy bills and control heating and cooling from their phone, the Nest Thermostat offers a reliable and well-supported solution.

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.
