Configurable default precision for entities

[Acrivec]

Describe your core improvement

Please add a way to globally set precision for certain metrics, like Voltage, Amperage, Wattage.
Right now it defaults to god awful precisions and I have to manually change every. single. device. I. have.

I already have

homeassistant:
  customize_glob:
    "sensor.*voltage*":
      suggested_display_precision: 1

    "sensor.*power*":
      suggested_display_precision: 0

In my config.yaml, but it doesn't seem to work.

Current limitations

Currently, with your last year decision, all new entities have default precisions which we can't globally change. BAD decision.

Technical benefits

Some people need precision in their graphs. For some stuff it's crucial, like battery levels. You can't round up to 1V!
It should NEVER be defaulted to such high rounding values!

Additional context

No response

[Petro31]

The integrations set the default precision based on what the sensor can provide. There never was a global precision, global precision change, or any "decisions" to change global precisions.

BAD decision.

Please keep this civil as well.
