Thank you Wolfgang
…the first mentioned case was one I’ve created. It was slightly different from this one …but the hint with the time is something I need to watch for, but now on the side of OH (win) not Pi.
Last time I’ve restarted OH there was no issue at all …will have an eye on that.
The second mentioned case is impossible in this config because OH will get restarted with the VM where it lives …but good to know that there could be issues with two instances of OH. Is there a case where somebody wants to run two instances of OH (except for testing)?
