The ecobee3 Smarter Wi-Fi Thermostat is currently seeing a pretty low price over on eBay. They are offering up a brand new model for just $99, which is a pretty good price. Considering this same model (2nd generation with remote sensor) is selling on Amazon for $245, that's more than half off of the regular price, pretty tough to top that right about now.
Like the Nest Learning Thermostat, the ecobee3 can be controlled from your smartphone, due to it being connected over Wi-Fi. Another important aspect of the ecobee3 is the fact that it works with Amazon's Alexa. Effectively allowing you to use your voice to control the temperature of your home. This is a pretty cool and nice feature to have. Imagine laying in bed at night and you're feeling cold, you can just shout at Alexa to adjust the temperature without getting out of bed. Pretty neat, eh? This ecobee3 Smarter Wi-Fi Thermostat comes with a three-year warranty and it is a brand new thermostat, not a refurbished or used one. It's also their latest version of their thermostat, so you're not buying an older model.
It's unclear how many of these ecobee3 Smarter Wi-Fi Thermostats are available on eBay, but it likely isn't many, so you'll want to pick one up before they are sold out. Which you can do so using the link below.
