Is the Nest Thermostat compatible with the Nest Temperature Sensor?
Best answer: No. As feature-laden as the Nest Thermostat is, it's not compatible with the Nest Temperature Sensor. If you want to use the sensor, you must have either a 3rd generation Nest Learning Thermostat or a Nest Thermostat E. Each of these thermostats can be paired with up to six temperature sensors. Google Nest Thermostat: Plenty of features, but still an entry-level device  Launched in October last year, Google's Nest Thermostat is arguably one of the best smart home gadgets available in the market right now. The smart thermostat sports a sleek and modern design, complete with a mirror-finished front panel and convenient side-mounted touch controls. You also get goodies like customizable heating/cooling schedules, easy control via the Google Home app, as well as the ability to monitor your home's HVAC system and, if needed, send maintenance alerts, all at an affordable price. However, being an entry-level model, the Nest Thermostat lacks features that its pricier siblings (e.g., Nest Learning Thermostat) come with. One such feature is compatibility with Google's Nest Temperature Sensor. The Nest Thermostat primarily relies on its onboard temperature sensor to control the heating and cooling in your home. While this system generally works well, it doesn't take into account subtle temperature variations among different rooms. So if the thermostat is installed in a room that's different from the one you and your family spend most of their time, you may not get the desired results. This is where something like the Nest Temperature Sensor comes into the picture. Being a standalone device, it can measure the temperature in a room/location of your choice, even if the thermostat isn't installed there. This information is then transmitted directly to the thermostat, provided it's compatible, allowing for a better adjustment of your home's HVAC system. If you want to use the Nest Temperature Sensor, you must have a 3rd generation Nest Learning Thermostat, which is still one of the best smart thermostats available out there. The sensor is also compatible with Nest Thermostat E, but Google has all but discontinued that model, so it may not be easy to get your hands on one. You can pair up to six temperature sensors with each compatible thermostat. Furthermore, a home may have up to three such thermostats for a total of up to eighteen temperature sensors. The Nest Temperature Sensor is a fairly basic device. It simply measures the temperature of the room/location it's installed and sends that data (over Bluetooth) to a 3rd generation Nest Learning Thermostat or a Nest Thermostat E.  Since multiple sensors can be paired to a thermostat, you can use the Nest app to configure the sensor that the thermostat should use as the source of temperature data.
