What is this device? (Located on wall inside a house)
Hi everyone,
would anyone know what kind of device that is? Is it an AC remote? A humidity sensor? An air quality measurement? Or just a digital temperature sensor?
The picture is from the wall of a newly built house in Arkansas, so I suspect it has to do something with "smart home".
Not necessarily true! If your home already has a thermostat, then nest has a website where you answer some questions and they let you know if it can be replaced with a thermostat. Only 4 wires are needed typically.
I've seen AC temperature controllers in this form factor. The outer ring can spin and will let you turn the temperature up or down. It is usually part of a larger smart-home system but it doesn't have to be.
