Any luck with those? I found a g9 fitting variant from LUUMR I would like to add it to the hue bridge or alternatively direct to Homey. Not much to find about those.
LUUMR is apparently based on Tuya (Wat is de Luumr app? | Lampenlicht). In the description on this (Dutch) page is says nothing about needing a hub. Only the LUMMR app would be sufficient. That leads me to the conclusion that it can only be Wifi controlled. Maybe try with the Homey Tuya app?
