i personally do not think it would have any true or accurate effect in a cage enviornment you know, they are designed for climate controls in terrariums and will run everything (lights, mist machines, humidifiers, etc) on a timer and thermostate.
If you are worried about temperature controls in a screen cage, zoo med and i think r-zilla have basic thermostates that you can hook up. will shut off bask lights when temp exceeds a certain temperature, and vice versa.
