Mqtt Port change

Hi.

I’m new in the Nuki Things, but Not new in IoBroker and Smarthome Things.

I have troubles to get my Nuki in Mqtt.
I use the Sonoff Adapter in IoBroker and round about 60 Sensors/Actors Works great with it.

In the Sonoff Adapter Shows Nuki only one Objekt: alive with Status true. So Connection is good.

I tried a other Mqtt Broker and the Nuki Shows all states and i’m able to lock/unlock.

But I can use the Port 1883 only in one instance, the Sonoff or the Mqtt Broker.

My Options to get the Sonoff and the Mqtt Broker both to Work:
1: migrate all my Things from Sonoff to MqttBroker. Then i Had Update all my Scripts to get them Work.

2: change Ports in Sonoff Adapter and the Ports in all my Aktors/Sensors

The simplest way is when i could Change the Nuki Mqtt Port to a other Port as 1883.
Is there a way or a Chance to Change it?

Thanks for your help

I found a simple Solution, without porting my Sonoff new.

I used a esp32 with NukiHub und bound this with a other Port via Mqtt in my Broker.

Cheap and easy.
