Abstract: Various techniques are provided to facilitate the identification of devices, such as smart light bulbs, ceiling fans, security systems, garage doors, and other devices whose functions may be automated or controlled remotely. Identification is done through visible light using existing light sources on target devices and existing image sensors on control devices. In one example, a user may point the camera sensor on their mobile phone at a smart light bulb. This light bulb is turning on and off faster than the human eye can detect, and it is sending a coded message that can be received and decoded by the camera sensor on the mobile phone. The light bulb is identified by the mobile phone, and the user may choose to turn the light on or off through the mobile phone's connection through a data network to the smart light bulb.
