Use ISY scenes where your scenes share common lights

One of the hassles of ISY scenes is that you often use multiple lights in multiple scenes. For instance, I have two scenes in the ISY called “Family Room Main” and “Movie”. They each control a light with the HA entity_id called light.two2frb4_fr_spotlight, however the Movie scene sets this value at 12% and the other 55%. So by creating multiple binary sensors with the exact name of the corresponding scene switch (scenes come in from the ISY as a switch) you can set the logic to determine when each scene is on. Below I used logic if the actual brightness is within 5 points of the target value. You could make these more complex if you want.

The glance card below displays the sensors, and when tapped call script sensor_source_toggle which passes in the sensor and converts that to a switch (which is why the names need to match) and will toggle the switch based upon the sensor value.

binary sensors

    family_room_main:
      value_template: >-
        {% set pct = ((states.light.two2frb4_fr_spotlight.attributes.brightness | float / 255) | abs )%}
        {% set ret = (0.5 <= pct) and (pct <= 0.6) %}
        {{ ret }}

    movie:
      value_template: >-
        {% set pct = ((states.light.two2frb4_fr_spotlight.attributes.brightness | float / 255) | abs )%}
        {% set ret = (0.07 <= pct) and (pct <= 0.17) %}
        {{ ret }}

script

sensor_source_toggle:
  sequence:
    - service_template: >
        {% if is_state(entity_id, 'on') %}
          switch.turn_off
        {% else %}
          switch.turn_on
        {% endif %}
      data_template:   
        entity_id: >-
          {% set entity = (entity_id | replace("binary_sensor.","switch.")) %}
          {{entity}}
