As for other devices this attribute for MySensors devices too, including MysensorsMulti.
Attribute 'discrete' for MySensors devices
@mwittig Sorry, I do not understand what to do. I describe my problem more concrete:
I have a MySensorsMulti device with a integer typed sensor as attribute. This sensor I would like to display as discrete in the graph. Directly there is no option for it. Should I crete a filter device only for making it discrete? The filtering itself is not needed in my case.
