Hi @bayc4d ,
this is rather a question to ebusd software but feel free to keep it open also here.
What do you mean by opentherm firmware?

i cant control with ebusd my boiler. so i want to try opentherm with adapter.

according to my research i need vailant vr33 converter for use with ebus and opentherm protocol.
