add Message, CONFIGURATION, VERSION

[ananyevgv]

Good afternoon, some boilers require messaging, otherwise they cannot be controlled:

OpenThermMessageType::READ_DATA, OpenThermMessageID::BOILER_CONFIGURATION, 0xFFFF);
uint8_t SlaveMemberIDcode = respons3 >> 0 & 0xFF;
OpenThermMessageType::WRITE_DATA, OpenThermMessageID::DEVICE_CONFIGURATION, SlaveMemberIDcode);

OpenThermMessageType::READ_DATA, OpenThermMessageID::BOILER_VERSION, 0);
OpenThermMessageType::WRITE_DATA, OpenThermMessageID::DEVICE_VERSION, 0x013F);

How do you mean? Are these specific messages that must be written over and over again? Or just once at startup (of the boiler I assume). How can it be detected that the messages need to be written?

[ananyevgv]

Before transmitting control and status information, it is recommended to exchange messages about the acceptable configuration of the slave. READ HB CONFIGURATION > WRITE LB CONFIGURATION. VERSION WRITE 0x013F

I see, interesting. However the documents state that a MemberID code of 0 indicates a customer non-specific device, which I guess this software is. Not sure whether it's a good idea to mimic the boiler's MemberID here. Any reason why you'd to that? I'd rather just write 0.

Additionally, where do you get the 0x013F value from? Is that a specific vendor?

Reading the slave configuration already happens, to I guess that's already fine.

In all the examples that I found on the Internet, such a code, unfortunately, I cannot say what it means. You can try with 0 and saw this example "master_id: 4 # default 0, baxi 4"

Maybe it makes sense to make it configurable 🤔

Yes

It may come in handy

I'm sorry, I accidentally created pach, I can't delete it.
