Protherm gepard 23 is not responding.

[vicitacal]

Please, help me with communicating via ebus with the protherm gepard 23 boiler.
My setup is esp8266 with ebusd-esp firmware and ebus daemon latest version in docker 24.0.7.
Ebus adapter is work properly.

Voltage level converter is self-made, but it tested many times and i shure that it is work good.
But in ebus daemon logs i see only this:

As far as I understand, --scanconfig cannot determine the config because it does not receive a response to the Identification (07h 04h) request.
I've tried everything I know.
