Dynamic individual loads show / hide

[michaeljaddy]

Hi folks,

I'd like my individual load (my EV) to appear dynamically when plugged in and disappear when unplugged (even if not charging).

I am using the following code:

type: custom:power-flow-card-plus
entities:
  battery:
    entity:
      consumption: sensor.lux_battery_discharge_live
      production: sensor.lux_battery_charge_live
    state_of_charge: sensor.lux_battery
  grid:
    entity:
      consumption: sensor.lux_power_from_grid_live
      production: sensor.lux_power_to_grid_live
  solar:
    entity: sensor.lux_solar_output_live
    display_zero_state: true
    display_zero_tolerance: 20
  home:
    entity: sensor.lux_new_home_consumption_live
    subtract_individual: true
  individual1:
    entity: sensor.myenergi_zappi_20462329_power_ct_internal_load
    icon: mdi:car
    name: Polestar
    display_zero: {{ states('sensor.myenergi_zappi_20462329_plug_status') == 'EV Connected' }}
    calculate_flow_rate: true
    color_icon: false
    inverted_animation: false
    display_zero_state: true
    secondary_info:
      entity: select.myenergi_zappi_20462329_charge_mode
      icon: ''
    show_direction: false
    color:
      - 95
      - 167
      - 119
  fossil_fuel_percentage:
    display_zero: false
    display_zero_state: false
clickable_entities: true
display_zero_lines:
  mode: show
  transparency: 50
  grey_color:
    - 189
    - 189
    - 189
use_new_flow_rate_model: true
w_decimals: 0
kw_decimals: 1
min_flow_rate: 0.75
max_flow_rate: 6
max_expected_power: 2000
min_expected_power: 0.01
watt_threshold: 1000
transparency_zero_lines: 0

Notably this line:
display_zero: {{ states('sensor.myenergi_zappi_20462329_plug_status') == 'EV Connected' }}

This does output the value "true":

Does anyone know how to make this work?

Many thanks

Mike
