A valve has two objects that need to be configured. The first is called "Active" and is sort of Open/Close. It needs a listen and set address. The Datapoint Type is 1.001
The second object is called "In Use" which means there is actually a flow (of water). If you do not have anything that represents this, use the listen address of the "Active" above. The Datapoint Type is 1.002
