When running mirobo info I get the following error:

If it is a vacuum without cloud connectivity, this is expected. However, the error message could be better in that case and it should be fixed.

[reinerh]

Yes, it's a vacuum with no internet connectivity.

Ok, there's really nothing we can do for that, expect handle the error better (and inform the user that it's not going to work in those cases. Let's keep this open until that's done, thanks!
