Add Upstream meters for Water Consumption in Energy dashboard

[Benon-user]

In my house I have also 2 water meters that are nested.
In my country the typical solution from water supply companies is to install additional sub counter for garden which is a downstream meter of the main water counter. Then I don’t pay for sewage disposal for the amount of water I use for garden.
I got integrated both the meters in my HA but now the Total water consumption is over calculated.
Please add upstream device feature for water counters similar to energy meters, like in this topic

WTH does Energy Dashboard not support nesting energy sensors?

I just started using energy metering about a month ago and it has been amazingly useful. This is one issue that I think could be solved fairly easily. Description: I have CT clamps measuring many circuits in my home, including the entire garage. In the garage I have a car charger that provides energy metering. With this setup, electricity consumption when I charge my car is counted by both sensors. I would like HA to track both, but it needs to understand that the car charger is a sub-meter to…
