Filter sproadic 0-values of the Tasmota electricity meter

I frequently receive 0 values from my Tasmota reading head for my electricity meter.
I have already created an issue and hope for an improvement soon: Tasmota Issue

Until then, however, I am looking for a way to prevent these false 0 values from being accepted in Home Assistant in the first place. One can assume that an electricity meter will never have a reading of 0.

I have not made use of the utility meter integration. Is this the right approach, or is there a smarter way?
