Read sensor values from http xml address

Hello @ all,
i have a problem with read sensor values from http link (xml).
No values will import to HA.
Would anyone have a tip for me?
The sensors are displayed under entities but with this text:

This entity is no longer being provided by the rest integration. If the entity is no longer in use, delete it in settings.

Thats my setup:

My configuration.yaml config:

  - resource: "http://IP/System/Properties/Process/Bus1/"
    scan_interval: 60
      - name: A_mW
        value_template: "{{ value_json.Bus1.Device_2.Variable_14 }}"
        unique_id: A_mW
        unit_of_measurement: "mW"
      - name: B_mW
        value_template: "{{ value_json.Bus1.Device_2.Variable_4 }}"
        unique_id: B_mW
        unit_of_measurement: "mW"
      - name: C_mW
        value_template: "{{ value_json.Bus1.Device_2.Variable_5 }}"
        unique_id: C_mW
        unit_of_measurement: "mW"
      - name: D_mW
        value_template: "{{ value_json.Bus1.Device_2.Variable_6 }}"
        unique_id: D_mW
        unit_of_measurement: "mW"

XML from link:

<DeviceState _="1"/>
<ChangeToggle _="0"/>
<Variable_4 _="143300"/>
<Variable_5 _="36200"/>
<Variable_6 _="223000"/>
<Variable_14 _="402600"/>
<Active _="1"/>
<FreeMem _="105344"/>
