10 Best Smart Thermostat With Humidity Control 2025 in the United States

The Google Nest Learning Thermostat (4th Gen) stands out as a top choice in the smart thermostat category, especially for those looking to manage their home's temperature and humidity efficiently. Its compatibility with various heating and cooling systems makes it versatile for most homes. The inclusion of the Nest Temperature Sensor further enhances its capability to address temperature variances in different rooms, ideal for larger spaces or homes with specific comfort needs.

One of the key strengths of this thermostat is its energy-saving features. With the ability to learn your preferences and automatically adjust temperatures, it can help save an average of 12% on heating and 15% on cooling bills. The Adaptive Eco feature is particularly valuable, as it finds energy-efficient settings based on external temperatures.

The user interface is intuitive and visually appealing, thanks to a large, bright display that adjusts for optimum visibility. Integration with smart home systems like Google Home and Alexa makes it easy to control through voice commands or the app. Installation is user-friendly, typically taking around 40 minutes, which is a plus for DIY enthusiasts.

There are a few drawbacks to consider. While the thermostat is designed to work with many systems, some users may still need a C wire for compatibility, which could complicate installation in certain setups. Additionally, while it includes humidity control features, it does not provide as detailed humidity management as some more specialized thermostats might.

The design and functionality receive high praise, though the price point may be a concern for budget-conscious buyers. Despite these minor drawbacks, the Google Nest Learning Thermostat (4th Gen) represents a solid investment for anyone looking to enhance home comfort while reducing energy costs.

Humidity control is also a noteworthy aspect, as it contributes to a more comfortable living environment, though it may not be as advanced as dedicated humidity controllers. The device's compatibility with various heating and cooling systems adds to its versatility, though it does have limitations—most notably, it does not work with electric baseboard heat.

Installation is designed to be user-friendly, with a guided setup and an alternative power adapter included. However, potential buyers should check for C-wire compatibility, as this can lead to installation challenges for some users. On the downside, some users may find the reliance on Wi-Fi connectivity to be a drawback, especially in homes with weak internet signals.
