Ah, thank you. I never finished the step of adding it in the custom integrations, even though it was working without issues. Now with changing the template as you suggested, it is fixed. Thx

My configuration.yaml contains this:

# Optional/example
  # A template to ease access to the data as "sensor.pv_outputpower" etc.
  - platform: template
    sensors:
      pv_outputpower:
        value_template: "{{ states.sensor.sems_portal.attributes.outputpower }}"
        unit_of_measurement: "W"
        friendly_name: "PV Power output"
      pv_temperature:
        value_template: "{{ states.sensor.sems_portal.attributes.tempperature }}"
        unit_of_measurement: "C"
        friendly_name: "PV Temperature"
      pv_eday:
        value_template: "{{ states.sensor.sems_portal.attributes.eday }}"
        unit_of_measurement: "kWh"
        friendly_name: "PV energy day"
      pv_etotal:
        value_template: "{{ states.sensor.sems_portal.attributes.etotal }}"
        unit_of_measurement: "kWh"
        friendly_name: "PV energy total"
      pv_iday:
        value_template: "{{ states.sensor.sems_portal.attributes.iday }}"
        unit_of_measurement: "€"
        friendly_name: "PV income day"
      pv_itotal:
        value_template: "{{ states.sensor.sems_portal.attributes.itotal }}"
        unit_of_measurement: "€"
        friendly_name: "PV income total"

Hi, the latest plugin version has different sensor ids to support multiple inverters. Please see: https://github.com/TimSoethout/goodwe-sems-home-assistant#extra-optional-templates-to-easy-access-data-as-sensors
