5.Product description #

The SQUID is a sensor equipped with 12 current measurement clamps which send measured current values by means of a wireless LoRaWAN link.
The products sends the consumption index of the 12 clamps in Ah (in orange in the graph bellow) at configurable intervals.
The SQUID is powered by 5V DC by means of an external power supply.

6.Product installation #

Mounting and disassembly

This equipment must be installed on a DIN 35mm rail mounted horizontally on the electrical panel.
Make sure to snap the box properly into the DIN rail.
Make provision for the location of 5 modules to install the product on the electrical panel. To disassemble, use a flat head screwdriver to loosen the black clip located under the product.

Prerequisite

A 5V DC-2A power supply must be used to power the SQUID. The wiring of the Safety Extra Low Voltage circuits must be maintained and kept separated from circuits carrying hazardous voltages.

Connection of the measurement

Connect the measurement probes to the 12 connectors on the top and bottom of the equipment. Current must not exceed the maximum specification of the clamp.

7.Radio communications #

LoRaWAN™ Configuration

The SQUID periodically transmits current measurements performed on his 12 measurement clamps in the form of consumption indexes (Ah) via a LoRaWAN™ radio link
To be able to configure a SQUID on the LoRaWAN™ network, you must use the following codes:

DevEUI : This is a factory programmed identifier which makes each object unique and is indicated on the label of each product. E.g. 70B3D54750120168
As well as the two codes AppEUI and AppKey provided with your order.

Network connection process

Our products try to connect to the network when they start.
If it does not work, they will retry every 24 hours until it works.

Periodique network reconnection

Our products restart a network connection procedure every 7 days.
These reconnections improve security.
Indeed, reconnection to the network renews the encryption keys.

Payload descriptions

The SQUID-LoRaWAN transmits its data in a raw format on different public and private LoRaWAN™ networks.
The section below shows you how to decode the frames (PayLoad) sent by the SQUID.
