Please describe the enhancement you would like to have.

In the latest BMS Firmware (since V15.35 - now i am running V15.38) there are some new Parameters:

-Charge Status (Bulk-Absorbtion-Float)
-Charge Status Time (in Sec, indicates the time in Absorbtion mode)
-And the Status of the two dry Contacts (not interesting for me personal, but listed for compleatness)

Here you can see them at the bottom of the pic

Here a debug log from newest 15.38 where i reactivated both BMS at the beginning to have a full connecting cycle in the log
home-assistant_bms_ble_2025-01-11T09-31-35.657Z.log

I assume you need more information for implementing, but this is all i have at the moment, maybe you can read something out of that.

Would be nice to log the charge status parameters for debug an fine tune the absorption timer settings

Charge Status (Bulk-Absorbtion-Float)

Makes sense to me. What about adding it as an attribute to the battery_charging sensor? Would that be fine with you?

The others sound too geeky and are very unique to the JK.

[downset]

Fine for me as Attribute

Would like to see the Timer too but I understand the uniqueness argument :)

Ok, I managed to fake a BMS to the app, but my app does not seem to show these parameters. Where did you get it from?

[downset]

I am using IOS, there it was updated on the 5.1.25 to V4.30 direkt from the App store

Hmm, I fear, I cannot do much until the Android app is updated. Unless you are able to provide me 3 debug logs each for one of the states Bulk-Absorbtion-Float. Then I might be able to guess it from the binary data.

Okay I will come back as soon as I have more infos there is some Sun in the weather forecast maybe I can get som logs soon.
Also Andy from the offgridgarage stated in the last video he has the Beta of the new app maybe he post it on his google drive then i inform you also.

Seems Apple is faster this time than the Android release :D

I just found a source for the 4.3 android beta APK

Thanks @downset will have a look next week!

Status update: I'm having troubles getting my JK emulation working, thus I cannot decode the new status flag. If your @downset or someone else has the patience to generate separated debug logs for the three states Bulk-Absorbtion-Float it would help / speed-up the implementation quite a lot.
Will continue fixing my emulation ...
