MQTT: diffrent Subscribe and Publish

I finaly have OpenHAB working with my MQTT system.

But the previouse app did:

  • Publish to a topic
  • the switch wil do its job and update the status to a different topic.
  • The app will show a spinning circle until the second message arrive.

This is important to know if the system works when i am remote.
Is this also posible with OpenHAB?

-> outbound messages:

-> inbound messages:

no idea.

For everything else see:
