1st own ebusd experiences - questions about unknown cmds and VR921

[Commifreak]

Hi :)

Iam finally able to run ebusd with my ebusd Adapter 3.0 and my Vaillant ecoCOMPACT VSC 206-90, VRC700 and VR921 gateway.

2023-05-31 20:02:16.907 [main notice] ebusd 23.1.23.1-26-g30cf1a9 started with auto scan on enhanced device 192.168.178.9:9999
2023-05-31 20:02:17.894 [bus notice] device status: resetting
2023-05-31 20:02:17.894 [bus notice] bus started with own address 31/36
2023-05-31 20:02:17.924 [bus notice] signal acquired
2023-05-31 20:02:18.453 [bus notice] device status: reset, supports info
2023-05-31 20:02:18.458 [bus notice] device status: extra info: firmware 1.1[8419].2[847f], jumpers 0x37

ebusd doesnt show any bus errors, but:

And after a while:

2023-05-31 20:03:21.323 [bus notice] scan 05: ;21;20;40;0020260962;0938;027912;N5
2023-05-31 20:03:21.493 [main error] unable to load scan config 05: no file from vaillant with prefix 05 matches ID "vr921", SW2801, HW5703
2023-05-31 20:03:21.493 [main error] scan config 05: ERR: element not found

a) Is this normal behavior?
b) Can I help with my data/setup to improve/grow the ebusd dataset somehow?

Regards,
