What's this project?

Let people know if they can bother you with light signals!

A simple to build, nice looking, portable DIY Busy Light.

It comes with a with a rudimentary (and ugly) Web UI and a simple (but hopefully convenient) Rest API.

Controlled by Stream Deck with REST API	Light roll

Web UI

A very simplistic (and ugly) UI is available on port 80.
Default hostname is igox-busylight.

You can try to reach the web UI @ http://igox-busylight.local.

What an ugly UI ! 😄

Stream Deck plug-in

You can download a Stream Deck plugin to control your BusyLight here.

I will (hopefully) publish it to the Elgato Market Place soon.

MuteDeck integration

The POST api/mutedeck-webhook endpoint aims to collect MuteDeck webhook callbacks.

It will automatically switch to the BusyLight in:

• busy mode (Red color) when entering a meeting with Mic ON and camera ON.
• away mode (Yellow color) when entering a meeting with Mic OFF and camera ON.
• away mode (Yellow color) if the mic is muted during a meeting.
• available mode (Green color) when exiting/closing a meeting.

(3) Edit the WIFI Configuration section in the boot.py file.

(4) Copy the content of ESP32 folder with the modified boot.py file to the root of your ESP32 file system. Again, can easily be done using Thonny:

Done!
