I don’t know if it’s right, but I read in another thread that having two channel links to the device could cause problems (deadlock), so I went away from 3 channels and only have my Color linked now. Color will do Dimmer and Switch functions, so you only need one Channel. I also create my items in a file, so I removed what are your two Dimmer lines for each bulb. Things seem more stable for me. In the group designation, you can send the command to your ColorLight group. The other two don’t seem to have groups defined so they wouldn’t be controllable that way.
Color Bulb_J_C "J Bed Rm Clr" <colorwheel> (SW_UF_Lights,gKidsLights,gRGB)
Color Bulb_L_C "L Bed Rm Clr" <colorwheel> (SW_UF_Lights,gKidsLights,gRGB)
So I can send the command to either the Item name (Bulb_BR_C) or Group (gKidsLights).
you can also issue dimmer percentages without the color values. So I dim the lights over time and simply pass the Color Channel items a dimmer number between 99 -1.
Then turn them off with the OFF command.
So the bottom line is that these guys are brilliant @chris, you just have to pass HSB, percents, or ON/OFF to the one channel and it works.
This needs to get blessed and written up in the Wiki because I chased it for the better part of a day.
