In order to control u4171 using smart devices such as smartphones (or tablets) an App needs to be downloaded and installed. Please follow the instructions come with u172 to download and install the App.

Power on u172 before starting the APP. The user interface of the App is quite self-explanatory. Please find some key features as follows:

1.After power on u172 load the APP into smart phone and launch the APP. Tap “+” button at the top-left corner to bring up a screen “Add Device” (Fig. 7). Enter device ID and Password to add u172 to be controlled. Every u172 unit has a unique ID and the default password is 1234567. The password can be changed by the user once the initial setup is completed. The device ID can also be acquired by scanning the QR code on the device package.

After tapping “OK” button to refresh the screen the “Device List” screen will show up (Fig.8). If the setup is successful the device list screen will show the device info of u172 and the connection status as “Direct Control”

.

In case “Direct Control” status is not shown tap “Refresh” button (a circle with an arrow at the top-right-corner). Once “Direct Control” is confirmed u172 is ready to be directly controlled by the smartphone.

2.Once u172 is directly connected to the smartphone pressing “Menu “button (3 horizontal bars at the top-right-corner) to bring up a setup menu (Fig. 9). This menu lists a few more actions to be taken:

Modes: Set up ways to control u172 via internet router;

Password: Changepassword; and

Remarks: Make notes for the u172;
 

3.Tap “Modes” button to link u172 to a router on the “Modes” screen (Fig. 10). Enter the name of your router and Password of your router. Tap “OK” button to establish a connection and the LED indicator will be flashing.

Once the LED indicator stops flashing tapping “Refresh” button will bring in a change in the device’s status. There can be one of the following three different statuses:

Local network: Smartphone can control u172 via a router but the router is not connected to internet;

Internet: u172 is connected to a WiFi internet hotspot (router) and Smartphone can control u172 as long as it is connected to a WiFi internet hotspots; and

Internet/Local Network: u172 can be controlled over internet and locally within WiFi working distance.

Again if the setup is successful the device list screen will show the device info of u171 and the connection status as one of the connected statuses (Fig. 11).

4.Make sure u172 is connected to smartphone and tap u172 picture on the “Device List” screen to bring up an operation screen as shown in Fig. 12. The lamp can be turned on or turn off by tapping the control button in the center and a light bulb indicator at top left will be on or off accordingly. Sliding the round dot on the top left bar will adjust brightness of the lamp (20% to 100%).

On the setup menu screen (Fig. 9) two other buttons can be used for the following purposes respectively:

5.Change password: Tap “Password” button to change the default password to a user specific one.

6.Make notes: Tap “Remarks” button to make notes for the u172 such as “This is for living room” etc.

Reset u172 to Direct Control:

Pressing and holding the “Set Up” button for about 3 seconds until the LED indicator stops flashing. Tapping the Refresh button on the APP screen will switch u172 back to Direct Control.

Note: If there is something wrong when setting up a router connection please reset u172 back to Direct Control first before attempting to set up the router again.
