Ecobee4 with Room Sensor | $180 | Woot
While not nearly as ubiquitous as Nest’s Learning Thermostats, Ecobee’s smart thermostats one-up the competition by pairing with wireless remote sensors that you can place elsewhere in your house, giving the thermostat a more accurate picture of your home’s overall temperature.
The Ecobee4 is especially notable in that it doesn’t just work with Alexa...it actually is a fully-featured Alexa device, just like an Echo Dot that lives on your wall. $180 is a solid price for something that usually sells for around $200.
