Unfortunately this isnt fixed after the update. In fact, I think there's something wrong with the driver itself. I think this is why I switched the Brian Copland driver at one point...but this really has to get fixed.
So I do still have the issue with toggling coming back to the wrong color....but also..
The parent device will affect the child devices. For instance....if the parent device somehow gets set to 50 (I dont even know how this could happen, I dont have any rules associated with it), then the child "Device_Color" will never go above 50 no matter what you do.
Similar things happens with "Blue Level", "green level" on the parent device.
I think Hubitat needs to decide:
If you're doing to do child-device model...there should be no color settings in the parent.
I dont even know why there are child devices...what is the purpose?
