Thanks for the big update.

I added some comments, note that quite a few of them should be applied in a general way. I did not yet review the complete code but I think that I have a good view of what changed and hope that you can improve the pull request given the pointers I gave you.

If you have any questions or if you finished please ping me.

You don't have to call toString it will be called automatically, but only when the logging-level actually applies.

Please apply everywhere.

Note that this does not have to be error logging anymore because you already configured the thing status, it more likely that he will see that than that he will the error log.

This method looks to have a lot of repetition, can you implement this in smarter way?

The "problem" is that I need to check every parameter, to be able to log a precise error.
All the repetetive assignments removed.

Why OFFLINE, you are even connecting, maybe UNKNOW would be more suitable?

Nope, at that specific place I have verified that config in openHAB looks good, Now I have to verify the configuration in the ZoneMidner Server, which could also be wrong (eg. impossible to establish connection). The only way to find out is trial and error .... :-(. I will add a few comments in the code :-)

Yes, but OFFLINE should not purely be about the connection but more about the state of the Thing to which you are connecting, so we don't know yet, but stating OFFLINE is premature.

If this method is not a setter, which is suggested by the number of exceptions it throws, it might be better to call it disconnect. Because now it confuse me as the reader
