Virtual Device Calculation from W to kWh

[Jeypee]

Hello,

i wanted to impliment a counter for my fridge, microwave and so on. I cant connect a smart-plugin behind my fridge/microwave (to less space).

I created a number helper “input_number.sonstige_watt” with the value “20” (Power: 20 W).
Now i need a counter to calculate the “kWh”. But no plan how i do that.
I found someone who has a real counter for Power, but that dont work for me. Link

I tried this:

- platform: integration
   source: input_number.sonstige_watt
   name: sonstige_verbrauch
   unit_prefix: k
   unit_time: h
   round: 2
   # method: left

But only get this:

Need some help…

You should be able to do what you want with this:

Powercalc - Virtual power sensors

In the last few weeks I have been working on a custom component to get virtual power sensors for your lights or other devices. It is stable enough right now to share it on this forum and make dedicated topic for it. The component provides multiple strategies to calculate estimated power consumption. One of the most interesting is the LUT method (using lookup tables). Some community members and me have taken measurements for all kind of different brightness/hue/saturation settings and their resp…

I think the problem is that “input_number.sonstige_watt” is an string and not an int. How can set it in line “source:” to int ?
