The Ecobee4 Smart Thermostat is on sale for $199.00 for Black Friday. This matches the lowest price it has ever been. This is easily the most Alexa-friendly smart thermostat on the market. That’s not only because its hands-free capabilities essentially make it like having an Echo Dot on your wall, but because Amazon works closely with Ecobee, so they are always among the first 3rd-party manufacturers to gain new Alexa capabilities that get released. A nice perk of Ecobee thermostats is that they come with a remote room sensor that lets you dial in a temperature for a specific part of your house. With other smart thermostats, like Nest, you have to pay extra for room sensors. If you’re already up to your neck in Alexa devices in your home, you can save a bit of money and get the Ecobee3 Smart Thermostat on sale for $139.00, which has many of the same capabilities, minus the built-in Alexa mics and speaker. That price for the Ecobee3 is also the lowest it has ever been.
