Feature: Enable state remapping per included group

[scyto]

Is your feature request related to a problem? Please describe.
I am using filters to create a dynamic card.
I have two types of device - one where off = battery dead and one where on = battery dead (this is actually an attribute called heartbeat, which i can't rename, thanks insteon!)

I would like to apply opposite state mappings for these two groups

Describe the solution you'd like
I would like to be able to do something like this:

type: 'custom:battery-state-card'
title: Battery Low
sort_by_level: dsc
filter:
  include:
    - name: entity_id
      value: 'heartbeat'
      state_map:
        - from: 'on'
          to: 0
        - from: 'off'
          to: 100
    - name: entity_id
      value: 'inverse-heartbeat'
      state_map:
        - from: 'on'
          to: 100
        - from: 'off'
          to: 0

I agree it might be useful but unfortunatelly can be quite hard/impossible to implement with the current way how card code works.

I will think about this little bit more hence I will keep this issue open for a bit more but I think I will have to close it later. Sorry

Thanks for considering it, appreciate it.
I guess the easiest way is to just make a second card for these devices :-) especially as it is dynamic card.

I think that we could solve it in the following way. Instead of applying state-map to a group we can apply it conditionally. This way the solution will be more generic - useful in other cases too (e.g. when someone wants the same functionality but don't want to have groups).

The setting can be something like:

state_map:
  - from: "on"
    to: 100
    condition: "{entity_id|contains(inverse)}"

Agree that's useful, now I have to specify all the 'same' entities by hand.
