I configured two (internal) OH2 instances and experienced, that the slave installation sends all their slave items to my master Installation as intended, while the master installation also sends all items to the broker (they appear in the brokers’ log and I can subscribe to the masters’ items).
I only want the slave to send its items to the master and the master can keep its own items!
in the Master mqtt-eventbus.cfg I left the sending configuration out on purpose:
# item name which can be used for posting the received value to the event bus.
I am trying to do the same setup . would you be able to share in detail how you setup OH1 and OH2 as master and slave? I intend to have OH2 master as a openhabian in an ubuntu VM(ESXI), and OH1 slave with my z wave stick which is in another remote part of the house. Which do you setup first?
I am also more inclined to go the event bus mqtt route as MQTT has always been reliable for me, but I was informed that eventbus is not fully supported in the new MQTT 2.4 binding as yet. So not sure which way to go if I want a seamless futureproorf solution
Another method will be used to achieve a similar result with MQTTv2
It will take more configuration but you will be able to “link” two OH2 instances together in a similar (not the same) fashion as the Event-Bus integration.
