To expand on my quest to control my Philips wiz lights (for which I have a ton of them now). I now have dimming from a physical (as well as logical) black series dimmer (firmware 1.52 and DTH 09-09-21) working via a SmartThings WebCore piston. In SmartBulb mode and ramp rate for dimming set to 2 (this provides enough of a real-timeness to dimming changes) on the switch, my piston grabs the dimming level of the switch and then set the dim level of a group of 4 wiz lights to match. With basic scene control now in the black series, I coded up the 1x tap up to go to 100% and turn on the bulbs and 1x tap down to turn off the bulbs. So I can do (relatively, about a .25-.5s delay) instant on/off and dimming. Oh and dimming works from my GE aux switch as well as it’s all in a 3 way.
I love that my black series dimmer led bar moves with the dim level of my lights.
Pretty cool stuff. Interestingly it’s taken me almost year to get to this point (from my original post) and answer my own questions 
i know the whole smart bulb and smart switch what can/can’t you do comes up a lot and I know particuarly for the Wiz Bulbs (I’m a Philips Hue convert) comes up a lot on other forums. Hopefully this helps someone else. I plan to try this on my Red Series Dimmer and see what happens.
