Answer This Question

Great question. The Nest Temperature Sensor communicates with your thermostat using Bluetooth Low Energy, and it typically works well within a range of up to 50 feet, though thick walls or large obstacles between the sensor and your thermostat can affect the distance.

      Does the Nest thermostat have to actively control the temperature in the room where a sensor is placed or can the sensor solely provide the temperature of that room without any action by the thermostat?

      Answer This Question

      Great question, David. Yes, with the Nest Temperature Sensor (2nd Gen), you can view the current temperature of any sensor's room directly in the Google Home app without needing the thermostat to actively adjust the temperature for that specific room at that moment.

            Do these 2nd gen Nest temp sensors require a thermostat to track/report temperature or can they report directly to the Nest mobile app?

            Answer This Question

            Hi there, bmak. Unfortunately, you can't use a Nest Temperature Sensor without a Nest thermostat. Your temperature sensor reports temperature data directly to a Nest thermostat in the same home. Here’s an article for more information: https://support.google.com/googlenest/answer/9248154

              Do these sensors detect motion in the room, or do they strictly measure temperature?

              Answer This Question

              Thanks for your inquiry, Dave. The Nest Temperature Sensor 2nd gen only tracks the temperature — it doesn't pick up on movement.

                Great question, Brittney. The Nest Temperature Sensor lets you choose where your thermostat measures the temperature in your home to help keep you comfortable. For example, you might want a temperature sensor if you have a multi-story home. It can help your thermostat keep you comfortable on the floor you choose at any time of day.

                  Sensor works
                  I purchased this sensor to help my thermostat read better due to being on a return chase. It was easy to set up and wall mount with a simple command strip. The thermostat (not the sensor) broke shortly after and I replaced the whole system with an Ecobee which has been overall better.

                    This thing was a struggle to connect it to my second floor thermostat. It took me one day to install but I finally got it.

                      This was essential spares the inconvenience of placing a thermostat in the bedroom.

                      Works like a charm
                      I needed to heat/cool the master bedroom, so I installed this sensor. The instructions were minimal, but I figured it out. First, locate where you want the sensor, preferably on the other side of the room from the AC/heating duct. Open the sensor and write down the 9 digit alphanumeric code that is used for registration. Pull the tab that activates the battery and hang the sensor on the small screw that came in the box. No need for an anchor, just drill a pilot hole in the drywall a little smaller than the provided screw and attach to the wall. Download the Home app and begin the fun process of adding the sensor to your Nest account. Caution: after the installation is complete, the sensor will indicate a low 32 degree temperature, and “low battery”. Don’t panic, it’s temporary. After a couple minutes, the sensor will reset and show the proper temperature and “full battery”.

                        Just what we needed. This is a 3rd sensor for us, needed it for the master bedroom so the aC would stay on until this room achieved the desired temp.
