KNX <-> MQTT <-> Domoticz

[emme]

Ciao,

in the process of trying to find out a way to let KNX bus talk to domoticz I'm getting some troubles in message loops:

SCENARIO 1: KNX SWITCH with a KNX ACTUATOR and a VIRTUAL SWITCH IN DOMOTICZ
- KNX send a write (event) telegram that the actuator has been sets to ON
- a NodeRed Function convert such telegram into a Dz MQTT telegram
- Domoticz MQTT telegram is recognized and processed (switch status updated)
Same scenario, different action
- Domoticz send an event telegram that the virtual switch has been sets to ON
- a NodeRed Function convert such telegram into a KNX telegram
- KNX telegram is recognized and processed (activate the switch)

BUT... the KNX event will generate a telegram... so the loop is under the way...
I'm trying to put a RBE node on the domoticz side, that works most often, but it is not enough

how could you solve this?
