  • When removing cover for battery change - electrostatic discharge can harm electronic components inside.
  • Always mount indoors as the sensor is not waterproof.
  • Do not place the sensor close to magnetic or electromagnetic fields. This device includes a magnet. The magnet creates a magnetic field that may cause damage to computer hard drives, magnetic cards, data storage devices, hearing aids and speakers e.g. Therefore, we strongly advise you to never position the magnet close to electronic  devices.

Join to Network

  1. Open the casing of the device by pushing the fastening on top of the device to remove the front panel from the back cover. 
  2. Insert the enclosed batteries into the device, respecting the polarities
  3. Close the casing
  4. The entry sensor will now start searching (up to 15 minutes) for a Zigbee network to join.
  5. Make sure that the Zigbee network is open for joining devices and will accept the entry sensor.
  6. While the entry sensor is searching for a Zigbee network to join, the red LED is flashing.
  7. When the red LED stops flashing, the entry sensor has successfully joined the Zigbee network.


  • Place the sensor indoors at a temperature between 0-50°C.
  • The magnet has to be placed on that side of the sensor which is marked with a small triangle.
  • The magnet and sensor also have to be aligned/centered thickness-wise on as similar a level as possible.
  • In case of a weak or a bad signal, change the location of the entry sensor or strengthen the signal with a smart plug.


  • Clean the surface before mounting.
  • The entry sensor (a) should be mounted to the frame using the double stick tape, already applied on the back of the sensor and magnet. Press firmly to secure sensor.
  • The magnet (b) should be mounted on the door or window no further than 5mm away from the arrow on the sensor.
  • There are many ways to mount the sensor and magnet, as windows and doors vary greatly. The most important consideration is for the magnet to be placed as near to the point on the sensor indicated by the grey arrow.
  • The sensor and magnet may be placed on separate three dimensional planes, though this does affect the maximum distance allowed. The magnet may also be placed either facing the side of the sensor or sitting parallel to it.

Reset your device

Resetting is needed if you want to connect your entry sensor to another gateway or if you need to perform a factory reset to eliminate abnormal behavior.

The reset button is marked with the small ring on the front of the sensor.


  1. Press and hold down the reset button for approximately 8-10 seconds.
  2. While you are holding the button down, the LED first flashes once, then two times in a row, and finally numerous times in a row.
  3. Release the button while the LED is flashing numerous times in a row. 
  4. After you release the button, the LED shows one long flash, and the reset is completed.


  • ACTIVATION MODE - A single green flash means that the sensor and the magnet are moving either away from or towards each other.
  • SEARCHING GATEWAY MODE - Red flashes every second for a longer period, means that the device is searching for a  gateway.
  • LOST CONNECTION MODE - When the red LED flashes 3 times, it means that the device has failed to connect to a gateway.
  • LOW-BATTERY MODE - Two consecutive red LED flashes every 60 seconds, means that the battery should be replaced.

Fault finding

  • If the entry sensor does not work when the window or door is parted, the probable cause is a faulty battery. Replace the batteries if they are worn out.
  • In case of a bad or weak signal, change the location of the entry sensor. Otherwise you can relocate your gateway or strengthen the signal with a smart plug.
  • If the search for a gateway has timed out, a short press on the button will restart it.

Battery replacement

  1. Open the casing of the device by pushing the fastening on top of the device to remove the front panel from the back cover.
  2. Replace the batteries respecting the polarities. The entry sensor uses 2xAAA batteries.
  3. Close the casing.
  4. Test the entry sensor.
