Might not be able to reuse the box since it looks like metal, which isn’t a problem for the current timer but can be a problem for the radio in the Z Wave or Zigbee device. That’s why the smartenIT devices, which are intended primarily for use with pool equipment, Have the weatherproofing that they do – – it allows you to use the relay outside of a metal box. But you can also get a plastic project box if the metal is a problem, those typically let more signal through.
There’s also the question of operating temperature range. As I mentioned, the Aeon micro is really intended for installation inside a wall, and it’s only rated for A range from 41 degrees Fahrenheit to a little over 100. In contrast, the smartenIt is rated for a range from -13 degrees Fahrenheit to 120. The GE falls in between, but can handle down to 5°F.
(And if you have it inside a metal box, it typically will get hotter in the summer.)
In general, if the device doesn’t say that it’s rated for outdoors, it probably won’t be rated to work below freezing.
The point is just that there are differences in the different models. So it’s good to look at the specs.
