INSTALLATION 
Please follow the steps as detailed in the order below 
for best results. 
1 TEST DEVICE FOR OPENER COMPATIBILITY  
Use the included single wire or take a straightened-out paper clip 
and put each end to the same terminals as the wall button wires 
are terminated to.  By doing so, your garage door should activate.  
Check out Nexx Garage website http://nexxgarage.com/videos for 
video of this test.   
If this test fails, your device may not be compatible so STOP and 
contact support@nexxgarage.com for an adapter that can get 
Nexx Garage to work with your garage. 

7 
2  INSTALL MOBILE APP & CREATE ACCOUNT  
First make sure you are on your home Wi-Fi and NOT 
mobile Wi-Fi.  As Nexx Garage requires a good Wi-Fi signal 
to work properly, and if your Wi-Fi is weak, a Wi-Fi extender 
is highly recommended. 
1) Download and install "Nexx Garage" app from Google Play 
Store or Apple App Store. 
2) Launch "Nexx Garage" app. 
3) From Login screen, tap "Create Account".  Enter required 
fields and tap “Register” located at upper right corner. 

8 
3 REGISTER DEVICE & SET UP WI-FI 
1) Plug in your Nexx Garage device.  The LED light from the 
device should be solid green. 
2) Log in with your newly created account and tap  
menu->Register Devices.  Then tap “+” and “Yes, light is 
steady green”.  
Once your device is registered, follow the onscreen wizard setup 
process or as detailed out below to connect the Nexx Garage Wi-
Fi to your home Wi-Fi network. 
CONNECT TO NEXX GARAGE WI-FI NETWORK 
1) Switch to your Wi-Fi Settings and select the Nexx Garage 
Wi-Fi Network. 
2) If prompted, enter 12345678 as password and tap 
join.  This may not be necessary for newer firmware. 

9 
CONNECT TO YOUR WI-FI NETWORK 
1) Switch to Nexx Garage app.   
2) Select your home Wi-Fi network and enter the password. 
3) Verify your Wi-Fi network and password. 
4) Save your configurations. 
After applying these settings, your Nexx Garage device will reboot. 
The LED light should blink several times.  When the LED light is off, 
your device has successfully connected to your Wi-Fi network. 
Note: 
If your device continues to blink, press the reset button on the device 
for 5 seconds until the LED light becomes solid green.  Then repeat 
the above described process. 

10 
REGISTER TO CLOUD SERVICE 
1) Enter a name for your device. 
2) Tap “Register to Cloud”. 
Note: 
If there is an error registering to Cloud, make sure your phone is on 
your HOME network and try again. 

11 
4  TEST SENSORS FOR NOTIFICATIONS 
This step is to verify if the sensors are working and you are getting 
notifications when the garage door is opened or closed.  
1) Connect the sensor with the connector to the Nexx 
Garage device connector.  

12 
2) Tap and hold sensors together.  LED light should blink 
and app should show door is closed. 

13 
3) Wait for 3 seconds then move the sensors apart.  LED 
light should blink and app should show door is open.  
If you are not getting the proper notifications, your sensors may 
be defective so STOP and contact customer support at  
support@nexxgarage.com, and we will send you new sensors. 
If both the Compatibility Test and the Sensors Test succeed, 
then continue with the remaining installation steps. 

14 
5  MOUNT THE DEVICE 
1) Clean the surface on top of your garage door opener 
before using the double-sided tape to secure the device.   
2) Mount  the device on  top  of  your  garage  door  opener 
(GDO) near the  GDO terminals using the double-sided 
adhesive tape.   
3) Make sure the device is close enough to the terminals of 
the GDO so that you can connect wires to the device to 
the GDO. 

15 
6  CONNECT THE DEVICE TO YOUR OPENER 
1) Locate the two exposed wires coming out of the Nexx 
Garage device. 
2) Connect these two exposed wires to your garage door 
opener (GDO).  Connect them to the same wire as your 
wall  console  or  manual  button  to  open/close  the 
garage door (see diagram below). 

16 
3) If a wire is currently connected to the terminal of the 
GDO, take out the existing wire from the GDO terminal.  
Twist the two wires together and reconnect it back to 
the GDO.  

17 
7  POWER UP NEXX GARAGE DEVICE 
1) Plug the power cable of the device into an outlet.   
2) The LED light from the device should blink several times 
and turn off.  Once the LED light is off, this will indicate 
that the device has successfully connected to your Wi-Fi 
network. 
If you cannot get the LED light to be off, contact us at 
support@nexxgarage.com or go to 
http://www.nexxgarage.com/support/ for troubleshooting tips.  

18 
8  MOUNT THE SENSORS 
1) The sensors have 2 parts.  One is connected to the cable 
while the other is not. 
2) Both sensors must be mounted parallel to each other as 
shown in the diagrams below, and they must be 1/8 to 
1/4 inch apart, not touching.  It is VERY IMPORTANT that 
the sensors are apart within this guideline to ensure 
proper notifications. 
 OR 

19 
3) Mount the sensor that is connected to the cable to the 
center  of  the  wall  adjacent  to  the  garage  door,  just 
above the garage door.  Use the included double-sided 
tape to secure the sensor.  If you have screws, you may 
use that instead. 
4) Mount the other sensor (the one NOT connected to a 
cable)  on  center  top  of  the  garage  door  using  the 
double-sided tape.  If  you have screws, you  may  use 
that instead.  

20 

21 
5) Secure  the  remaining  wires  along  the  walls  and  ceiling 
using the included double-sided tape to avoid any moving 
parts of the door.  You can also use other alternatives to 
secure the cable such as cable clips or staples. 

22 
9  TEST MOBILE APP FOR NOTIFICATIONS 
At this point, the app should indicate that you are connected to 
the device and that the door is currently closed. 
1) Press the garage door icon.  Your garage door should be 
opening and the app should indicate that your garage 
door is opened. 

23 
2) Press the garage door icon again.  Your garage door 
should be closing.  When the garage door is completely 
closed, the app should indicate that your garage door is 
closed.
