Make the number of decimal digits contextual

[Ndrinta]

Hi, first of all, great job @ulic75!

Second of all, I've noticed that the setting for kw_decimal is used also when the figure is below the watt_threshold and simple Watts are displayed.
I'd be great if we could have a similar parameter when in the 'below-threshold' region, too. Maybe, simply w_decimal.

A further upgrade would be to be able to specify the unit of measure (I'd kinda like to have at least the option to use it to display energy (kWh/Wh) instead of instantaneous power). I know this would be a 'different use' for this card, but flexibility is always a plus IMHO).

Oh, correction. Actually no, kw_decimal is not used in the 'below-threshold' region.

  private displayValue = (value: number) =>
    value >= this._config!.watt_threshold
      ? `${round(value / 1000, this._config!.kw_decimals)} kW`
      : `${round(value, 1)} W`;

It always rounds it up to the first decimal. I haven't noticed it because I also have kw_decimal set equal to 1.
Anyways, same issue, not customizable so no good.
Looks like a super easy fix, I'll make a pull request tomorrow; but only if there isn't friction by anyone, of course. :)

Comments are editable 😄 My entities only supply kW up to 3 decimals, so I guess I assumed whole watts would be small enough. Your system actually provides measurements smaller than a single watt?

As for the second part of your original issue, I don't think that is likely to happen as that is what the official Energy Distribution card does.

I don't like to see edited on my comments. Just regular OCD.

I have enough resolution to monitor decimals of Watts, I don't wanna see them on the card, though.

Yep, but not as a card in the regular Lovelace (anyways, secondary).

https://www.home-assistant.io/dashboards/energy/ They aren't available via the card picker, but you can use them on any dashboard you'd like. I've made my own custom dashboard that includes many of these, plus power-flow-card. Granted they have almost zero customizability.

I completely missed this, the more you know...

I'm not sure why you closed your PRs. Anyhow, I've included the option. Thanks again for your contribution.
