I have an Edge driver for LIFX here: GitHub - bcandersen/lifx-st-edge: LIFX driver for the SmartThings Edge platform
It’s been a while since I’ve ran it. May require some updates if there’s been any breaking API changes.
Also, TP-Link driver here for those interested: GitHub - bcandersen/tplink-st-edge: TP-Link Driver For SmartThings Edge Platform
