Multiple binding configurations per item / Forward data from other bindings to another Binding

Hi!

In the documentation I do not find anything that talks about the details on how to add multiple binding configurations to an item.

The old docs give an example for Onewire and KNX:
https://github.com/openhab/openhab1-addons/wiki/KNX-Binding#bind-items-to-knx

Can anybody give some details about the possibilities, limits, the syntax and so on.
Is this still valid for OH2?

Basically, I am interested in forwarding data from other bindings like Homematic to KNX and vice versa.

It works the same way. Just separate each binding config/“channel” by a comma. Use autoupdate=false if you need to.

Personally I don’t do this. I write a rule. But in my case I never have a case where I just want to forward a command from one binding to another molested. And to transform, add to, or take away I need a rule.
