Recently I purchased MagicLight WiFi Smart LED RGB Light Bulbs to brighten up my room. After installing them and playing with the android app I noticed there was no Web Gui or portal to control them. So I decided to take action and create one myself here. I wanted to do this because I was annoyed of always pulling my phone out to change the lights. This way I could run it on a local server and just pull up a local page to control them.
The first action step was to figure out how to communicate with them. Having prior networking experience I assumed it was going to be over some TCP protocol so I decided to install a packet collector on my phone. Doing so I collected a bunch of data and started to decipher the data that was collected.
After looking it over I quickly noticed the following below:
The lights communicate by TCP packets over port 5577.
To turn on you’ll send 71230fa3
To turn off you’ll send 71240fa4
To change a color its 31 + (HEX Color Code) + 00F00F(magic hex) + checksum(sum of all bytes % 256) ei: 3100FF0000F00F2E
I used the socket class that came with rails to communicate with the lights via TCP.
The app i created below contains much of the same functionality as the MagicHome Pro app via Android. I am still adding more everyday.
Now my life has become much easier as I don’t always have to pull out my phone to control my lights.
