From what i can find on the Fibaro forum and reading around, there appears to be no proper Fibaro RGBW controler in the new smartthings app, Codersaur who wrote the DTH for the classic app is no longer active so no chance of that getting ported over
I have led lights round my sofits externaly controled by a 441 Fib RGBW controler, worried now after the classic app and back end is killed off, will i no longer have control
