I plugged my WM100 in an outlet behind my easy chair. I didn't want to plug it in in my man cave in the basement (formerly called my office). Because I didn't want to run up and down the stairs resetting, unplugging, reprogramming, re-syncing, testing..... and repeating. But I already knew where the best place to plug the WM100 would be. The place (plug/outlet) close to my passive phase coupler.
I had printed out a chart of the house/unit codes of the modules, switches, and macro triggers I actively control. I had downloaded the X10 app. I had waited long enough for my frozen mail delivery to thaw and warm to room temperature.
I followed the simple directions, I waited while the unit and my phones app updated. Entered the Names, House and Unit codes. I had to change some names to get at, or under the 18 space limit. I stopped in the middle of the process to test some lights.... they worked as if I was using any other remote. My setup was entered within minutes. I tested every module and all worked flawlessly from everywhere.
I added a timer... I used my phone to turn ON some X10 lights while out with my wife that evening. Everything works... out of the box... on the first try.
