Utility Meter reset at random time?

I have been using utility meter to track daily gas consumption fine for days. But somehow last night it decided to reset at 2:30am instead of 0:00 like usually. Logs doesn’t show anything. Nothing really change. I only updated from

  dsmr_daily_gas:
    source: sensor.gas_consumed
    cycle: daily

to include name: DSMR Daily Gas.

Any idea?
