Does you KNXv2 binding work ok? (forget the rule for a moment and check if simple things work)

I think that you have more general problems that you need to address to improve the stability of your OH2 installation on Windows.

Try to make sure that the system is stable first before you start implementing rules.

stable = startup and basic operations without any errors and/or warnings in your logs.
