I am looking to install an exhaust fan for my garage. I want the fan to come on when the outside temperature is lower than the inside temperature. Once the inside and outside temperatures are equal, the fan should turn off.
Ideally, the controller would be WiFi capable, and allow a threshold for temperature differences, e.g. if inside and outside temps are within 2 degrees, do nothing.
Is there an InkBird product that fulfills this requirement, or comes close? Other suggestions?
