The Ecobee Smart Thermostat with Voice Control offers everything you'd want in a smart thermostat, which is why it's our top pick. Thanks to a built-in speaker and integrated Alexa and Siri, you can control the Ecobee hands-free with voice commands. You can also listen to music on the thermostat or place calls, ask questions, and control other devices via a connected smart speaker. If you don't use Siri or Alexa, this device works nicely with Google Assistant and Samsung SmartThings. You can also make temperature or schedule adjustments via the Ecobee App, even when you're not home. 

This device will learn your schedule and regulate the temperature accordingly. The Ecobee also makes recommendations based on your habits and sends alerts of anything out of the ordinary. The included SmartSensor elevates comfort in the rooms where you spend the most time. Place this sensor in a particular space, and it will make sure conditions are comfortable there and balanced throughout your home. 

This Ecobee model is a pricier option than other smart thermostats, but it offers immense value. It's hard to beat the Energy Star certification, sleek glass design, and many advanced features.

In addition, it senses when the home is empty and will adjust the home’s temperature accordingly. The Google Nest Thermostat also monitors the HVAC system and notifies you when there is a problem with the system.

If you live in an apartment or a smaller house, you may not need all of the features on the Ecobee SmartThermostat with Voice Control. The Ecobee3 Lite is a more economical option that’s still Energy Star certified to help you save on annual energy costs.

However, the thermostat is compatible with Smart Sensor, and it can be controlled with the Ecobee App. In addition, the thermostat is compatible with Alexa, Google Assistant, Apple HomeKit, and several other smart home systems.

Best for Multiple Zones: Honeywell Home T9 Smart Thermostat with Sensor

The Honeywell Home T9 Smart Thermostat with Sensor is good for controlling the temperature in multiple rooms. Each smart room sensor ensures that the temperature is right in that room—and that’s important because when you’re in the bedroom, you don’t want the temperature to be based on your empty living room. If there are multiple people in your home, you can get multiple smart room sensors to ensure that everyone’s room has a comfortable temperature. The thermostat also uses location-based geofencing to determine when the house is empty and then adjust the temperature accordingly. The thermostat works with the Honeywell App, as well as Alexa, Google Assistant, Cortana, and other voice assistants.

Best Design: Google Nest Learning Thermostat 3rd gen

In addition, it monitors the temperature in multiple zones. The thermostat is compatible with most HVAC systems and easy to install. In addition, the high-resolution display makes it easy to see the temperature from across the room. The Nest Learning Thermostat 3rd Generation Thermostat works with Alexa and Google Assistant.

Best for Apple HomeKit: Honeywell Home T5
