update easee charger threshold from ferroamp data

Ferroamp and Easee.txt

This is instructions to dynamic update Easee charger circuit limit with dynamic data from ferroamp without adding additional load to ACE.

Reguired components: 
 Home Assistant with an Easee charger and Ferroamp Energyhub

You need to know or find your circuit id of your Easee charger and that is displayed in various places in the HA / Easee integration.
  
1. Edit configuration.yaml and add these rows below to create a custom sensor for each phase
# Grid Current for Easee charger threshold
sensor: 
  - platform: template
    sensors:
      grid_current_l1:
        value_template: "{{ (state_attr('sensor.ferroamp_grid_current','L1')*-1) | int }}"
        friendly_name: "Grid Current - L1"
        unit_of_measurement: "A"

  - platform: template
    sensors:
      grid_current_l2:
        value_template: "{{ (state_attr('sensor.ferroamp_grid_current','L2')*-1) | int }}"
        friendly_name: "Grid Current - L2"
        unit_of_measurement: "A"

  - platform: template
    sensors:
      grid_current_l3:
        value_template: "{{ (state_attr('sensor.ferroamp_grid_current','L3')*-1) | int }}"
        friendly_name: "Grid Current - L3"
        unit_of_measurement: "A"

2. Restart HA to get the sensors above up and running.

3. Edit automamation.yaml with the following entries as an example, (do it in the GUI)
- id: '1628865016785'
  alias: .Easee - Update circuit threshold
