Amazon Smart Thermostat, Thermostat only, 1 Pack, C-wire required (Amazon ASIN B08J4C8871)

With heating season coming, a smart thermostat is a practical way to keep from heating an empty house while everyone's at work or school. As of Saturday evening, Amazon has its own Smart Thermostat at $56.99, down from a $79.99 list price, shipped and sold by Amazon.com with free delivery. Amazon has it marked as a limited-time deal. It works with Alexa and Ring. Check your wiring before you order: it requires a C-wire, and older homes may need an adapter bought separately. It also only works with one Alexa account, so the household shares a single login. The listing says rebates may be available from your energy provider, so a call to your power company could take a little more off. Prices move, so confirm it in your cart.
