Amazon has discounted the ecobee4 Smart Thermostat today, bringing the price down to just $209. That is good for $40 off of its regular price and that also brings it back down to its all-time lowest price - something that hasn't been seen for a few months now.
The ecobee4 is the latest smart thermostat from the company, and it also includes Alexa built-in. While its earlier models - like the very popular ecobee3 - had Alexa compatibility, the ecobee4 actually has Alexa built-in, so it could replace your Echo device. It means that you can also ask your thermostat to turn on the lights in your home, or how the weather is today and then have the thermostat adjust the temperature before you leave for work. It's a pretty neat feature, but the ecobee4 will also work to save you money on heating and cooling your home. The ecobee4 will adjust the temperature of your home, so it stays the same temperature and it's not too hot or too cold. This is going to allow you to conserve energy and spend less each month on your energy bill. The ecobee4 does come with one sensor (though you can buy more) which allows the thermostat to know the temperature in other rooms - this is particularly useful if you have a larger home.
