Ecobee4 Thermostat With Voice | $169 | Amazon
While it doesn’t have the brand recognition of Nest’s learning Thermostat, the Ecobee4 Smart Thermostat one-ups its most popular competitor 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. Plus, it’ll work with Siri via HomeKit, and your Amazon Echo too.
Today’s $169 price tag is the lowest Amazon’s ever listed, and would be unprecedented if not for an out-of-the-blue $150 sale from Target a few months ago.
