Hello,
after months of perfect communication. I now (nothing changed) lost a lot of information.
Cell voltages is still updated. Other information as SOC for example is not updated.
Using the Bluetooth app on the cell works fine
rebooting Homeassistant and the BMS didn’t help.
Any other idea’s?

Thanks for support

Could you provide an ESPHome log, the BMS model name and the software/hardware version? I've have an idea what's going on.

The issue showed up yesterday 10:20pm
The logs on the phone won’t go back that far.
Software/hardware I habe to check when home

This looks like the log of the ESPHome Dashboard. Could you provide the log of the ESHPhome node? It can be downloaded if you open the ESPHome Node tile at the dashboard. There is a "logs" button at the bottm right corner.

Do you mean this button?

I got to check if I get an download file on the pc. On the cell nothing shows up

No. ;-) Do you use the ESPHome Dashboard? It's an HA Add-On accessible via the main navigation on the left.

I have it running, but not for the jk bms esp.
At that time when installing the esp, I was totally new to HA. A friend of mine flashed the esp…
I have another esp laying around. I could flash it this afternoon using the esp dashboard.

Do you have a copy of the YAML configuration?

[Salve87]

Do you have a copy of the YAML configuration?

Probably not. I was using the file from github

[syssi]

In this case I suggest to start from scratch. Use the BLE configuration example from this project, update the MAC address and flash this configuration using the HA Dashboard to your ESP32. So you have access to the logs in future and you are able to update the device whenever you want.

Ok as suggested, new ESP, new code, new setup: same problem:

This Time I have a log file:
logs_esp32-jk-bms_logs (1).txt

Any Idea whats wrong, why its not working all of a sudden ??
Thanks

[syssi]

Could you tell me your BMS model and software/hardware version?

[Salve87]

sure, sorry forgot

[syssi]

Please change the protocol version from JK02 to JK02_32S and compile & flash your ESP with the updated configuration:

substitutions:
  name: jk-bms
  device_description: "Monitor and control a JK-BMS via bluetooth"
  external_components_source: github://syssi/esphome-jk-bms@main
  mac_address: ...
  protocol_version: JK02_32S

Does this fix the issue?

Reatart helped now it’s running,
Thanks for the support 👍

All measurements are decoded properly again?
