Fox inverter grid power

[JustinWingChungHui]

grid_power is missing from the fox.yaml. I had to create up a template sensor to supply the values.

Is the best way to add comments into the fox template?

Do you have sensor.grid_ct from the FoxESS modbus integration available? It's in kW, positive export, negative import.

Some sensors are inverter-specific, and some are disabled by default (so would need to be enabled). I'm not sure whether this one is in that group.

  #
  # Sensors, more than one can be specified and they will be summed up automatically
  #
  # For two inverters the load today would normally be the master load sensor only (to cover the entire house)
  # If you have three phase and one inverter per phase then you would need three load sensors
  #
  # For pv_today if you have multiple solar inverter inputs then you should include one entry for each inverter
  #
  load_today:
    - sensor.shelly_3em_c8_ch_b_daily_energy
  import_today:
    - sensor.grid_consumption_energy_today
  export_today:
    - sensor.feed_in_energy_today
  pv_today:
    - sensor.solar_energy_today
  grid_power:
    - sensor.grid_ct

Adding in grid_power: - sensor.grid_ct on my system now displays activity from the grid on the power flow chart, whereas previously it was displaying no grid activity.

You are right! Let me amend that PR
