This requires HomeAssistant custom integrations for Ferroamp / Easee to load balance the max available current to the Easee charger every 30s without the use if Tibber pulse / Equlizer / Watty etc for a more optimized charging experience for your home.

Add these 2 automations above as separate automations
I use the entity "input_number.battery_sts_code" and set it to 1 when I charge the Ferroamp battery as a status flag.
I limit the max current to 45A (16A*3 as my normal max) If the Ferroamp battery is charging with 2000W to allow the house battery to change at the same time during charging of my Eletric car.
And when the Ferroamp battery charging is finished then I release all available current to the Easee charger.
You can find your "device_id" value by accessing http://homeassistant.local:8123/developer-tools/service
Type in the Service "Easee EV Charger: Set charging cost"
and add your charger using the GUI and then look into the created yaml code to see your device_id for your Easee charger.

The second automations set the Easee charger to a charge level that is safe, in my case 10A as a precaution if the HA isn't online the next time the charger starts to minimize the risk of a burned burn fuse.

My Ferroamp system has ACE set to 15A to balance the phases the last current even to the phases because my Kia EV6 don't seems to like different currents on the phases when charging.

As always. Use this code at your own risk and don't blame me if things go bad :)

Thanks alot, using it with Ferroamp and Easee. I used the power for one of my ESO:s to control if the battery is charging, set it to be above 200 W of charging before lowering the charge amp to the Easee box.
Works good so far!
