10 Best Apple Smart Thermostats 2025 in the United States

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 ecobee New Smart Thermostat Premium is a fantastic choice for those looking to upgrade their home heating and cooling systems with smart technology. It works seamlessly with Apple HomeKit, Alexa, and Google Assistant, allowing for easy voice control and integration into a broader smart home setup. One of its standout features is the included SmartSensor, which helps manage temperature in the most used rooms, making it more comfortable by reducing hot or cold spots.

In terms of energy savings, it boasts a potential reduction of up to 26% on heating and cooling costs, an appealing feature for budget-conscious users. The built-in air quality monitor is another valuable asset, alerting you to poor air quality and reminding you when to change air filters. Moreover, it includes smart alerts for open windows and sudden temperature drops, which can help prevent damage to your home.

There are some drawbacks to consider. While the installation is generally straightforward, users without a C-wire may find the setup a bit more complicated, despite the inclusion of a Power Extender Kit. The need for an ecobee Smart Security subscription to access some features may also deter some potential buyers. Additionally, the interface, while vibrant and user-friendly, may take a little time to get accustomed to for those who are less tech-savvy. This thermostat is ideal for those who want an all-in-one solution for home comfort, energy efficiency, and air quality monitoring.

The Google Nest Learning Thermostat - 3rd Gen (2015) is a programmable smart thermostat known for its ability to learn your heating and cooling preferences and automatically create a schedule. One of its standout features is the Auto-Schedule, which eliminates the need for manual programming by learning from your adjustments. Home/Away Assist is another useful feature that adjusts the temperature when you leave, ensuring energy is not wasted on an empty home. Remote control via the Nest app allows you to manage your thermostat from anywhere, adding a layer of convenience.

The Energy History feature helps you monitor and understand your energy usage, potentially leading to cost savings. Additionally, the Nest Leaf icon provides guidance on energy-efficient temperature settings. However, this thermostat does not natively integrate with Apple HomeKit, which could be a drawback for users deeply invested in the Apple ecosystem. While it works well with Google Assistant and Amazon Alexa, Apple users might need additional hardware or workarounds for HomeKit compatibility.

In terms of learning capabilities, the Nest excels with its intuitive schedule creation and geofencing features, enhancing user comfort and energy efficiency. The user interface is sleek and user-friendly, with a stainless steel design that complements modern home aesthetics. If you prioritize seamless Apple HomeKit integration, this might not be the best choice. Still, for those looking for a smart thermostat with advanced learning features and comprehensive remote control, the Google Nest Learning Thermostat is a strong contender.
