I believe the problem occurs as a result of NaN data,

I’ve noticed the same behavior and could associate it with NaN values as well:

Wh accumulator - strange behavior

That’s definitely best practice and should also be in the official guide. My emonpi was accidentally without power for some days, which is not a big problem as the emonTh continues to increment the pulses. Once the Pi was back online, the wh_accumulator did a bad job: [16] For any reason (probably because the wh_accumulator needs also the elapsed time for the calculation), it did’t count the 1971 pulses and it just shows a horizontal line. However “Total pulse count to pulse increment” worke…
