Sorry for the confusion. Only the GE Z-Wave In-Wall Switches fixed my Z-Wave repeating problem. The Aeon Labs Aeotec Z-Wave Smart Switch was advertised as a Z-Wave Repeater, but it did not help with repeating. The WeMo Insight switches are not Z-Wave so could not help my Z-Wave Repeating problem.
I did need some additional outlet switches for something else, and was planning to buy WeMo Insight switches since I have some already and liked them, but I bought the Aeon Labs Aeotec Z-Wave Smart Switches instead thinking that they would help with Z-Wave repeating, but it didn’t help. So my comment was if I had known that they won’t help, I would not have bought them and would have bought WeMo instead.
One thing I did not confirm was whether I needed BOTH the GE Z-Wave In-Wall Switches AND the Aeon Z-Wave Smart Switches to fix my Z-Wave repeating problem. I had not unplugged the smart switches from my network. I only know that with only the Aeon Smart Switches, my Z-Wave repeating problem was not solved.
