10 Best Thermostat Controlled By Phone 2025 in the United States

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 Honeywell Home RTH9585WF1004 Wi-Fi Smart Color Thermostat offers a user-friendly experience with its bright, customizable color touchscreen that makes manual control straightforward and visually appealing. It supports a wide range of heating and cooling systems including gas, oil, electric forced air, hot water, steam, and heat pumps, but it does require a C-wire for power and isn’t compatible with electric baseboard heating. This means you should check your home’s wiring before buying.

The thermostat connects via Wi-Fi and works well with popular smart home systems like Amazon Alexa, Google Home, and others, allowing you to control your home temperature from your phone or via voice commands. It features flexible 7-day programming to match your schedule, along with Smart Response Technology to adjust temperature smoothly. Energy Star certification and monthly energy reports help you track and reduce energy use, and the option to join local utility demand response programs can save you money if available.

Installation may be somewhat technical if you require a C-wire adapter or have an uncommon heating system, so some users might want professional assistance. This thermostat is ideal for homeowners seeking strong compatibility, easy app and voice control, and energy-saving tools, while those looking for more advanced learning or geofencing features may want to consider other products.

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.
