Usage of brightness_step

2.4.5

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?

Hi @7oku,

yes that's right brightness_step I haven't implemented in the adapter yet.
I'm looking into it, but can't tell you how long it will take me.

Please test the dev branch: https://github.com/o0shojo0o/ioBroker.zigbee2mqtt/tree/dev_%2396

Hey @o0shojo0o,

awesome, that was quite fast and works like a charm.
Closing the ticket!
