ferroamp unsupported CloudAPI.txt

This gist is for ferroamp energy system with integration to Home Assistant to add the option to control "Export Threshold" dynamically
the API is not supported by ferroamp so use it at your own risk!! and it's written for PoC purposes for #Geeks :)
By Daniel Olsson 

This scripts below needs to be updated with email / password and facility ID to work.

1. Create a shell script on the Home Assistant server at /config/shell/ferroamp_cloudapi.sh
3. Modify configuration.yaml to add command_line module / input_number / shell_command.
4. Add automation to map any change to the input_number to trigger a change in the portal as the examle in automations.yaml
5. Reboot Home Assistant and give it a try by changing export_threshold manually of with an automation.
