Ecobee3 Lite, $160 | Ecobee4, $239

Update: Both of the models on Amazon are sold out, but eBay has the Ecoobee3 for $148 when you use the code P20MEMDAY.

While they don’t have the brand recognition of Nest’s learning Thermostat, Ecobee’s smart thermostats one-up their most popular competitor by pairing with wireless remote sensors that you can place elsewhere in your house, giving them a more accurate picture of your home’s overall temperature. Plus, they work with Siri and Alexa, and the new Ecobee4 actually has Alexa built-in, meaning it’s basically an extra Echo Dot on your wall.

Both the new Ecobee4 and Ecobee3 Lite (which doesn’t come with remote sensors, though you can add them separately) are $10 off right now, the best discounts we’ve seen so far on the new models.
