*)    System uses LiFePo4 with other type BMS
    (This can be either a BMS connected via CAN bus or a BMS system in which the 
    batteries are protected from high/low cell voltages by external equipment.)
*)    The battery capacity of the system is 200 Ah.
*)    Sustain voltage 48.00 V.
*)    Cut off voltage for a discharge current of:
    0.005 C= 46.00 V
    0.25 C= 46.00 V
    0.7 C= 46.00 V
    2 C= 46.00 V
*)    Inverting is allowed again when voltage rises 1.20 V above cut-off(0).
*)    Relevant VEConfigure settings:
      -  Battery capacity 200 Ah.

GX device¶

seems to be an : Allwinner sun8i Family

https://www.victronenergy.com/live/ccgx:root_access

ESPhome grid meter
Using the the following extra software on the GX device to enable mqtt devices to connect to the victron GX and be used as a grid meter:
https://github.com/freakent/dbus-mqtt-devices

Using the following ESPHome alternate P1 meter configuration to send P1 data to the GX device AND to home assistant:

after updating the firmware you seem to need to run the setup.sh script again.

esphome p1meter victron version

GX to Home Assistant

To get information from the GX device into home assistant you can use the following HACS addon: https://github.com/sfstar/hass-victron

To get the battery input/output into the energy dashboard you need to split the sensor.victron_system_battery_power into two values with template sensors and add two cummulative entries with the integration platform.

sensor:
    #total battery input energy (cummulate)
  - platform: integration
    source: sensor.battery_power_input
    name: battery_input_energy
    unit_prefix: k
    method: left
    round: 3
    #total battery output energy (cummulate)
  - platform: integration
    source: sensor.battery_power_output
    name: battery_output_energy
    unit_prefix: k
    method: left
    round: 3

GX Venus OS Large

You can update the firmware with a Venus OS Large version. This version includes Node-RED. In the Remote Console, this can be enabled and you can finde node-red on https://venus:1881/

when installing Venus OS Large, you better run

/opt/victronenergy/swupdate-scripts/resize2fs.sh
