eBUS Adapter Shield C6 and Protherm Medveď Condens 25 KKS

[whitoSB]

Hello everyone, I have problem with Protherm Medveď Condens 25 KKS (Vaillant Group) and eBUS Adapter Shield C6. When I connect the adapter to the boiler, the green diode flashes quickly (communication works). But ebusd in home assistant does not see the boiler during automatic configuration.
log from ebusd:

Is it necessary to have an ebus thermostat connected to the boiler? I don't have an ebus thermostat, only the Adapter Shield C6.

thanks for the responses
sorry for my eng.

Go to the ebusd-configuration repository
Look for the vaillant/ or protherm/ subfolder — many Protherm Condens models share configs with Vaillant ecoTEC or similar.
Download all relevant *.csv files (e.g. bai.csv, bas.csv, hc1.csv, etc.) and put them into /etc/ebusd/

The adapter does not see any device.
Are *.csv files needed for the adapter to detect the device?
