Using Calibrate for Media Players that express volumes in decimals

[TheManoeuvre]

I'm trying to add my homepods with powercalc so I can flesh out my energy reporting. I want a group sensor for all Homepods and include the individual energy reporting from each Homepod volume when playing (using this site as my source for power usage: link)

For the calibrate section, if I insert as below the YAML fails when checking the config with the error reading " valid config for [sensor.powercalc]: does not match regular expression ^[0-9]+ -> ([0-9]*[.])?[0-9]+$ @ data['entities'][0]['linear']['calibrate'][0]. Got '0.3 -> 0.81" and repeating for each line of 'calibrate'.

if I'm reading this correctly the calibrate section is expecting an integer before -> not a decimal, however Homepods report volume in decimals when using the Apple TV integration. If I try changing these to integers (30 -> 0.18 etc) I start getting funny values out of it.

How I'm supposed to correctly configure the calibrate section for this?

- platform: powercalc
  create_group: HomePods
  entities:
    - entity_id: media_player.office_homepod_mini
      standby_power: 0.27
      linear:
        min_power: 0.27
        max_power: 9.19
        calibrate:
          - 0.3 -> 0.81
          - 0.5 -> 1.17
          - 0.7 -> 2.25
          - 0.8 -> 4.68
          - 1.0 -> 9.19

Missed notification of this post. I saw you also asked this question on reddit.
I did answer there as well today so copying my answer here for others:

=======================

For media_player entities powercalc will asume volume attribute and converts this to scale 0-100. When using the calibrate option you should omit min_power and max_power.

Hope this helps. When it still does not please create an issue on github, than we can have a look what causes this and how to resolve?

Also would be a good idea to submit this power profile in the powercalc library so other users using homepod will also get a power sensor setup out of the box (using discovery).
