Issue: heat_amount_heating unusual spikes

[Crashman1983]

Hi,

as you can see in the picture below, I've got an unusual spike in sensor.luxtronik_*****_heat_amount_heating.

It is rising when heating starts and after heating stopped, it is set back to an earlier value. That behavior is a problem to my utility meters.

I'm not sure why this happens, but it is not the first time.
