Pi 5 watchdog on Chrome when stop play audio and send e-mail

Support Raspberry Pi
1

Hi,
I have a raspberry pi 5 and I would like this:
1- Open a Full Screen web page with Chrome.
once the page is opened on my site the audio will start automatically. I managed this part with tutorials on the internet. It’s functional
But,

2- In Chrome, I want to check that the audio is playing and if it has stopped, send an email and restart the pi5.

:slight_smile:
Thank’s

Hi @daniel282384, welcome to the forums!

Glad to hear you’ve got step one working already! How exactly did you do this? It may narrow or broaden our options depending on the libraries and methods used, so more information on this would be super helpful.

My initial thoughts are that you may be able to use a watchdog application paired with some sort of resource monitor, that depends on exact configuration though.

Hi Daniel,

There are a couple ways you can set your script to be always on. The easiest is to have a script that won’t end and to run it when you boot your Pi. In your script set a loop that will check for audio and if it can’t detect it send an email, some delay for it to send, and then reboot your Pi.

Here are some methods that you can use to run a script when your Pi boots.

Hi @daniel282384,

It’s not quite possible for us to be able to setup for you as it requires it to be setup on the device and user that you want it to run on.

The link Jack sent through has fairly simple steps to follow to be able to get it up and working.
If you’re getting stuck you can ask for help.
