Question about the VALLHORN PIR

[nipsgur]

Hi Nicolas thanks a lot for sharing this nice library. I got interested in it for the air quality sensors and it works like a charm.

So, now I also got one of the new motion sensors, but I'm struggling a little. (I have to say I don't have any bulb or outlet connected to it) Looks like the motion sensor does not send any events by itself. I also never saw the is_on attribute change to True when I trigger the motion sensor, the only thing that changes is the last_seen attribute.

I have read the other topic about triggering a scene from a remote, but I couldn't figure out if a motion sensor can trigger a scene? So to me it looks like a motion sensor needs to be hard wired to an on/off device?

So my question would be, in the event system, would an on/off device know which other device switched it? In this as a workaround, I could get just one outlet and use it as a dummy to be triggered by all the motion sensors? But maybe a on/off device can only be controlled by one motion sensor?

Would be glad about any suggestions, Torben

I sadly don't know since I don't have one but the Ikea app also only shows action button as trigger for a scene.

I just tested this by switching a light on, first in the app which gave this event:

{
  "id": "53963fa6-8587-4dc3-96fa-3b2fa6a05eb7",
  "time": "2024-05-14T05:50:33.000Z",
  "specversion": "3.150.0",
  "source": "urn:com:ikea:homesmart:iotc:zigbee",
  "type": "deviceStateChanged",
  "data": {
    "id": "d58a09a1-537c-467c-9bcf-1c4be0c2185e_1",
    "type": "light",
    "deviceType": "light",
    "createdAt": "2024-05-02T16:12:36.000Z",
    "isReachable": true,
    "lastSeen": "2024-05-14T07:50:33.000Z",
    "attributes": { "isOn": true },
    "remoteLinks": ["99e6be90-12f0-4708-9c63-b45ed64824d8_1"]
  }
}

and then switching it back off with an Ikea switch, which gave this event:

{
  "id": "57bfff69-fb95-4fe1-9eac-3b56debfa976",
  "time": "2024-05-14T05:51:07.000Z",
  "specversion": "3.150.0",
  "source": "urn:com:ikea:homesmart:iotc:zigbee",
  "type": "deviceStateChanged",
  "data": {
    "id": "d58a09a1-537c-467c-9bcf-1c4be0c2185e_1",
    "type": "light",
    "deviceType": "light",
    "createdAt": "2024-05-02T16:12:36.000Z",
    "isReachable": true,
    "lastSeen": "2024-05-14T07:51:07.000Z",
    "attributes": { "isOn": false },
    "remoteLinks": ["99e6be90-12f0-4708-9c63-b45ed64824d8_1"]
  }
}

I don't see any difference in this data except for the timestamp so I doubt that it is possible to see which real source triggered the action. Although there is a small chance that motion sensors in combination with an outlet behave differently, so if you get a change to verify your hypothesis let me know 😉

I have read the other topic about triggering a scene from a remote, but I couldn't figure out if a motion sensor can trigger a scene?

I found a way! In the app when you go to the system settings and scroll down you will see the feature test center. There you can toggle using sensors as triggers for a scene.

That sounds like a solution, very cool.

I quickly checked, but I only found these three in this "Workshop" test center.

"Matter Bridge integration" "Presets for smart lights" "Pin your favorites"

Maybe I have to wait a little to see the new feature? (I have android app 1.25.1 and dirigera 2.556.0 firmware)

On the other side, if I poll the is_detected Attribute I can see it change to True if a motion is detected and I did not associate any lights or outlets.

ok, the “Start scenes by sensor activity” has not arrived on android jet.

little update, The "Workshop" feature also arrived on android with the last update and now it shows motion events in the listener. I also get an event for the "empty" scene, that I put the motion sensor in, when it was triggered.
