Sounds similar to this issue for which I have not found the solution yet. I see color wheels working fine in other handlers though. I just have not been able to determine if there’s a bug in the platform or the handler. > [@\[RELEASE\] Fibaro RGBW Controller (FGRGBWM-441) - Advanced DTH](https://community.smartthings.com/t/release-fibaro-rgbw-controller-fgrgbwm-441-advanced-dth/84784/57): > > I have this set-up and configured, Everything seems to be good except if I select the color wheel from the main tile the ST app crashes. This is on iOS (both iPad and iPhone), Is this a known issue with the handler? TIA EDIT: I did not read throughly enough. Someone else has pointed this out above already.

It appears I forgot to create a thread for this, so here it is: An advanced device handler for the Fibaro RGBW Controller, with support for changing all parameters and use of channels as inputs. Key features in v0.03: Z-Wave parameters can be configured using the SmartThings GUI. Device associations can be configured using the SmartThings GUI. Support for using the channels in a mixture of IN/OUT modes (i.e. support for analog input sensors)! No more glitches (as sending commands and receiving reports is done properly!) wink“Energy Meter”, “Power Meter”, and “Polling” capabilities fully implemented.
