[SOLVED] Eclipse IoT Marketplace Issue

Hey all,

I would like to install the following addon via the eclipse market place:
https://marketplace.eclipse.org/content/openhab-xiaomi-vacuum-binding#undefined

It is usable for the Xiaomi Vacuum Robots.
But unfortunately, I cannot see this addon vial the installed eclipse addons ion the bindings sections in Openhab, reason is unclear for me. See the following picture:

I tried to install the addon via drag and drop from the Eclipse Market place via the above mentioned link, but then i receive the following log file entry:

==> /var/log/openhab2/openhab.log <==

2018-09-25 21:07:01.715 [ERROR] [nternal.extensions.ExtensionResource] - Exception while installing extension: No extension service registered for market:binding-3499123

2018-09-25 21:07:01.722 [thome.event.ExtensionEvent] - market:binding-3499123: No extension service registered for market:binding-3499123

Any ideas?
