Magic Hue lightbulb CLI utility

This repository includes two scripts:

The setup.py script allows the user to connect the "MagicHue" lightbulb to their Wi-Fi. The magichue.py script provides an easy API for the "MagicHue" lightbulbs.

Installation

  1. Plug in your MagicHue lightbulb and turn it on. It will start flashing different colors.
  2. Connect to its wifi (something like LEDnetE1234B)
  3. Run the setup.py script, providing your SSID and your WiFi password: python3 setup.py -ssid MyWifiEndpoint -pswd MyAwesomePassword

If the script worked, your lightbulb will turn green within a few seconds.

Note: Currently the script is automated for WPA2PSK / AES only. Modify it if your WiFi uses a different mode and encryption.

Usage

Once your lightbulb is on your network, you can use the magichue.py script with the following arguments:

  -h, --help  show help message and exit
  -ip         provide the IP for the lightbulb; i.e. -ip 192.168.2.2
  -raw        accept colon separated raw hex string; i.e. -raw 71:23:0f
  -rgb        accept comma separated rgb values; i.e. -rgb 100,155,75
  -warm       accept value of warm white (0-255); i.e. -warm 150
  -power      accept 'on' or 'off'; i.e. -power on
  -status     get the bulb's status

The user must provide the lightbulb's IP address and either comma separated RGB values or a colon separated list of HEX values. An updated list of known combinations and rules of HEX values can be found below.

RGB Example:

This will set the lightbulb to be red: python3 magichue.py -ip 192.168.2.2 -rgb 200,0,0

WARM WHITE Example:

This will set the lightbulb to half power of warm white: python3 magichue.py -ip 192.168.2.2 -warm 123

RAW Hex Example:

This will turn the lightbulb on with its last setting: python3 magichue.py -ip 192.168.2.2 -raw 71:23:0f

Understanding the bulb's HEX codes:

I've been able to sniff a few codes, which the app sends to the lightbulb. The structure of the hex list seems to follow a pattern. The first bit defines the type of action. Then follow informational bits, which define colors, brightness, etc. The entire list is followed by a checksum bit, masked by 255. For example, this is the broken down list for turning the bulb on:

Action bit Body bit list Finish bit Checksum bit
71 24 0f a4

And here is how the data looks for magenta / purple color:

Action bit Body bit list Finish bit Checksum bit
31 ff:2f:ff:00:f0 0f 5d

It's important to note that this script will calculate the checksum bit. You MUST NOT include it in the -raw argument.

There are several different types of commands (Action Bits) that the bulb seems to accept: 31 - Color options 61 - Pulse / gradual options 71 - Power options 81 - Status options

The 31 and 61 action bit commands seem to follow a structure in the body bit list: 31:RR:GG:BB:?BRIGHTNESS?:?COLORTYPE?:0f 61:COLOR(S):BRIGHTNESS:0f

The following examples can help you futher undertand the structure of the body bit list:

HEX examples Note that the final checksum bit is not included here. The script will add it automatically.
