Wait for completing 1 task (the reliable KNX Comms) and then you can add the tag
Anyway, to answer your question: tags [ "" ]
are applied after the group ()
and before the binding {}
See: HomeKit Add-on - System Integrations | openHAB
RB
The (virtual) PA of the RB (of the KNX Binding of OH2 to be more specific)
This is to identify the RB on the KNX Bus so that the KNX Binding can receive info and replies
Use 0.0.0 or another free PA on your KNX Bus
Since you know KNX & ETS: make sure that the telegrams can be routed back & forth from/to the IP world (RB) to/from the KNX Bus on your KNX/IP Router. Check with ETS this and the filter table of the KNX/IP Router.
You can use a dummy App to represent the openHAB2 system in your KNX configuration and link this PA to the GAs that you want (or allow full routing on the KNX/IP Router)
Wait We will fix this later
Ps: How to use code fences . It makes it easier to read & post logs & configs
