Hi! if you need some help I have 3 packs seplos boxes with bluetooth and I can make tests. I saw that on display board with bluetooth there is also space for an esp12f board. If you want to test this I can add a board there, I can also give you access to my systems if you want to test directly yourself. Have a good day!

Hy Syssi,

have been trying to get the bluetooth to work for the last few days, but unfortunately can't get anything out ...

any idea what I can do to make it pull the data?
Here is the debug log from the current attempt:

@manznOnly thanks for poking around. This feature isn't ready yet but your logs look promising already. Just the requests aren't implemented yet so we are sending garbage at the moment:

I understand, if you need someone to test - let me know - i have 6 Packs for testing :D

@syssi Here are the bluetooth specs for 10E. You could put them into the doc section.

any update on this if I may ask? Does BT work with the Seplos BMS and ESPHome?

Hi @syssi , I will ask :) . At what stage is the work with BLE? I have always used RS485 connection, however, a bank of 3 storages was created and BLE would already be useful to monitor all of them :(

The implementation has pretty low priority because the demand is very small. Do you have a working setup already and would you offer some testing?

Thanks for the reply. Yes I have everything and can offer tests :). I even already installed the code esp32-ble-example.yaml.

Hm, I tried the example code and this is what I see in the log:

[20:06:28][W][seplos_bms_ble:202]: Command queue (2 of 6) was not completely processed. Please increase the update_interval if you see this warning frequently
[20:06:28][D][seplos_bms_ble:586]: Send command (handle 0x14): 55.04.83.AA

The update interval warning shows up frequently then. I have set it to 30s already...

For those of you interested - there is now a Home Assistant integration that allows reading out individual packs and cell voltages over Bluetooth: https://github.com/patman15/BMS_BLE-HA
