Create a myopenhab.persist file. I’m not certain it is required but it is the first thing I would try. If you don’t actually want to share anything with my.openhab, you can create a gMyOpenhab group, don’t assign any Items to that Group, and in your myopenhab.persist file persist gMyOpenhab*.
but due to the fact I’m a real beginner, I don’t understand anything!
I know what persitance is, but what is supposed to be in there, when no items are assinged to that group???
Nothing is in there. My working theory is that my.openhab doesn’t actually establish the connection between your instance of openHAB and the my.openhab servers without the myopenhab.persist file. As far as I know you can’t have a persistence file without an Items section. So if you persist gMyOpenhab* that lets you create a valid myopenhab.persist file without exposing any of your Items to the my.openhab servers.
It also sets you up to be able to choose which Items DO get shared by simply adding or removing them to the gMyOpenhab group.
