A script to control MagicLight and other cheap wifi rgb lights

magiclight.py

import socket, time
s = socket.socket()
address = ''
port = 5577
r = 0
g = 255
b = 0
keybit = "31".replace(':', '').decode('hex')
keybit += chr(r) + chr(g) + chr(b)
keybit += "00:f0:0f".replace(':', '').decode('hex')
keybit += chr(sum(bytearray(keybit))%256)
print sum(bytearray(keybit[:-1]))%256
print keybit.encode('hex')
try:
    s.connect((address, port))
    s.send("81:8a:8b:96".replace(':', '').decode('hex'))
    s.recv(1000)
    s.send("10:14:0f:08:0d:05:16:15:04:00:0f:8b".replace(':', '').decode('hex'))
    s.recv(1000)
    s.send(keybit)
except:
    print("Could Not Connect (They are finnicy!)")

Cool, this works! 👍

Any idea how to make this work in 3.4?

I tried replacing .decode with codecs.decode(___original_code___, 'hex'), but am still getting errors. I tried looking into it more, but the conversion process in your code is a bit over my head. I'm not quite sure what result the sequence of actions is leading to.

Current Error:

Traceback (most recent call last):
  File "C:\Users\Fico\Desktop\MagicLightTest.py", line 11, in <module>
    keybit += chr(r) + chr(g) + chr(b)
TypeError: can't concat bytes to str
[Finished in 0.2s]

Current Code:

import socket, time, codecs

s = socket.socket()
address = ''
port = 5577
r = 0
g = 255
b = 0

keybit = codecs.decode("31".replace(':', ''), 'hex')
keybit += chr(r) + chr(g) + chr(b)
keybit += codecs.decode("00:f0:0f".replace(':', ''), 'hex')
keybit += chr(sum(bytearray(keybit))%256)
print (sum(bytearray(keybit[:-1]))%256)
print (keybit.encode('hex'))
try:
        s.connect((address, port))
        s.send(codecs.decode("81:8a:8b:96".replace(':', ''), 'hex'))
        s.recv(1000)
        s.send(codecs.decode("10:14:0f:08:0d:05:16:15:04:00:0f:8b".replace(':', ''), 'hex'))
        s.recv(1000)
        s.send(keybit)
except:
        print("Could Not Connect (They are finnicy!)")

I also tried changing line 11 to:

keybit += codecs.encode(chr(r) + chr(g) + chr(b),'hex')

for which I get:

Traceback (most recent call last):
  File "C:\Python34\lib\encodings\hex_codec.py", line 15, in hex_encode
    return (binascii.b2a_hex(input), len(input))
TypeError: 'str' does not support the buffer interface

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\Fico\Desktop\MagicLightTest.py", line 11, in <module>
    keybit += codecs.encode(chr(r) + chr(g) + chr(b),'hex')
TypeError: encoding with 'hex' codec failed (TypeError: 'str' does not support the buffer interface)
[Finished in 0.2s]

I found this project to be extremely helpful: https://github.com/beville/flux_led

This worked for me! Took a while to find the IP address. My light bulb had a hostname like HF-LPB100-ZJ####, incase anyone comes here looking for how to get the ip address. I just had to try all 20 wireless clients until I found it haha.

Thanks for this!

If you're looking for the IP Addr of the connected device you can look in the following location:

1. Click on the gear icon in the top left
2. Select device settings
3. Select the device you want to get the information for
4. Click Device Information
5. Fourth item down is the IP for that device

Also, removing lines 16 through 19 allowed the changes to the light to be almost instant. With the code listed above the delay was about a minute and caused the updates to randomly fail.
