Zwave plug switching amps for multiroom

I am planning on using zwave mains switches to switch these amps on

With in ceiling speakers. These will be connected to a Sonos Connect. (There are only 2 of us in the house, and don’t need individual sonos for each room, bathroom, bedroom, office)

Anyone done something similar?

Tested it with a wemo switch and it’s popping on power off…but was wondering if anyone has had any long term problems with the setup?
