Support Creabest BMS / CBT Power

[snipah]

Hi Fabian,
it would be great if you could support Creabest-BMS too. Willing to support BMS-Captures of course. Just let me know what I need to do.

Ich glaube rausgefunden zu haben, dass Creabest die Produkte der CBT Power umlabelt und somit auch deren BMS verwendet. Dazu habe ich folgendes gefunden: https://www.mikrocontroller.net/topic/513514
Kommunikationsprotokoll_der_VB-Serie-DE.pdf

Dass ganze ist zwar für serielle Kommunikation, die mein Akku mangels Schnittstelle nicht beherrscht, vielleicht hilft es aber trotzdem.

ich folge mal gespannt.... :-)

Hello snipah,

konntest Du das Problem lösen?
Es ist mir endlich gelungen, Daten zu empfangen, kann aber damitn wenig anfangen, da sie nicht constant sind, sondern continuirlich oszillieren.
Danke und Grüße
Alex

Hi Alex! Unfortunately not. Did you receive the data via Bluetooth? Are they of any help for us? I'm not really techy enough to support, but would really love having support for this BMS ;)

[Alex-DeIt]

Hi snipah,

yes, I receive them via Bluetooth. This is what I am getting through Batmon:

The problem which I have is that the values are not constant but oscillating. Hier is for example the graph related to the tension:

Hi, I would also be interested getting data from Creabest batteries.
How did you manage to receive data?

[snipah]

Wasn't me, it was Alex-DeIt. But if I remember correctly, he simply used the dummy parameter, which simply outputs fake/dummy-data

[Gruni22]

@snipah Ah, Now I‘ve read the other issue.
So I guess, you also didn‘t have success, so far.
I am also trying to get data out of a CREABEST Battery.

Hi @snipah
Have you tried the integration from Patrick? https://github.com/patman15/BMS_BLE-HA
You can add further battery types there on request.

[Gruni22]

Looks promising, but only reports now Supported Type.
I tried to do some reverse Engineering the Android App and found some useful Information.
I have to continue with further investigation.

Thanks... already filed a request... hopefully we can get this sorted out

Would be great if you could also report it into my request.. patman15/BMS_BLE-HA#59

I prepared bunch of data of a working (Java) setup.
But I do not know, how to push a branch.
I uploaded my work here.

@fl4p In case you did not notice: Gruni22 supplied all relevant information to support a new battery brand.
