New setup Vaillant ecotec plus + VRS560 solar controller - various errors / help wanted

[gwaitsi]

I have German ecotec plus + vrs560 solar controller (they are connected together via the C1/C2 wires between both).
I just installed Daniel Kucera's ebus-to-wifi v6.3
I am connecting to HAOS 25.09
In MQTT, I see the following devices;

• ebusd Broadcast (outdoor temp sensor by the looks of it)
• ebusd bai (appears to be the ecotec plus)
• ebusd 470 (appears to be vrs560)
• ebusd (shows the running, scan, signal, uptime status) - also shows update available even though i have 25.1

I see the below errors in the logs.

Is there some guide or can someone guide me on how to optimize please
