Can you get me a debug log to see what the integration says? Thanks!

[downset]

Here it is

I don't know why your BMS likes to send additional "AT\r\n" messages while others don't. Seems to be some strange setting. Can you try the branch, which filters them?

[downset]

and there it is back
quck fix :)

maybe it is cause of the newest firmware v35?
This has also new values eg if it is in float or bulk charge mode and some more, but until now even the original app can`t show them

Thanks for your quick support

[downset]

i have to reopen this again.
After some time with the fix, the BMS shows false values
Some are 0 some are extrem high e.g. Voltage of 4.294.967,3 V
Reloading the pack in the integration fixes it for some hours
Here is a lock wile it is in this State

Excellent catch, thanks for the logs! Can you try this branch? By the way, this was not a newly introduced issue, but already existent in previous versions.

[downset]

interesting, have had sometimes reconnect problems in the past, so that the BMS was offline for some hours, but thought, it is caused of the bad wifi in the Inverter and Battery Room.
But have never had this strange numbers bevor.

The Branch is installed, and the BMS both show up,
Will come back here after abut 24h to confirm if it keeps going

happy Christmas, and don't code to much in these days :)

[patman15]

BMS was offline for some hours

Should be fixed now. Reason was an unhandled exception during the initialization. Quite unlikely, but can happen ...

happy Christmas, and don't code to much in these days :)

Merry Christmas too you! Good hint, on the other hand the best time for long uninterrupted sessions. 😉

Sorry if this is a no go, but i want to share my problem, and not open a new issue. I have a perfect balanced 8S battery with winston cells and a xiaoxiang BMS. After installing the plugin, my cell nr 5 started to deplete very fast, and unbalanced the battery. My first idea was som bad connection to the sensor wires. After re balancing the battery, and turned off the BMS BLE the battery stays balanced.

Sorry if this is a no go, but i want to share my problem, and not open a new issue.

Thanks for sharing. To me this looks like a defective cell, not related to the integration at all. If you want me to look deeper, please open a new issue and provide debug logs, since this issue is not at all related to the topic of this thread, neither the BMS type nor the problem.

[downset]

I think you can close and merge :)
not fully 24h later, but rock stable not even one point with missing data
