I have a sensor for my Nest thermostat that is somewhere in my home. It was installed and linked with my thermostat several years ago, and still shows on my app.
The problem is that I cannot find it. . . I think a houseguest may have moved it at some point? I have looked everywhere and have absolutely no clue where it might be.
Does anyone have any suggestions for how I could find it? I tried running a heater in several different rooms with the door closed to see if the temperature from the sensor changed, but I was unsuccessful.
