Hello

I have node red running on an Ubuntu server.

I also have a door bell which communicates to node red via MQTT (Ubuntu) and a remote dashboard on an iPad (running safari browser).

When the button is pressed, node-red senses it correctly, but I would like to play an mp3 I have on Ubuntu server on the iPad.

What's the easiest way to do this?

I may be wrong but browsers don't permit audio without user interaction.

Instead you could use something like an MQTT app that triggers actions on your device. For example [this app](https://www.easymqtt.app/about) says it can trigger Siri shortcuts so in theory could play a sound.

Out of interest, is this doorbell a commercial product or home made? Could you share details please?

Really? What if I host the mp3 file on a HTTP server, can I then trigger the UI dashboard to play that mp3 file when an event occurs?

Yeah home made, I couldn't find something that suited my purpose. I have a Shelly 1 running on a 12VDC supply then to a simple doorbell button (dry contact). The Shelly 1 detects the doorbell button and sends an MQTT message to node red. I was hoping my iPad could replace the doorbell chime and play a song when someone presses the doorbell.

Further to this, I have it working by pulling the mp3 file using a HTTP request node. This works on all PCs running chrome on my network. However I cannot get the file to play in Safari on my iPad.

Does anyone know if there's a setting to enable this in Safari?

Or any other browser for that matter? I really don’t want to install a chime and the iPad is the central control screen for the house.

ok some updates, I've managed to play audio files when clicking a button in the dashboard with this script in a template node:

```auto
<script>
$('button').click(function() { new Audio("http://address.com/thismp3.mp3").play();
})
</script>

```

Is there a way to trigger this mp3 with a function node? I want it to play when it receives an MQTT message from the Shelly 1

Thanks for the reply, but this is now beyond me unless someone knows how to integrate this function into node red?
