Hello Community, Victron Staff
I’m looking for the VE.Direct register description/documentation of the VE.Direct output of the blue smart charger 12 | 30. Can any one help me?

Here the list of registers that I found:

I am putting here a list with what I’ve got.

Hello Alex,
Thank you very much. I’will see what I can :slight_smile:
Here you can see your Excel Sheet in fancy style:

Hi Alex,
finally you can find an application on GitHub

Thanks for sharing!

Not understanding right…
You have IDs that are not present on that (my) list with over 1200 IDs?
Or the other way around?

9

Python lingo… :-)))

Well, I’ve said that not all devices respond to all IDs…
Also it may be an “official” list, as the yellow ones are IDs that Multi RS are responding to, but were not initially included on the list.
So may be - at least from the time of the initial list - other “undocumented” ones.
You can write a small program (or script :-)) ) to scroll the entire base (from 0x0010 to 0xFFFF) and see which ones respond in your case.

11

“void” your device??? what do you mean?
If a register is not known, the appropriate error is thrown. Usually an 0x8000 error.

One thing is reverse engineer a firmware and another is to interrogate the device, with the appropriate, publicly supplied and documented protocol, to find out the IDs…

13

I’ve been trying to make sense of the Victron bluetooth protocol to pull trend data off my smartshunt. This spreadsheet of registers has been very helpful. How did you get these? I’m trying to identify a few more IDs, including EC5B which appears to be trend data.

14

You can find the updated list on the second message of this thread.

15

Cheers, yeah I saw that. I was just wondering how you generated it. In the process of reverse engineering the bluetooth protocol, I’ve found the shunt is reporting a bunch of IDs not on the list. It would be great if I could get there names somehow.

16

Take a look at the list now. I’ve update it this morning after your message. And your EC5B example is there now…

17

Champion! That should help.
