Getting started
Congratulations on your purchase of this powerful WIFI Door/Window Sensor. Once the magnet (smaller part) is moved away from the reed
switch (built into the larger part) or both parts close again, the unit will send an alarm signal to your smart phone via your home/business
WIFI connection. Such signal is selectable as an Alarm Sound + Notification, Notification Sound + Notification or just a silent Notification. This
product works together with your smart phone and internet via WIFI. Please check that your smart phone is either an Android or IOS (iPhone)
and that the latest firmware has been installed. Please also check that your WIFI router is working properly and that its operating manual
confirms that it operates on 2.4 GHz with WPA/WPA2 encryption.
Installing the APP
click OK
Before powering up the Sensor, please install our free ‘NEXUSHOME ‘ APP onto your phone. The APP is available in an IOS version on the
Apple App Store and an Android version on the Google Play Store. Ensure your phone is connected to WIFI to complete account setup.
Once downloaded, click and open the APP. The following message will appear. Please click OK.
Now complete your User Profile by inputting your email address and a 6 digit or longer Password, click the REGISTER button, check your
email and click the link in the email from “Netify” to complete registration.
Setting up your DEVICE
connect WiFi
click “Add Device/WiFi Setting”
choose Wireless Pairing
Go to the location in the Building where you eventually wish to install the Sensor. Look at your smart phone and ensure you have a good
and steady WIFI connection there. Now, exit the APP, open SETTINGS on your smart phone and click “Wi-Fi”. Check what is showing. If
you just have a main Router, it should be showing its reference name (or SSID). Each Router or Extender has its own unique reference
name or SSID. However, if you have a network with one or more extenders, it may also be showing, underneath, under “Choose a
Network”, the SSID of an overlapping Extender, as in the picture 1 above. In this case, check whether you are closest to the main Router or
to an Extender and manually select, if necessary, the alternative closest/strongest SSID. THIS IS VERY IMPORTANT. The Sensor will only
communicate Alarm signals to the WIFI Router or Extender that you are about to “pair” it to so it is essential that you pair it to the closest/
strongest Wi-Fi signal.
Re-Open the APP and click
PROFILE at the bottom of the opening HOME page. This will take you to the APP’s SETTINGS Page. Click
Please select “Wireless” at the bottom right hand side of the Page.
insert two AAA batteries
enter the name of WIFI and password
Move the Sensor temporarily, right next door to the Router or Extender that you are pairing to. Carefully unscrew and open the battery
cover. Insert two new, good quality Alkaline AAA batteries, ensuring correct polarity. The Sensor will now automatically enter “Pairing
Mode”. You have 30 seconds to start the Pairing Process.
Go back to the App on the “ADD DEVICE/WIFI SETTING” page. You will see the same SSID of the Router/Extender that you selected in
your phone’s WIFI Settings at the top of the Page. Enter the password of that Router or Extender and press PAIR NEW DEVICE.
The Sensor will now start pairing to the Router or Extender and you will see the wheel whirling. It can take up to 60 seconds for a “pairing
successful” message to appear. If you see the message “time out, try again”, disconnect the batteries from the sensor, reconnect them
to enter pairing mode again and repeat the process. If this error message continues, double check that the SSID on this page and the
password both match the Router or Extender to which you are attempting to pair the Sensor to. Once pairing is successful, you can now
close the battery door. Mount the Sensor onto the Door or Window using the double sided tape provided, ensuring that the arrows on
the both the magnet and the main unit align and that the magnet is no more than 5mm apart from the main unit.

Do not place any other magnets or magnetized materials close to a Sensor as this could cause a false trigger.
Make sure your WIFI router and its signal strength cover all the Sensors locations. Please note that a WIFI signal may not penetrate
through concrete walls or solid doors and that, if it does, it is usually SEVERELY reduced. You may therefore need to add one or more WIFI
Repeaters to increase signal coverage. If you do this, then ensure that individual devices are paired to the closest Repeater or Router.
Since all Router/Repeater SSID’s are different, you must ensure that the Sensor is paired to the correct SSID (see setting up your WIFI
Device above).
After installing a Sensor, please test it at least a couple of times to check the performance.
Trouble Shooting
Check whether the Sensor has enough battery power. Always use new, good quality, Alkaline batteries.
If there are too many WIFI connections around your Sensor, turn them off to avoid any disturbance and pair again.
Check that the router is working properly and that it operates on 2.4GHz
Check that the SSID and password are correct.
Check whether the Sensor is within coverage of your WIFI router/repeater. Move the Sensor or Router to a different location.
Check that the router is working properly
Check the power level of the tag. If it shows a battery low icon in the APP, please replace the batteries.
Check that the magnet and reed switch are aligned correctly with the arrows directly opposite each other.
Check that the distance you have mounted the magnet away from the built-in reed switch is no more than 5mm.
Do not drop, disassemble, open, crush, bend, deform, puncture, shred, microwave, incinerate, paint, or insert foreign objects into the
Sensor. Such actions could result in an electric shock. Clean the Sensor only with a dry cloth.
Do not expose the Sensor to extremely high or low temperatures or leave them in direct sunlight for extended periods of time.
Do not leave the Sensor near open flames such as cookers, candles or fireplaces.
It’s dangerous if you replace batteries incorrectly or with the wrong polarity. You should only use the same or equivalent type of battery to
replace a damaged or drained one. The Battery should not be exposed to an overheating environment such as extreme sunshine or fire.
Always use a good quality Alkaline battery for best results.
