What is missing or not working
According to the docs for ikea/hue bulbs we should be able to use brightness_step attribute to control brightness in a given step of an integer (either up like 40 or down with -40) through zigbee2mqtt. I would expect there to be an object in the object browser of iobroker, just like we find brightness and brightness_move here.
Is that object missing and/or is that supposed to be utilized in another way?
