The function in node-red still doesnât work however and says âerror load mediaâ
var urls = ["/home/pi/.node-red/public/alert1.wav",
"/home/pi/.node-red/public/alert2.wav",
"/home/pi/.node-red/public/alert3.wav"]
msg.url = urls[Math.floor(Math.random() * urls.length)];
msg.contentType = "audio/vnd.wav";
return msg;
But if I change it to this instead it now works
var urls = ["http://192.168.0.4:1880/alert1.wav",
"http://192.168.0.4:1880/alert2.wav",
"http://192.168.0.4:1880/alert3.wav"]
msg.url = urls[Math.floor(Math.random() * urls.length)];
msg.contentType = "audio/vnd.wav";
return msg;
This means I can now delete those 3x HTTP nodes as they are no longer needed anymore.
OK this is my final Node-Red Flow

I just need to record some audio files now and see if it actually works and stops him barking?
Thanks for your help again @ElCid

As always love to help.
note - you can use the static folder as a local file server to.

Well the whole setup works perfectly, just tested it putting the dog in the kitchen. The tablet in the lounge detects him barking each time and it triggers the random .wav files to play on the Google Home speaker in the kitchen, all working very nicely !
However the dog pretty much ignored my voice recordings and continued to bark and scratch at the door. Heâs not use to being left on his own even for two damn minutes, need to do a lot of training with him I think.
Might try a low or high frequency noise next on a .wav file that or a muzzleâŠ
In the Cast node you can specify the volume, I have set it to 70.
This works and increased the volume to 70 when the flow is triggered.
I would like to set the volume back down again after to say 40. But not sure how to do this.
I tried adding another Cast node after the first one with its volume set to 40 but it didnât work.
Add a pause. This kind of devices usually needs some interval between commands.
Using a change node try feeding one of the below into a cast node, with just ip and port configured.
msg.lowerVolumeLimitormsg.payload.lowerVolumeLimitwill set the volume to this value, if the current volume is below this value.msg.upperVolumeLimitormsg.payload.upperVolumeLimitwill set the volume to this value, if the current volume is above this limit.
Hi
The msg.payload.lowerVolumeLimit works when the flow is run it increases the volume of the Google Home speaker before playing the .wav file.
However I am not sure how to then decrease the volume back down again after the .wav file has finished playing.
I tried something like this but it doesnât work.
does it not work if you have the casts in line with a small delay between e.g.
the last change node before final cast set like this
[{"id":"8201bedc.782588","type":"change","z":"a8699ddc.35b368","name":"vol down","rules":[{"t":"set","p":"upperVolumeLimit","pt":"msg","to":"40","tot":"str"},{"t":"set","p":"ip","pt":"msg","to":"192.168.1.20","tot":"str"},{"t":"set","p":"port","pt":"msg","to":"8009","tot":"str"}],"action":"","property":"","from":"","to":"","reg":false,"x":770,"y":180,"wires":[["5f71942a.6bb15c"]]}]
Hi
Iâve tried what you suggested the volume is increased to 50 then the .wav file plays.
However after the .wav file has finished playing nothing further happens, the volume is not decreased back down to 30 as I have set in the Volume Down function.
what is the full debug message after the first cast?
I donât know I just changed the function nodes.
Instead of using msg.payload.lowerVolumeLimit and msg.payload.upperVolumeLimit I set both the function nodes to just use msg.payload.volume instead.
The first volume up function sets the volume to 50 then the .wav play. The second function then sets the volume to 30 but the .wav then plays again at the lower volume level.
So I donât think they can all be in a single line / flow.
yes i think its possible , maybe that a property still exists. post your function nodes.
Volume Up Function:
Volume Down Function:
Nice idea but it is still playing the .wav file for a second time at the lower volume level.
It doesnât seem to be deleting the url and contentType
I Deployed and restarted All Flows.
Ok i reworked the original function
no need for all those nodes, the cast node needs no settings all settings are in function node.
It should? send a cast then wait 3 seconds(editable in function node) and send a volume change cast.

Hi
Thanks for this !
Here is the code I now have in the function block.
var urls = ["http://192.168.0.4:1880/alert1.wav",
"http://192.168.0.4:1880/alert2.wav",
"http://192.168.0.4:1880/alert3.wav",
"http://192.168.0.4:1880/alert4.wav",
"http://192.168.0.4:1880/alert5.wav"]
msg.payload.url = urls[Math.floor(Math.random() * urls.length)];
msg.payload.volume = 50;
msg.payload.contentType = "audio/vnd.wav";
msg.payload.ip = "192.168.0.19";
msg.payload["port"] = 8009;
node.send(msg);
setTimeout(function(){
delete msg.payload.url;
delete msg.payload.contentType;
msg.payload.volume = 30;
node.send(msg);
}, 3000);
return;
When I initiate the Flow it changes the volume on the Google Home speaker up to 50% but then right away it changes the volume down to 30% and then the .wav file plays at the lower volume.
I then change 3000 to 30000 aka 30 seconds and now it seems to be working perfectly.
It plays the .wav at 50% and then 30 seconds later lowers the volume to 30%.
Thank you very much !
