Fibaro RGBW Controller and SmartThings - cannot get it to work





I've got a Samsung Smartthings WiFi hub and I'm trying to add an RGBW LED strip via the Fibaro RGBW Controller model FGRGBWM-441.


I've tried using the default FIbaro RGBW Controller device type in Smartthings.  Then, after reading some forum articles, I added the Device Handler created by richb1 on github (

In both cases, the LED strip lights and flashes a few times (both the white channel as well as a greenish hue on the RGB LEDs.  Then it shuts off and I get an error message:  "A network or server error has a occurred. Try again later" on my SmartThings app (on a Samsung Galaxy Note 9 smartphone).  The two devices are next to me less than one meter apart.  I've excluded and then re-added the Fibaro controller a number of times, but for the life of me I cannot get this to work.


I've tried two different ways of physically connecting the Fibaro controller to the LED strip - one as pictured on the instructions (with the four "In" pins being tied to Ground) and I've also tried it without the "In" pins being connected.  Same result in both cases.


I got a cheaper German-designed RGBW ZigBee controller to work out of the box the first time with this same LED RGBW strip - one would think getting a Fibaro to work with SmartThings would be simpler than this.


I'm open to any suggestions the community might have!

  • Update:   I figured out the primary issue - my power supply appears not to have delivered enough power for the Fibaro (I didn’t even think to check this as it works fine for the 3A Nue ZigBee controller). Anyway, changed to a different power supply it it appears to be working fine - EXCEPT the fact that I cannot find a way to get the white LEDs to light now at all. I can generate “white” using the RGB LEDs, but that kind of defeats the purpose. I’m also still getting the same error message when I use the app.
