Templates

A template sensor to get the delta from the heatpump source input and output:

template:
  - sensor:
    - name: Heat pump source temperature delta
      unique_id: heat_pump_source_temperature_delta
      state: >-
        {% set input = states("sensor.keba_keenergy_12345678_heat_pump_source_input_temperature")|float(0) %}
        {% set output = states("sensor.keba_keenergy_12345678_heat_pump_source_output_temperature")|float(0) %}
        {{ (input - output)|round(2) }}
      icon: mdi:thermometer
      unit_of_measurement: °C
      device_class: temperature
      state_class: measurement

A template sensor to get the delta from the heat pump flow and return flow. This is also posible with the flow and return flow sensor from the heat circuits (if available).

template:
  - sensor:
    - name: Heat pump flow and return temperature delta
      unique_id: heat_pump_flow_and_return_temperature_delta
      state: >-
        {% set flow = states("sensor.keba_keenergy_12345678_heat_pump_flow_temperature")|float(0) %}
        {% set return_flow = states("sensor.keba_keenergy_12345678_heat_pump_return_flow_temperature")|float(0) %}
        {{ (flow - return_flow)|round(2) }}
      icon: mdi:thermometer
      unit_of_measurement: °C
      device_class: temperature
      state_class: measurement

Visualizations

All visualisations required the Lovelace Mini Graph Card.
