Initialization

Send 0x0032000000 to 0x1902.

Control

Change color:

Send 0xRRGGBBWW to 0x1601

• RR = red 00-ff
• GG = green 00-ff
• BB = blue 00-ff
• WW = brightness? 00-ff

Suction:

Send 0xXXYY to 0x1401

• XX = suction intensity (0x80-0xff)
  • The device does respond to lower values than 0x80, but that's the starting intensity in the official app.
• YY = time to turn on for (0x01-0xff)
  • 0x01 = ~0.05s, 0xff = ~12.75s
  • Command can be repeated before the previous command finishes to keep the suction going
  • Suction remains held after the time is up until the release command is sent

Release:

Send 0xXXYY to 0x1402

• XX = speed of release?
• YY = time spent releasing suction?
  The official app generally sends the same values to the release command as it sent to the suction command.
