Nest Temperature Sensor (2nd Gen) - Room Comfort Sensor with Scheduling - Works with The Nest Learning Thermostat (3rd and 4th Gen) and Nest Thermostat E - Porcelain, White

Easy to set up and works great to keep the heat nicely balanced.

No, despite description claims it's compatible with the third generation learning thermostat it doesn't work due to software version issues, but there is no new software version available. Now need to go and investigate with Google Nest help. Painful.

If buying for use the UK, be vary wary, it is not compatible and will not link to your 3rd generation Nest thermostat as suggested in the product description.

First Impressions I picked up the Nest Temperature Sensors to pair with my Nest Learning Thermostat, and they’ve been a game-changer. No more guessing if the thermostat in the hallway is really keeping the bedroom or living room comfortable. These sensors just work. Performance Accurate readings: Each sensor keeps track of room temperature reliably—no weird swings, no lag. Scheduling: I can tell my Nest to prioritize the bedroom at night and the living room during the day. It actually feels like the system is paying attention to how I live. Seamless integration: They connected right away through the Nest app, and syncing with the thermostat was painless. Design The porcelain finish is clean and minimal. They’re small, subtle, and don’t look like clunky tech sitting around. Pros Easy setup and integration. Accurate room temperature tracking. Scheduling makes it easy to prioritize comfort where I need it. Sleek, subtle design. Cons Runs on batteries, so eventually I’ll have to swap them (not a dealbreaker). Bottom Line The Nest Temperature Sensors do exactly what they’re supposed to: make the whole system smarter, more comfortable, and more tailored to daily life.

Had it only for a few hours and its awesome, absolutely worth it. My thermostat is in a hallway, and there is an air intake underneath it and a bathroom beside it. The temp on my thermostat was never accurate and my bills were all over the place. I would constantly be adjusting it up or down at least 6 times during the day. Instead of hiring an HVAC person to run lines and cut through drywall and do all of that, chat gpt suggested that I just get a sensor. My house temp is now officially stable. Im so impressed. It showed rhat the hallway was actually 23.5 while the rooms were only 20. I cant wait to save a good amount of money because of this now that the thermostat isnt confused!
