Hello, would anyone know if the units can be used outdoors? It would not be directly exposed to the weather. I would connect it in a concrete garage, but it is open during the day when I am at work and since the garage is not attached to the house, it is of course not heated. So in the summer it can get up to 30 degrees in there and in the winter it can get down to minus temperatures. The socket is directly connected to the basement, so the 2 devices would be on the same power cable.
