Describe the issue you are experiencing
Hello
In my opinion there is a bug.
Under "Individual water devices" I set up a simple relationship between the main water supply, the sub-meter for the heater, and the end-water meter:
“Main ZW Wifi” → “Zw->CWU Sub” → “4 CWU”
After that, I see a red-marked branch in the flow diagram:
However, when I also add the end-water device (in my case named "4 CWU") to the "Water consumption" section, nothing is displayed under "Water Flow" but I see the meter under "Water consumption" & "Sources" table.
Describe the behavior you expected
I should see my configured water meter parallel under sections "Individual water devices" and "Water consumption" & "Sources" table.
