Hello @HarriedeGroot  
would it be possible to add additional states to exported capabilities?

Example:  
I export meter\_water and meter\_gas and want to use it in HA for energy dashboard.  
But these entities can only be added if they have attributes like:  
device\_class: gas  
state\_class: total\_increasing

The Hub only seems to export friendly\_name and unit, but nothing capability based.  
Do you think this could be added to device.\_publishMessage()? I could add some cases if you want and create PR. Or is there a better way? An alternative could be to add attributes to for devices in app settings, but this would need more adjustments.

Edit:  
I just added a template sensor to HA which inlo takes the value from the Mqtt sensor and added device\_class and state\_class.
