Yes, I updated my gateway firmware. I think, there is something wrong with the item type. Is is correct ? (String). In addition, in my paper UI, the channel for action is different from the others (look at the photo). There is no type and the logo is different:
I really do think that your problem doesn’t belong to the OH Binding.
Just run wireshark and see if you can detect network packages when shakeing or rotating the cube.
And you can’t see any events in the logs right?
Let me be specific. When I do any action with the Cube, the corresponding action is published to MQTT, but not on the topic that I specified ( xiaomiCube/action/state). As you know, openHAB has even bus for MQTT(look at the picture). The corresponding action (FLIP90, etc.) is published to state/publish topic.
Therefore, I am sure that there is something wrong with my items file.
