Support for EARTH unit on a PbHUB?
- 
					
					
					
					
 Is there a technical reason that the EARTH unit cannot be connected via a PbHUB? Or is it just not set up within UIFLOW 2? If the latter is the case, then are the settings/capabilities for units extensible? (EDIT: I am of course referring to support in Blockly).

 @montanaman 
 Generally speaking, this situation is because the UiFlow2 driver does not support this Unit

 @kuriko So you are saying it is a software issue rather than hardware which seems to be the case to me. It would be really helpful to have access to the source for the unit classes so I could add functionality through inheritance.
