How can I change this script to display only two decimal places? the Round option does not work, it displays the result 0.9999999191919191 sensors: encja_wynikowa_cop: friendly_name_template: "COP" unique_id: COP availability_template: >- {%- if not i…

It is rounding your second number before the division. Need some paranthesis in there. {{ ((states('sensor.encja_wynikowa_moc_wymmienika') | float) / states('sensor.encja_wynikowa_4')) | round(2) }}

I’ve read it and there’s not much in it for my script. Please tell me what I’m doing wrong

The point arganto is making is that the syntax should really be correct so that if something does happen, you won’t get an error. In this case: states('sensor.encja_wynikowa_moc_wymmienika') | float(0) The syntax for float is float(default). So, if there is an invalid numeric state (such as unav…

this is a script measuring COP for a Heat Pump converted from an air conditioner. And it works properly. But the annoying thing is that when the Heat Pump is not working, it keeps counting and comes up with values like 0.988467823485477 kW and 160 kW, which may confirm the correctness of the calcula…

Result two decimal places
