Arcus P1 KNX Gateway - showing Entity not defined in setup screen of energy dashboard

Energy
1

Hi All,

I’m trying to integrate my Arcus P1 KNX Gateway (KNX-GW-P1) to my energy dashboard but despite all effort I’m not succeeding. I do something wrong but I have no idea what.

The KNX-GW-P1 is configured to transmit the active energy (Wh) as DataPointType 13.010.

In Home Assistant I have configured the knx sensor as follows:

  - name: "Power van grid"
    state_address: '20/0/13'
    sync_state: True
    type: 'active_energy'
    device_class: 'energy'
    state_class: 'total_increasing'

Looking at the current entity I see the following:
State: 7602038 → this is my total consumed energy from my utility meter in Wh

Attributes:

state_class: total_increasing
source: 1.1.12
unit_of_measurement: Wh
device_class: energy
friendly_name: Power van grid

When I try to add this sensor to the energy dashboard via add consumption from grid, I see the sensor and I can save it but once it is saved I see the message " Entity not defined: Check the integration or your configuration that provides:".

Can someone point me please in the correct direction to get this solved.

Version of Home Assistant I’m using:
Home Assistant 2023.4.0
Supervisor 2023.04.0
Operating System 9.5
Frontend 20230405.0 - latest

Thanks in advance,

Bob.
