You can connect your Kisi hardware to the Wifi by using Electric Imp's BlinkUp™ technology. This allows you to transmit wired or wireless network credentials to the controller and readers via a series of light flashes to a photo-optical sensor on the Kisi device.

When connecting your hardware to the internet, you need to consider the following two features:

  • a receiver that receives network credentials
  • a status indicator that visualizes the controllers connectivity status.

The status indicator will blink in different color patterns based on its status condition. Use the table below to identify the color patterns your device’s BlinkUp status LED may signal.

BlinkUp codes


To identify the root cause of a failure, you need to look at the pattern being flashed at the point of failure, ie. the last pattern to flash before the LED is powered down.
