Is there a workaround?

Continuing the discussion from deltaSince or historicState sometimes returns null on openHAB 3.2:

I think I have a similar problem - my water meter rule calculates hourly water usage, so I see some random null values of “current_value.historicState(now.minusHours(1))”, it works most of the time but fails every noun and then.
Can I ask if you have found a workaround to this issue?
