With sweater weather in the forecast, Google’s Nest Learning Thermostat (4th generation) is on sale for $219.99 in all three colors at major retailers. The price matches its best price of the year and is close to its all-time low. The thermostat is designed to learn heating and cooling preferences, auto-create schedules, and suggest changes to save energy, including automatic adjustments when occupants are away. It includes a remote temperature sensor in the box to help balance temperature across rooms and supports a wide range of HVAC systems and humidification/dehumidification equipment. The device is Matter-ready and generally does not require a C-wire, though using one can help maintain power in some installations. In addition to the thermostat deal, the article notes a Casio WS-B1000 retro step-tracking watch for about $24 and a four-pack of Apple AirTags for $69.99, listing these as additional savings for shoppers.
