Change of controller role

[RolfKunkel]

Thank you very much for your helpful comments.

Meanwhile I succeeded to restore my system

using an older zab backup file that I saved before I introduced a secondary controller

using an older Razberry controller

because I did not succeed to reset the Razberry 7 Pro controller via the GUI.

I ordered a new Raspberry Pi board to have one as spare. I will use the spare PI to test if I can reset the 7 Pro Razberry controller using the alternative way without GUI. And definitely I will never implement a secondary controller. Lesson learned.

Make sure the Razberry board has the latest firmware updates. My spare is at the current firmware level.
