Riemann sum integral of precipitation - need to reset to specific value

Use a utility meter to follow the Riemann sum sensor.

The daily cycle option will reset the utility meter at midnight.

Or you can use an automation with a time trigger to call the utility meter calibrate service any time you want. “Calibrate” it to zero.

Or if you use tariffs (night and day for example) you can use the automation and the utility meter reset service.

Or you can use the cron reset option to match any cron pattern to reset the meter.
