Good wireless light switch

Anyone have a recommendation of a wireless light switch I can stick on the wall to use with smart things, preferably one with multiple switches on a single panel

I think I just answered you in a different thread, but see the buttons FAQ. It lists the devices that have been tested by the community to work with SmartThings. It has mostly battery operated devices with a few mains powered ones, both wall mount and handheld types. You should find several options there ( this is a clickable link)
