Can I get the browser_id of the current browser in a template?

[JelkeH]

I would like to be able to control the brightness of the current browser by a slider using the light.<<browser_id>>_screen entity. Something like:

type: entities
entities:
  - type: custom:slider-entity-row
    entity: light.{{browser_id}}_screen

Would something like this be possible? I hope the get this working, but currently I'm stuck at being able to retrieve the current browser_id
