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:

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

[[esphome p1meter victron version]]

*GX to Home Assistant*
96
97
To get information from the GX device into home assistant you can use the following HACS addon: https://github.com/sfstar/hass-victron
98
99
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.
