BSB-LAN setting parameters via MQTT/ EePROM Limits

Hi,
I am using the BSB Lan Adapter and it’s perfect to optimize the heating cycle and settings. But now I am considering setting different comfort temperatures during the day.
How can I identify, which values coming via MQTT payload, are being written to the Eeprom?
The problem is that the Eeprom has -as I have heared- a limited writing capability.

Thanks Jörg
