Toggle Mute on a Bang & Olufsen Mozart Product with BLI

Introduction

This tutorial explains how to create a simple BeoLiving Intelligence macro to toggle the mute state of a Bang & Olufsen Mozart product, such as a Beosound Balance or Beosound Emerge. This can be useful for connecting a mute button on a keypad or third-party remote to your Mozart product.

How to set it up

To set up the mute toggle macro, follow these steps:

Open the BeoLiving Intelligence admin panel.
Go to the Macro tab.
Create a new Macro.
Add a trigger for this macro, such as a button press on your keypad or third-party remote, as an event.
Press the “Convert to code” button in the commands table.
Copy the entire code in “The code” section below.
Paste the code into the code text area of the Macro.
Replace _targetProduct_ with the actual address of your Mozart product in the SETTINGS section.
Test the macro by triggering the event. The macro should toggle the mute state of your Mozart product.
