Amazon is currently offering the ecobee4 Alexa-Enabled Thermostat with Sensor for just $199 plus free shipping. That's $50 off the retail price and is the best deal we could find on this smart thermostat. Expires soon.

Probably the most advanced and helpful thermostat there is to date is the ecobee4 Thermostat, but it's more than just a thermostat. Firstly, this Alexa-enabled thermostat comes with additional room sensors that help you manage the cold and hot spots in your house. Most thermostats only measure the temperature of a single room, making the temperature in other spots of the house a bit odd. 

The ecobee4 comes with a sensor to make the temperature uniform all over, making you comfortable wherever you are in the room. Next, it can actually fulfill your commands through Alexa. For instance, you can set a timer, ask for a recipe, and add items to your grocery lists. It also has an embedded microphone and a speaker so you can speak to it from across the room. 

Best Features:

• Comes with room sensors that manage hot and cold spots
• Built-in Amazon Alexa Voice Service
• Fulfills your voice requests: order groceries, read the news, etc.
• Has a speaker and microphone

Overall, the ecobee4 has scored a 4.1-star rating on Amazon. According to users, ecobee did a pretty amazing job with the upgrade even if the Alexa capabilities could be limited. It does a great job on keeping the room temperature comfortable all over the room.
