Indeed that looks rather different from the responses the binding expect to see. I assume xiaomi introduced some new method with this device, or changed part of the request parameters (as it has the {"code":-6,"message":"invalid device","result":null}

If I find some time I'll try if I can discover what has changed .

Would be a great enhancement. Suggest to add to bountysource to hopefully have someone contribute this, as from my side it will be challenging (time & no access to a similar device) to add this functionality.
