Use Philips Hue Scenes as Triggers?

Third party integrations Node-RED
1

Is it possible to use a Philips Hue Scene as a trigger? Most of the lights I have in my home are Philips Hue, and my family prefer to use the Hue app or Hue buttons to trigger scenes. I would like to dim additional lights (Caseta, Wemo, Z-Wave). So in short, any time a Hue Scene is called, I would like to catch that in Node-RED and adjust additional lights or appliances.

I have tried using HueMagic nodes, but have not been able to figure out how to use scenes as triggers. Any help would be much appreciated J

I realize this is an old thread, but I’m looking to do the exact same thing as the OP. Any way to pull a Hue scene into Node Red?

Still an old thread. I was just digging into trying to detect this today and found this thread.

It seems there are 2 events that get triggered when scenes are changed from within Home Assistant.

State Change Event:

{
  "event_type": "state_changed",
  "entity_id": "scene.living_room_nightlight",
  "event": {
    "entity_id": "scene.living_room_nightlight",
    "old_state": {
      "entity_id": "scene.living_room_nightlight",
      "state": "2023-07-04T21:06:43.832504+00:00",
      "attributes": {
        "group_name": "Living room",
        "group_type": "room",
        "name": "Nightlight",
        "speed": 0.6031746031746031,
        "brightness": 9.84,
        "is_dynamic": false,
        "friendly_name": "Living room Nightlight"
      },
      "last_changed": "2023-07-04T21:06:43.832701+00:00",
      "last_updated": "2023-07-04T21:06:43.832701+00:00",
      "context": {
        "id": "01H4HBN8FQ1VANYBPVZFXXKRMK",
        "parent_id": null,
        "user_id": "502e0b8392d74ddb9da39e07bc227c96"
      }
    },
    "new_state": {
      "entity_id": "scene.living_room_nightlight",
      "state": "2023-07-04T22:05:27.942749+00:00",
      "attributes": {
        "group_name": "Living room",
        "group_type": "room",
        "name": "Nightlight",
        "speed": 0.6031746031746031,
        "brightness": 9.84,
        "is_dynamic": false,
        "friendly_name": "Living room Nightlight"
      },
      "last_changed": "2023-07-04T22:05:27.943032+00:00",
      "last_updated": "2023-07-04T22:05:27.943032+00:00",
      "context": {
        "id": "01H4HF0T03T7HVFT377787R0MS",
        "parent_id": null,
        "user_id": "502e0b8392d74ddb9da39e07bc227c96"
      }
    }
  },
  "origin": "LOCAL",
  "time_fired": "2023-07-04T22:05:27.943032+00:00",
  "context": {
    "id": "01H4HF0T03T7HVFT377787R0MS",
    "parent_id": null,
    "user_id": "502e0b8392d74ddb9da39e07bc227c96"
  }
}

Call Service Event:

{
  "event_type": "call_service",
  "event": {
    "domain": "scene",
    "service": "turn_on",
    "service_data": {
      "entity_id": [
        "scene.living_room_nightlight"
      ]
    }
  },
  "origin": "LOCAL",
  "time_fired": "2023-07-04T22:05:27.940196+00:00",
  "context": {
    "id": "01H4HF0T03T7HVFT377787R0MS",
    "parent_id": null,
    "user_id": "502e0b8392d74ddb9da39e07bc227c96"
  }
}

However, no event is fired when the scene is triggered via the Hue app. There is one case where the hue app does trigger a scene event, however. That’s when setting the “Natural Light” theme. Not sure why only that one triggers the HA event, and no others do, though.

If the fam can be trained to use the Home Assistant app to set scenes instead of the hue, you could definitely react to that. This is as close as I could get.
