# What's this project?

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

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

It comes with a with a simplistic but neat **Web UI** and a simple (but hopefully convenient) **Rest API**.

| Controlled by Stream Deck with REST API | Light roll |
| --- | --- |

# Web UI

A very simplistic but neat UI is available on port `80` (thanks @nicolaeser).   
Default hostname is `igox-busylight`.

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

| What an neat UI ! 😄 |

# BusyLight Buddy companion app

[BusyLight Buddy](https://code.igox.org/iGoX/busylight-buddy) is a free, open-source multiplatform companion app to control your BusyLight from your phone or computer — no browser needed.

Available for **iOS**, **iPadOS**, **Android**, **macOS**, and **Windows**.

It features quick status presets, a custom color picker with saveable presets, a brightness slider, and background polling to keep the UI in sync with the device.

# Stream Deck plug-in

You can download the Stream Deck plugin to control your BusyLight:

## JSON objects

### `color` object

```json
{
  "r": 255,
  "g": 0,
  "b": 127,
  "brightness": 0.5
}
```

`r`: RED color | integer | [0 .. 255]  
`g`: GREEN color | integer | [0 .. 255]  
`b`: BLUE color | integer | [0 .. 255]  
`brightness`: LED brightness (optional) | float | [0.0 .. 1.0]

### `brightness` object

```json
{
  "brightness": 0.5
}
```

`brightness`: LED brightness | float | [0.0 .. 1.0]

### `blink` object

```json
{
  "isblinking": true,
  "frequency": 2,
  "duration": 5.0,
  "remains": 3.2
}
```

`isblinking`: whether the BusyLight is currently blinking | boolean  
`frequency`: blink frequency | integer | Hz  
`duration`: total blink duration | float | seconds | 0 = endless  
`remains`: remaining blink time | float | seconds | 0 if endless  

### `status` object

```json
{
  "status": "<STATUS>"
}
```

`<STATUS>` : `on` | `off` | `available` | `away` | `busy` | `colored` | `blinking`

# MuteDeck integration

The `POST api/mutedeck-webhook` endpoint aims to collect [MuteDeck](https://mutedeck.com/help/docs/notifications.html#enabling-the-webhook-integration) 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.

# Firmware installation

**(1)** Flash your ESP32 with [Micropython](https://micropython.org/download/ESP32_GENERIC/) **v1.24.1**.

**(2)** Install [microdot](https://microdot.readthedocs.io/en/latest/index.html) **v2.0.6** library on the ESP32. This can easily be done using [Thonny](https://thonny.org):

| Tools > Manage plug-ins | lib selection |
| --- | --- |
| ![lib-menu](resources/images/lib-menu.png) | ![lib-install](resources/images/lib-install.png) |

> ⚠️ **Compatibility note:** MicroPython v1.27 is **not compatible** with Microdot due to breaking changes in the underlying ESP-IDF v5.5. Use MicroPython **v1.24.1** with Microdot **v2.0.6**.

**(3)** Edit the `WIFI Configuration` section in the [boot.py](ESP32/boot.py) file.

**(4)** Copy the content of [ESP32](ESP32) folder with the modified `boot.py` file to the root of your ESP32 file system. Again, can easily be done using [Thonny](https://thonny.org):

![file-copy](resources/images/file-copy.png)

**Done!**
