Custom Component DalyBMS for ESPHome

This repository is a collection of my custom components for ESPHome. Just tried on Wemos D1 Mini.

Add sensors (measurements):

    on_failure_status:
    power:
    bms_watchdog:
    cycle:
    cell_voltage_difference:

Add binary_sensors:

    cell_1_balance_active:
    ...
    cell_16_balance_active:

Add sensors (level 1 + 2 setup - just reading):

    cell_level_1_alarm_high_voltage:
    cell_level_2_alarm_high_voltage:
    cell_level_1_alarm_low_voltage:
    cell_level_2_alarm_low_voltage:

    battpack_level_1_alarm_high_voltage:
    battpack_level_2_alarm_high_voltage:
    battpack_level_1_alarm_low_voltage:
    battpack_level_2_alarm_low_voltage:

    cell_level_1_alarm_difference_temperature:
    cell_level_2_alarm_difference_temperature:

    cell_level_1_alarm_difference_voltage:
    cell_level_2_alarm_difference_voltage:

    cell_nominal_capacity:
    cell_nominal_voltage:

How to use / example ESPHome configuration

configuration like original ESPHome-Daly_BMS

you can use more than one daly:

uart:
  - id: uart1
    tx_pin: GPIO17
    rx_pin: GPIO16
    baud_rate: 9600
  - id: uart2
    tx_pin: GPIO22
    rx_pin: GPIO21
    baud_rate: 9600

daly_bms:
  - uart_id: uart1
    id: bms1
    update_interval: 20s
  - uart_id: uart2
    id: bms2
    update_interval: 20s

you can get failure status code: change "template_sens" to your template sensor.

More information can be found here.

  - uart_id: uart1
    id: bms1
    update_interval: 20s
    on_failure_status:
    - lambda: id(fault_code).publish_state(x[7]);
    ...
    ...
sensor:
  - platform: template
    name: Fehlercode
    id: fault_code
