10 Best Apple Smart Thermostats 2025 in the United States

The ecobee New Smart Thermostat Enhanced is a solid choice for anyone looking to upgrade their home heating and cooling system with smart technology. Its compatibility with Apple HomeKit, along with integration with Alexa and Google Assistant, makes it versatile for users of different smart home ecosystems. One of its standout features is its ability to save up to 26% annually on heating and cooling costs by automatically adjusting the temperature when you're away. This can lead to significant savings over time.

The thermostat's learning capabilities are also impressive, as it adjusts to your preferences and accounts for humidity, ensuring comfort all day and night. Installation is user-friendly, often completed in about 45 minutes, especially with the included Power Extender Kit, which is helpful for homes lacking a C-wire. The ability to control the device via the ecobee app from anywhere adds to its convenience, making it easy to manage your home’s temperature remotely. Additionally, the option to add a SmartSensor can enhance energy savings and comfort in specific rooms, although this is sold separately.

Some users may find the need for a SmartSensor to fully utilize the thermostat's potential a bit inconvenient. Also, while it is generally reliable, a few users have reported connectivity issues with their Wi-Fi. Lastly, while the thermostat has excellent features, its upfront cost may be a consideration for those on a tighter budget. The ecobee Smart Thermostat Enhanced is ideal for homeowners looking to optimize energy use and comfort, particularly those already invested in the Apple ecosystem. It stands out for its smart features and energy-saving capabilities, although potential buyers should weigh its cost and additional sensor requirements.

The ecobee Smart Thermostat Essential is a solid choice if you want a smart thermostat that works well with Apple HomeKit and other major voice assistants like Siri, Alexa, and Google Assistant. It supports a wide range of heating and cooling systems, so it fits most homes. The touchscreen and app provide easy temperature control and remote access, letting you adjust settings from anywhere. It automatically follows your schedule to save energy when you're away, which can reduce heating and cooling costs by up to around 23%. While it doesn’t offer advanced learning capabilities like some pricier models, it does include helpful features like indoor humidity detection and a schedule assistant to optimize comfort and efficiency.

The device can also integrate with ecobee’s optional SmartSensors (sold separately), which monitor specific rooms for better temperature control. Geofencing is supported indirectly through the app for turning the system on or off as you leave or return home, but it’s not a standout feature here. Energy reports are available via the app, helping you track consumption easily. Installation is user-friendly, and it can work without a C-wire using an add-on kit. The interface is straightforward with a responsive touch display and app controls, ideal for users who want convenience without complexity.

One downside is that the Power Extender Kit and SmartSensors come extra, which adds to the cost. Also, for those looking for highly adaptive learning thermostats, this model may feel a bit basic. Nevertheless, for Apple users wanting reliable HomeKit integration and energy savings in a simple package, the ecobee Smart Thermostat Essential delivers good value and ease of use.

The Honeywell Home RTH9600WF Smart Color Thermostat is a solid choice for those looking to manage their home heating and cooling efficiently. Its compatibility with Wi-Fi and various smart home platforms, including Alexa and Google Assistant, lets users control their home climate from anywhere, adding a layer of convenience. The ENERGY STAR certification signifies its energy-saving capabilities, and it even offers personalized tips to help you lower your energy use, which is great for environmentally conscious users. The customizable color touchscreen is a fun feature that allows you to personalize the thermostat's appearance to match your home decor.

However, there are some considerations to keep in mind. First, the thermostat requires a C-wire for installation, which may not be available in all homes, necessitating additional setup or a compatible adapter. This could be a barrier for some users. While it has advanced features like Smart Response Technology and geofencing for automated temperature adjustments based on your location, it may not learn as intuitively as other models that are specifically designed to adapt to your habits over time.

The user interface is generally straightforward, but some users might find it slightly overwhelming at first due to the variety of options available. Lastly, it is essential to ensure it is compatible with your specific heating and cooling system to avoid potential installation issues. The Honeywell Home RTH9600WF is a practical smart thermostat that balances advanced technology with user-friendly features, making it suitable for energy-conscious homeowners, albeit with some compatibility caveats.
