I picked up the Leviton Decora switch today at home depot in the wink section. It is Z-wave compatible as it says on the package "compatible with all zwave hubs"... and technically it is, but instead of an on/off option on the almond+, it has "Get" and "Set" buttons plus a status box next to the "get" button and at +/- option surrounding a box that goes from 0 to 255 next to the set button. The cloud and iOS interfaces show "unsupported sensor". When I "set" to 0 it turns the lights off, when I "set" 255 it turns the lights on.
It is NOT a dimmer switch, just on/off. I am still running the firmware 0067, if that makes a difference.
