10 Best Smart Thermostat With Humidity Control 2026 in the United States

The ecobee New Smart Thermostat Premium stands out in the smart thermostat market, especially for users seeking effective humidity control and energy savings. One of its big advantages is the SmartSensor, which helps manage temperature and eliminate hot or cold spots, enhancing comfort across rooms. It also boasts a built-in air quality monitor that not only alerts users to poor air quality but also offers actionable tips for improvement.

In terms of compatibility, this thermostat works with various smart home systems, including Apple HomeKit, Amazon Alexa, and Google Assistant, making it flexible for users with different setups. The vibrant display and user-friendly interface are further positives, making it easy to navigate and control.

However, there are some drawbacks. The need for an Apple Home Hub to enable Siri can limit its appeal for non-Apple users. Additionally, certain advanced features, like alerts for open doors or windows, require a subscription to the ecobee Smart Security plan, which may deter budget-conscious users. While the device is compatible with most HVAC systems, installation can still be challenging for those without a C-Wire, despite the included Power Extender Kit. The ecobee Smart Thermostat Premium is a great choice for tech-savvy users looking to optimize their home’s heating and cooling while maintaining good air quality, but it may pose challenges for those less familiar with smart home setups or those looking for a more budget-friendly option.

The Honeywell Home X8S Smart Thermostat is a strong choice if you want a thermostat that goes beyond just temperature control. It offers good compatibility with many heating and cooling systems, including heat pumps and conventional setups, although it does not support electric baseboard heating. One standout feature is its built-in humidity and ventilation control, helping maintain better indoor air quality, which is a bit rare in smart thermostats. The included wireless Room Sensor improves comfort by allowing targeted temperature adjustments in different rooms and has a long range for flexible placement. Its 5-inch customizable touchscreen is easy to read and lets you personalize colors and styles to fit your home’s look.

For smart home fans, it works well with Alexa, Google Assistant, Apple Home, and is Matter certified, making it easy to integrate with many devices. The ability to see and talk to visitors on compatible video doorbells right from the thermostat adds useful convenience, especially for home security. Remote control through the First Alert app means you can manage settings from anywhere. It also includes energy-saving features, supports programs and rebates, and comes ENERGY STAR certified.

Some advanced air quality features require additional HVAC equipment, so you might need extra gear to get the full benefit. It also requires a C-wire for installation, though the package includes a voucher for an adapter if needed. Learning capabilities are handled through occupancy and presence detection rather than traditional adaptive scheduling, which works well but might not suit everyone looking for a fully self-learning thermostat. This thermostat is well-suited for users wanting a smart, connected device with strong humidity control and air quality features, combined with useful extras like video doorbell integration and flexible room sensing.

The Honeywell Home T9 WiFi Smart Thermostat is a solid choice for those looking to enhance their home comfort while managing energy efficiency. One of its standout features is the Smart Room Sensor, which allows you to adjust temperatures in multiple rooms, ensuring comfort exactly where you need it. The thermostat offers impressive connectivity options, supporting integration with Amazon Alexa, Apple HomeKit, Google Assistant, and other smart home systems, making it easy to control through voice commands or the Resideo app. Its learning capabilities help adapt to your schedule, promoting energy savings, and it provides energy reports to help you keep track of your usage.

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. While the battery-powered smart sensors offer flexibility, they require regular battery replacements, which can be an inconvenience. This thermostat is well-suited for those looking to automate their heating and cooling and benefit from humidity control, provided they are aware of its limitations and installation requirements.
