10 Best Smart Thermostats 2025 in the United States

The Amazon Smart Thermostat is a solid choice for anyone looking to upgrade from a traditional thermostat to a smart option that helps save money and energy. One of its key strengths is its compatibility with Alexa and Ring, which allows for easy voice control and integration into your smart home ecosystem. The thermostat’s learning capabilities are impressive; it can adapt to your schedule and preferences over time, optimizing temperature settings automatically based on your presence at home. The energy-saving features, including potential rebates from energy providers, make it appealing for those looking to lower utility bills.

Installation is designed to be user-friendly, with guidance available through the Alexa app, making it accessible even for those who might not be particularly handy. The ability to monitor energy usage and receive automatic reminders for air filter replacements adds another layer of convenience.

There are some limitations to consider. The requirement for a C-wire for installation might be a hurdle for some users, particularly in older homes where this wiring isn’t always standard. It's also worth noting that while it works with 2.4 GHz networks, it does not support 5GHz connections, which may limit compatibility with some modern routers. Additionally, while the thermostat can work with temperature sensors through compatible Echo devices, it does not include a built-in microphone, meaning you will need to rely on an Alexa-enabled device for voice commands. The reliance on the Alexa app for many features may also deter those who prefer a more standalone experience.

The Honeywell Home RTH9600WF Smart Color Thermostat offers a blend of modern functionality and user-friendly features. Its ENERGY STAR certification is a significant advantage for energy savings, allowing users to track usage and receive personalized tips. Compatibility-wise, it supports a variety of heating and cooling systems but is not suitable for line volt heating or heating-only oil furnace systems, which can be a limitation for some households. The requirement for a C-wire can also complicate installation for users whose homes lack this wiring.

Remote access is robust, with control possible via mobile apps and integration with smart home systems like Amazon Alexa, Google Assistant, and Microsoft Cortana. This flexibility ensures that users can manage their home's climate from virtually anywhere. The customizable color touchscreen and on-screen display of indoor/outdoor temperatures, humidity, and weather forecasts enhance user experience by keeping critical information easily accessible.

However, the thermostat lacks advanced learning capabilities found in some competitors, meaning it won't automatically adjust to your habits over time. The energy reports and potential for participating in demand response programs are excellent for those looking to maximize energy savings and potentially earn rewards. Geofencing isn't explicitly mentioned, which might be a drawback for users seeking this feature for more automated adjustments based on their location. Installation ease is moderate; while many features are straightforward, the need for a C-wire can necessitate professional installation for those not comfortable with electrical work. The Honeywell Home RTH9600WF is well-suited for tech-savvy users or those with compatible home wiring who prioritize remote control and energy efficiency but might not meet the needs of users looking for more straightforward installation or advanced automation features.

The Honeywell Home RTH9585WF1004 is a solid choice for anyone looking to enhance their home’s comfort and energy efficiency with a smart thermostat. Its compatibility with major smart home systems like Alexa, Google Home, and SmartThings makes it versatile for various users. With a customizable color touchscreen, it not only looks good but also offers an intuitive interface for easy programming and adjustments.

One of its standout features is its learning capability, which allows the thermostat to adapt to your schedule and preferences, optimizing energy usage. Additionally, it provides valuable energy reports, helping you monitor your consumption and potentially save on utility bills. The inclusion of geofencing technology is a bonus, as it adjusts the temperature based on your location, ensuring a comfortable environment when you arrive home.

Installation is reported to be straightforward, making it accessible for most users without needing professional help. Plus, you will receive intelligent alerts for maintenance reminders and any connectivity issues, enhancing the user experience. However, there are a few drawbacks to consider. While it offers many features, some users might find the interface a bit cluttered. The reliance on Wi-Fi means that if your internet goes down, your access to remote features can be limited. Additionally, the pricing may be on the higher side compared to basic models, which could deter budget-conscious shoppers.
