Hi, how can I change the yaml code to connect 3 or more BMS JBDs using BLE? And how can I add a current sensor to the code? The current yaml only shows charging and discharging. I've tried various methods and I keep getting errors...

[syssi]

sensor:
  - platform: jbd_bms_ble
    jbd_bms_ble_id: bms0
    power:
      name: "${bms0} power"
    state_of_charge:
      name: "${bms0} state of charge"
    total_voltage:
      name: "${bms0} total voltage"
    average_cell_voltage:
      name: "${bms0} average cell voltage"
    delta_cell_voltage:
      name: "${bms0} delta cell voltage"
    # ...
    current:
      name: "${bms0} current"


  - platform: jbd_bms_ble
    jbd_bms_ble_id: bms1
    power:
      name: "${bms1} power"
    state_of_charge:
      name: "${bms1} state of charge"
    total_voltage:
      name: "${bms1} total voltage"
    average_cell_voltage:
      name: "${bms1} average cell voltage"
    delta_cell_voltage:
      name: "${bms1} delta cell voltage"
    # ...
    current:
      name: "${bms1} current"

Does this example help already?

That's what I did before I wrote here, unfortunately there is a mistake

Could you provide your YAML configuration? The copy platform isn't used at the example configuration YAML from this project.

[syssi]

The YAML compiles fine. Please try a clean build (esphome clean yourconfig.yaml). If you use the Home Assistant Add-on there should be a "clean build" button.

[anuluj85]

works!!! works!!! Thank you for your help
I tried to add a third BMS but unfortunately it doesn't work anymore, I am grateful and happy again thank you

[syssi]

I've added a third device to the YAML. Please give it a try:

The same applies to adding the third BMS in Mac Addresses and the eyelid of the code about BMS2 does not want to pass
