Square Presence for LoRaWAN: quick start

From the opened box to a working sensor on one page. The full manual has the details, the settings and the troubleshooting.

Revision A · October 2026 · Sensative AB

Full manual Product page Product sheet (PDF)

Square Presence detects whether people are in a room, including somebody sitting still, and reports it over LoRaWAN together with temperature, humidity and light.

In the box

  • Square Presence, with the adhesive already on the back

The Square screw mounting kit is sold separately.

You need

  • A LoRaWAN gateway, online and in range, added to your account on a LoRaWAN network server
  • The sensor’s DevEUI and AppKey, from the delivery information. The JoinEUI for all Square sensors is 70B3D52C0001D4C3
  • A phone with NFC. Android is recommended; an iPhone needs an NFC reading app
  • A payload decoder for Sensative VSM sensors (built into Yggio)
  • Optional: the Hugin NFC app (Android phone with NFC and GPS), an Yggio user account, and the sensor registered in Yggio with your organisation as its owner

From box to ready

1

Register the sensor in the network server

Add a new end device: activation OTAA, MAC version 1.0.4, regional parameters RP002-1.0.3, and the frequency plan for your region. Enter the DevEUI, AppKey and JoinEUI exactly, and set up decoding of the messages.

Done when: the device is listed in the network server, waiting for its first join.
2

Join the network with NFC

NFC on, phone case off. Lay the phone flat over the lower left corner of the front of Square Presence and keep it still for about 5 seconds: that starts the join.

Done when: the network server shows the join, usually within two minutes.
3

Choose the place and check the signal

On a wall, typically at 1.5 to 1.8 m, facing the people, so that they are inside the lobe of ±40° and up to 4 m, with nothing in between. Not in sunlight, near radiators, in ventilation airflow or next to a door or window, and not pointing at windows, TVs or radiators. Indoors only (IP30). Check the signal there.

A room seen from above: Square Presence on a wall, its lobe of ±40° and up to 4 m covering the desks; sun, a radiator, ventilation airflow, a door and a TV crossed out
Seen from above: facing the people, away from heat, cold and airflow.
Done when: the link carries at least SF9. As a rule of thumb, SNR above −5 dB and RSSI above −115 dBm.
4

Mount

Adhesive: the surface must be clean and dry. Peel the film off and press the sensor firmly in place, front facing the people. Or screw the two adhesive plates of the Square screw mounting kit to the wall and press the sensor onto them.

Cover neither hole in the front. Seen face up, the left hole is the infrared sensor and needs a clear view; the right hole is the air opening.
5

Test

Walk into the sensor’s view, sit still for a few minutes, then leave the room.

Done when: occupied arrives when you come in, and free after you leave, at the latest after one hour without movement (the default Quiet Release Time).
