Enabling MQTT or reboot with MQTT enabled -> deactivte the SM solar system

[Helmut1965]

EMS Version: 3.7.0
Board Profile: BBQKees Gateway E32, V1.5
TX Mode: EMS+, Service Key 0x0B

Devices: GB192, RC310, Solar Module SM100, WaterModule MS100

Problem Description: During the last day I try to change from the IOBroker EMS adapter to an mqtt communication. To do so, I enable MQTT in EMS-ESP. After I enable the MQTT it deactivates a few minutes later the Solar System. Modul is still available.

The entity 'activated' is set to off. I'm not able to enable this in web interface, I have to renable it in the RC310 at the device.
Also in case I reboot the EMS-ESP or I disconnet the ethernet cable, the Solar system will be disabled.
I copied a few log entries which was created during the enablement of the MQTT.
The problem is also there in case I change from ESP+ to ESP.

Is there something else what I can provide?
Have a great Day

looking at the logs I see something is sending many MQTT commands to EMS-ESP. Do you know what this could be?
