Remaining Capacity in kWh additional to Ah

[dominikfe]

Would be a nice to have feature and should not be too much effort?

[syssi]

Could you try this proposal: #80

If it's working for you I would like to add it to the example configurations.

Oh, you are asking about the state of charge in kWh. Let me think about it.

To calculate the remaining kWh we need the nominal voltage of the battery. You should use a template sensor:

sensor:
  - platform: jk_bms_ble
    jk_bms_ble_id: bms0
    capacity_remaining:
      name: "${name} capacity remaining"
      id: capacity_remaining_sensor
      
  - platform: template
    name: "${name} energy remaining"
    unit_of_measurement: "kWh"
    device_class: "energy"
    lambda: |-
       auto val = id(capacity_remaining_sensor).state * 48.0f;
       if (isnan(val))
          return {};
       return val;
    update_interval: 10s
