Retroactive Data into Utility Meter?

I added an irrigation water meter to my home this month and have managed to start collecting data from it using an SDR and RTL_433. So that’s good. And I have it feeding into Home Assistant then into a Utility Meter helper. So all good there, with one hiccup. I want one of my meters to track usage monthly, but I’m already into my month. Is there a way to back-feed or offset the total into the system? I’m in a unique position as I literally started from zero this month so I could do the math pretty easily to retrofit the usage up until now if there is a way.

There’s a calibrate service for the utility meter that allows you to adjust its value.

You can run this in Developer Tools → Services.

Perfect! That worked great!
