Click for Philips Hue (RunLessWire Switch)
by Mike R.
Not cheap, but it might be exactly what you need
Used these switches in concert with hue bulbs to get smart lighting where no neutral wire was available. It also allowed me to switch a hue bulb in a lamp in one room and change scenes in another as an added bonus. They’re not cheap, but they are responsive and work great. I’ll probably buy more. It’s more responsive than using a z-wave switch with the internal relay bypassed to switch the hue through a smart hub with hue integration.
