Thank you for the quick response, I have installed the beta version now 
And will check if behaves better.
Before updating I was looking in this topic on any updates regarding the DESS algorithm.
But could not find any other than:
v3.60~47
Dynamic ESS
* Improve how Dynamic ESS reacts when actual consumption or solar production differs from forecasted. For example when there is more solar then expected, the updated algorithm will in many cases use that extra solar power to charge the battery, even if that would exceed the planned SOC level for the current hour. Instead of feeding that excess solar back into the grid for a low price, to later have to buy it back at a higher price.
Guess many under the hood changes are not mentioned in the changelog? Or did I miss this?
