Good morning this is my first post so please excuse if I’m in wrong place, this is for a live CoP reading for a Nibe S 1225 heat pump, but I’m not sure if I have the right sensors, if anyone else has a Nibe s1225 heat pump could confirm they are it would be greatly appreciated.

{% set heat = states('sensor.heating_including_int_add_heat_31578') | float(0) %}
{% set elec = states('sensor.compressor_power_input_31049') | float(0) %}
{% if elec > 0 %}
{{ (heat / elec) | round(2) }}
{% else %}
0
{% endif %}

Many thanks in advance

I believe that is correct yes
FWIW I would recommend using availability on the sensor (i.e. availability: "{{ states('sensor.compressor_power_input_31049') | float(0) > 0 }}") - this will prevent periods the heat pump is off from breaking statistics on the sensor (so you can do things like plot average CoP etc)

Thank you, I’m really new to all this I managed to get copilot to make me a Nibe dashboard which gives me live cop and daily cop as part of the dashboard I’m getting a daily cop of 5.45 and live swings from 3.5 to 9 and I thought this was probably not right

the live swings are probably due to the data updates coming through at different times - e.g. if the power drops, the input power is measured electrically so will update quickly, but the heat out has thermodynamic limits which means it reads high for a little bit so you have big number / small number = CoP too high

#

might be worth doing some filtering on the sensors - e.g. 5-10s rolling average?
