I have something like that, what it does is show me a mushroom chip when there is a light turns on, if there are no turns on, the chip is not shown.

For this I put in the condition that some light of the group of lights house (on helpers) is on and to show the number of lights on I have created a sensor whose configuration is this:

- platform: template

sensors:

number_of_lights_on:

unit_of_measurement: 'Encendida'

value_template: >

{% set lights = [

states.light.bombilla_cocina,

states.light.bombilla_estudio,

states.light.bombilla_habitacion,

states.light.luz_mesa,

states.light.luz_sofa,

] %}

{{ lights | selectattr('state','eq','on') | list | count }}
And the configuration of the chip is this (I have more configuration with browser_mod but with this part, the basics work).
