> Edit: to be clear, I see the negative heat / COP when the circulation pump is running, but the compressor is not

I think, I nailed it, it’s a bit crude -

I created another template that listens to the original COP sensor template,

If the new ‘cop\_true’ template value is in between 0 and 8 that listens to the original COP sensor, log value, otherwise log 0 (no negative or uber efficiency values).

I hope this makes sense. Thoughts on my cowboy approach welcome 😊

```
- name: "cop_true"
  unique_id: "cop_true"
  unit_of_measurement: 'COP'
  state: >
    {% set cop_true = (states('sensor.cop_power') | float ) | int %}
    {% if cop_true >= 0.001 and cop_true <= 9 %}
      {{ states('sensor.cop_power') }}
    {% else %}
      {{ 0 }}
    {% endif %}
  attributes:
      minute_counter: "{{ now().minute }}"

```
