# Python Utility for Logitech Litra Glow

## Introduction

After purchasing a [Logitech Litra Glow](https://www.logitech.com/en-us/products/lighting/litra-glow.946-000001.html) I was unable to find any support for linux. This project attempts to reverse-engineer the basic functionality of the litra pro so that we can control it via USB without using the physical buttons on the device.

## Status

|Date|Description|
|-----------|----------------------------------------------------------|
| 2/2/2022  | Implemented an initial utility library and CLI|
| 2/1/2022  | Successfully reverse engineered USB calls to turn on / off the device, set the brightness and set the temperature. Created a simple standalone demo - `litra-demo.py`


## Setup

```bash
# Create a udev role to grant permission to access the light
sudo echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="046d", ATTR{idProduct}=="c900",\
           MODE="0666"' > /etc/udev/rules.d/82-litra-glow.rules
```

## Running the demo (DEPRACATED)

This has been tested on Fedora 35

```bash
git clone https://github.com/kharyam/litra-driver.git

cd litra-driver

python -m venv .venvs/default
source .venvs/default/bin/activate
pip install pyusb fire
python litra-demo.py
```

## The CLI

The log level can be adjusted by setting the environment variable `LITRA_LOGLEVEL` to one of the following:
* CRITICAL
* ERROR
* WARNING
* INFO
* DEBUG

```
NAME
    lc

SYNOPSIS
    lc COMMAND

COMMANDS
    COMMAND is one of the following:

     on
       Turns on the Litra Glow

     off
       Turns off the Litra Glow

     brightness
       Sets the brightness level of the Litra Glow

     temp
       Sets the temperature level of the Litra Glow
```

Sample Usage
```bash
lc power on
lc brightness 1
lc brightness 100
lc temperature 2700
lc temperature 6500
lc power off
```

## Development
