#Per-appliance gas/water measurement?

I haven't had much luck with internet searches for these; majority of the results focus on whole-home water measurement and diagnostics.

Does anyone have any notions/cautions/resources for trying to track gas and water usage by appliance?

Unless you are having dedicated meters for them, you will be having a hard or expensive time getting accurate results

Some devices that consume a fixed flow rate can easily be tracked by only knowing their on/off state.

For example I only measure gas consumption at my gas meter, but I can see how much my furnace consumes by looking at the change in flow rate when it is turned on, or by confirming nothing else in the house is using gas. And so it is trivial to create a template sensor that is e.g. 5.1 cfm when the climate entity’s hvac_action is heating, and zero in all other cases. Then a Riemann sum helper to track the usage based off that template sensor.

This works great for a gas fireplace, a furnace, a gas water heater, etc. But not useful for a clothes dryer, gas range, etc.

I have a followup question about what you just said @old turtle .... I've done something similar, but I chose to convert all of my gas measurements (both meter and estimated furnace consumption) in kW to make it easy to compare energy sources. The Energy dashboard explicitly supports both methods (gas volume or energy content). But now when I go to add my furnace consumption entity to the Energy dashboard, how can I tell it this is a Gas consumer, not an Electricity consumer?

(maybe I should start a new thread on this, sorry)

Ah, thanks.
