HarmonyHub Binding does not find the Hub

Hey,
I installed openhab2 on a raspberrypi. installed openhab2,which looks good.
then I installed the harmonyhub binding and was within the inbox for the hub to appear. But nothing happens.
Even if I force to search for it.
I installed then the network binding, this binding finds all devices. so it seems to work.

But why is it not working for the harmonyhub?
Can anybody help? Or at least tell me how to add the hub manually?

Thanks in advance,
TKO

Manual thing config is described in the docs:

http://docs.openhab.org/addons/bindings/harmonyhub/readme.html#thing-configuration

Make sure you have the version2 binding installed to be able to auto discover your hub:
http://docs.openhab.org/addons/bindings/harmonyhub/readme.html

Auto discovery won’t work with version1 binding:

Thx for the reply.
I guess, it it the correct version. I Installed it trhough the paperUI.

Now, I added it manually, but got the following error out of the log files:

Some time ago I’ve read about issues when the hub is connected through Access Points, Switches or whatever.
For testing, try direct connection between hub and your router …

thanks for the hint with the direct connection.
The solution was, that the hub needed to be connected to the original wifi and NOT to any guest wifi which I had setup.

Thanks.
