I've found a few old threads about using timer switches for pool lights, but I'd like to take it a step further and replace my existing switch with a WeMo switch. My filter (and the pool light switch) are in a dark corner of the yard that no one but me likes to walk over to at night, so I'm trying to make it easy to automate the light and turn it on without walking across the yard.
I already have another WeMo switch controlling the lights for my pool bar, which is about the same distance from the house, and it works flawlessly. My question is if anyone has already tried this. I'm thinking the metal housing for the pool light switch may interfere with the wifi signal. I have already seen that metal face plates will severely limit the Wemo's range, so I planned to replace the metal cover with one of these.
