Automatic grouping by device

[sikraemer]

Is your feature request related to a problem? Please describe.
Hey,

I have some devices that provide both a percentage value as well as a battery low state.
(e.g. using the Battery Notes integration).
For other devices I only have the battery low state.

In cases where both values are available the current solution does not allow to exclude one of them, which makes the same device appear twice.

Describe the solution you'd like
It would be nice to automatically group entities by the device they are part of.

Additional context

type: custom:battery-state-card
title: Battery States
secondary_info: "{attributes.battery_type_and_quantity}"
round: 0
filter:
  include:
    - name: entity_id
      value: "*_battery_plus"
    - name: entity_id
      value: "*_battery_plus_low"
bulk_rename:
  - from: Battery+
  - from: Battery low
state_map:
  - from: "off"
    to: 100%
  - from: "on"
    to: 10%
collapse: 5
sort:
  - state
  - name

One can work around this by setting the binary sensor entity to "hidden".

Unfortunately this hides it everywhere and not only as part of the card
