Listening to Hue Events

General
1

Hi, been using node red for some years now but I've become stuck.
Basically I had a flow using Hue Magic hue light node to turn on some lights in the garden if motion detected (I use the function node to set the payload with the brightness and colour) and then automatically turn off after 5 minutes of no motion. Here is the flow in question:

But due to some issues I've decided to go down the Hue API V2 route and managed to get a flow working to turn on a light. But I still need to turn the lights off automatically after a certain time. So I was thinking of using philipshue-events node by yadomi.

I thought there would be a simple way of listening to the events and match the light guid with the on state as per this example:

{
  "creationtime": "2021-10-18T17:04:55Z",
  "data": [
    {
      "id": "e706416a-8c92-46ef-8589-3453f3235b13",
      "on": { "on": true },
      "owner": {
        "rid": "3f4ac4e9-d67a-4dbd-8a16-5ea7e373f281",
        "rtype": "device"
      },
      "type": "light"
    }
  ],
  "id": "9de116fc-5fd2-4b74-8414-0f30cb2cbe04",
  "type": "update"
}

My thought process would be if the id = the lights guid and the on state = true I could then start the timer using the stoptimer node and then call the Hue APi again to turn off the light.

I have 3 lights so I would need 3 timers (maybe 2), I wrote a small bit of Js in the function node which is included in this flow:

After some trial an error I have come up with this function which interrogates the event from the Hue Hub and returns the ID, I might just change the function to evaluate msg.payload.data[0].on.on and return the ID into the Topic if True, The Switch node will then take care of the rest .

const manCaveLight = 'ID of light';
const patioLight = ''ID of light';
const shedLed = ''ID of light;
const gardenLed = 'ID of light';


if( msg.payload.data[0].id === manCaveLight
   && msg.payload.data[0].on.on === true ){
     msg.topic = manCaveLight
}
else if (msg.payload.data[0].id === patioLight
   && msg.payload.data[0].on.on === true){
     msg.topic = patioLight
}
else if (msg.payload.data[0].id === shedLed
   && msg.payload.data[0].on.on === true){
     msg.topic = shedLed
       
   }
else if (msg.payload.data[0].id === gardenLed
   && msg.payload.data[0].on.on === true){
     msg.topic = gardenLed
       
   }
   
   
return msg;

Here is my flow:

Hi. Here is an example of same thing using a lookup table. Hope it gives you some ideas

[{"id":"7b563836.da0618","type":"inject","z":"9a86d59e88442f2c","name":"garden","props":[{"p":"msg.payload.data[0].on.on","v":"true","vt":"bool"},{"p":"payload.data[0].id","v":"123456789011","vt":"num"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":170,"y":200,"wires":[["11373201.a198e6"]]},{"id":"11373201.a198e6","type":"function","z":"9a86d59e88442f2c","name":"","func":"const lookup = {\n    \"ID of light1\": \"manCaveLight\",\n    \"ID of light2\": \"patioLight\",\n    \"ID of light3\": \"shedLed\",\n    \"123456789011\": \"gardenLed\"\n};\n\nif(msg.payload.data[0].on.on === true){\n    msg.topic = lookup[msg.payload.data[0].id];\n}else{\n    msg = null;\n}\n\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":320,"y":200,"wires":[["75bd5896.d0bad"]]},{"id":"3a75696b.88a646","type":"inject","z":"9a86d59e88442f2c","name":"cave","props":[{"p":"msg.payload.data[0].on.on","v":"true","vt":"bool"},{"p":"payload.data[0].id","v":"ID of light1","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":150,"y":240,"wires":[["11373201.a198e6"]]},{"id":"75bd5896.d0bad","type":"debug","z":"9a86d59e88442f2c","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":510,"y":200,"wires":[]}]

const lookup = {
    "ID of light1": "manCaveLight",
    "ID of light2": "patioLight",
    "ID of light3": "shedLed",
    "123456789011": "gardenLed"
};

if(msg.payload.data[0].on.on === true){
    msg.topic = lookup[msg.payload.data[0].id];
}else{
    msg = null;
}
return msg;

Only messages with ..on === true will be passed on all others return a null message.

Thank you E1cid,

Didn't know you could declare a constant that way, certainly makes the code more readable. Good call on nullifying the message.

Has given me some additional insights for sure

Thanks again for your input.

On the topic of philipshue-events has anyone noticed the node hanging on reporting events? Basically it'll send events just fine and then it just stops at some random point in the day. I'm having this happen multiple times a day now and the only solution I've found it to restart node-red.

Indeed, with node-red-contrib-huemagic there is a problem. Check out their git repository and you will notice you are not alone.

I disabled everything related to this node and instead am using this at the moment. It is not as straight forward as before mentioned node, however, manageable :slight_smile: ...

I switched from huemagic to @yadomi/node-red-contrib-philipshue-events quite some time ago. Unfortunately, that's also hanging on me now. Thanks for the link, I'll check it out tomorrow and see if that helps.

@DiverRich,
I'm currently running ver 1.4.2 philipshue-events with no issues. I see there is a new release but scared to update it :smiley:

yadomi has responded to an Issue rasied here (still) stops receiving of events · Issue #15 · yadomi/node-red-contrib-philipshue-events · GitHub Dont think its going to be a quick fix.

Thank you! It's good to know it's not just me. I was about to tear into my flows and probably just make everything worse. :smile:

@dgulliver I followed that link and used the array splitter that was suggested there. Fixed my issue completely. Thanks for the tip!
