For a sensor that is measuring how much watt a device is using I would like to calclulate the energy costs per day in euro’s.
It seems that I am able to do this with this value template sensor:
- platform: template
sensors:
PC enery costs:
friendly_name: “Energy costs per day”
unit_of_measurement: ‘Euro’
value_template: “{{ states(‘sensor.tussenstekkercomputer_power’)|float * 24 / 1000|float * 0.22 | round(2)}}”
I do now however get a lot of decimals (Like 2.122296 Euro). I would like to have just 2 decimals. I thought I would be able to do that using round(2) like this:
- platform: template
sensors:
PC enery costs:
friendly_name: “Energy costs per day”
unit_of_measurement: ‘Euro’
value_template: “{{ states(‘sensor.tussenstekkercomputer_power’)|float * 24 / 1000|float * 0.22 | round(2)}}”
But is still get much more decimals. Any idea where I’m going wrong?
