After WiFi is powered down; sound is muted - Jasky - 03-21-2025

Hi,

I have a multi room set up. The sender and receivers are all RPi 4.

Moode version: 9.0.0

I turn my wifi off whilst I sleep, the wifi is off until 6am. When I wake and hit play on some music it's muted by default. I need to go into the receivers in the ui (img attached) and toggle the check boxes to get the sound  to unmute.

Ideally, I'm after a way of doing this action programmatically, so I can fire that on a cron in the morning. What is the best way to toggle that mute action without resorting to beautiful soup (parsing the html). The relevant logs to that action are the last few lines (I think) from the debug log below.


Code:

This project is hands down one of my favourite opensource projects I've come across. So impressive, I can't give my thanks to all the contributors enough.

Thanks for any help,

RE: After WiFi is powered down; sound is muted - Tim Curtis - 03-22-2025

Its undocumented but try these REST API commands for controlling the receiver

Code:
http://HOSTNAME_OR_IPADDRESS/command/?cmd=trx_control -rx Off
http://HOSTNAME_OR_IPADDRESS/command/?cmd=trx_control -rx On

# Maybe a delay between them is needed if running consecutively ?

A cURL version is below - not tested but should work.

Code:
curl -G -S -s --data-urlencode "cmd=trx_control -rx Off" http://HOSTNAME_OR_IPADDRESS/command/

The file that receives them is /var/www/command/index.php
The file that executes them is /var/www/util/trx-control.php

Thanks for the speedy reply Tim. That API does the trick and I didn't need to add a delay between the calls. I run this daily using a systemd timer, here's the code for anyone who finds themselves needing it in the future:

Code:
#!/bin/bash

set -e
set -o pipefail

HALL=192.168.xxx.yyy
LIVING_ROOM=192.168.xxx.yyy
KITCHEN=192.168.xxx.yyy

SERVERS=($HALL $LIVING_ROOM $KITCHEN)

for server in "${SERVERS[@]}"; do
   curl -G -S -s --data-urlencode "cmd=trx_control -rx Off" "http://$server/command/"
   curl -G -S -s --data-urlencode "cmd=trx_control -rx On" "http://$server/command/"
done

exit 0
