#InternetOfThings
Home Automation App (User’s Guide)
There are two modes of operation:
- OFF-LINE: Select this if you are controlling the appliances from within the home.
- 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“
