FAQ: Philips Hue and Other Smart Bulbs - What sort of light switches to use with them? (Long FAQ)

I really like the looks and reported operation of these cooper witches, but the Amazon listing specifically notes that they are NOT for LED’s and that this auxiliary requires a master switch - it is incapable of dimming without one. Can anyone with direct experience comment on this? Also, the listing simply says “RF.” Am I to conclude this is z-wave or zigbee RF, and how exactly does ST communicate with them?
EDIT: Just noticed much of the discussion of this solution got moved to a separate wiring thread, but, as this is about features and not wiring, I chose to leave this here. Please advise if y’all think I should move this. Cheers!
