HI,
has anyone had experience with this electricity cooperative and does anyone have an idea how it can be integrated into home automation? There’s also an API interface available.

Thanks for you answers.
Hi, i tinkered a bit and finally got a result in my HA 
put this in your configuration.yaml and you should get a “efriends_pv_meter” sensor.
rest:
- resource: http://<your Cube IP>/v3/MeterDataAPI/getCurrentValue?format=xml
method: GET
scan_interval: 5
headers:
apiKey: "<Your API Key from the App>"
content-type: "application/xml;charset=UTF-8"
sensor:
- name: "eFriends PV Meter"
device_class: energy
value_template: "{{ value_json['energyData']['energyBalance']}}"
this refreshes every 5 seconds on your main screen, you can change that by editing “scan_interval” up or down.
i might tinker a bit more since i want to color it red or green depending on the value shown.
Edit: Also don’t forget to restart HA after pasting this into the config file, otherwise you wont have the sensor available
