Home Automation App (User’s Guide)

There are two modes of operation:

  1. OFF-LINE: Select this if you are controlling the appliances from within the home.
  2. ON-LINE: Select this if you are controlling the appliances from outside the home.

When OFF-LINE mode is selected, select the URL from the drop-down menu that appears on the device’s LED Screen.

Click the Button of each device to “Turn On” and Long Press that button to “Turn OFF
