Hi. I’d like to have smooth transitions from one state (e.g. low brightness or off or red-color) to another ( high brightness, another color). Currently, that is not “built-in”. Change color/brightness will do that “immediately”. A workaround is to use OpenHab code and send a lot of http requests…

@papaPhiL,
I would sucgest to flash Tasmota on the device.
I think, Tasmota has this feature.
