Downlinks

Restart Device

The device supports downlink commands to restart the device, the application port is 50 by default.

Channel
Type
Description

ff

0a (Reboot)

1 Byte, Uint8 01 => Reboot the device

ff

0b (Restart)

1 Byte, Uint8

01 => Restart the LoRaWAN Interface.

Example

To restart the LoRaWAN interface you send the following HEX payload over fPort 50.

ff0b01
// ff -> channel -> ff
// 0b -> type -> Restart LoRaWAN Interface
// 01 -> action -> Restart

Device Configuration

The device supports downlink commands to configure the working of the device, and control the relay outputs.

The application port for sending the device configuration is fPort 50

Channel
Type
Description

ff

CT1 (Primary CT)

2 Bytes, Uint 16

Set the primary current transformer ratio (value between 0-9999).

CT2 (Secondary CT)

1 Byte, Uint 8

Set the secondary current transformer ratio (value between 0-5).

VT1 (Primary VT)

4 Bytes, Uint 32

Set the primary voltage transformer ratio (value between 30-500000).

VT2 (Secondary VT)

2 Byte, Uint 16

Set the secondary voltage transformer ratio (value between 30-500).

CT Inverse

Set the Current Transformers as inverse. (if the current transformers are installed in the wrong direction)

Example

To set the channel 1 output to on and disable the button function override for channel 1 you send the following HEX payload over fPort 50.

xxxxxxxx
// xx
// xx
// xx

Device Parameter Reading

The device supports downlink commands to read its readable parameters, the application port is 100 by default.

Channel
Type
Description

FF

CC (Read Parameter)

Maximum of 10 parameter types (only readable parameters)

Example

To read the model, serial number and battery percentage you send the following HEX payload over fPort 100.

xxxxxxxx
// xx
// xx
// xx

Read data logger

The device supports reading the contents of the datalogger using a downlink on fPort 12. The downlink will result in a series of uplinks containing the datalogger entries.

Example

Restart the LoRaWAN Interface.

ff0b01

Channel

Type

Value

ff

0C (Read data logger)

01 => Read

Periodic Transmissions

Device Data

The device allows for configuration of the registers that should be sent and in which interval by using a downlink message.

There are 5 “slots” available for this configuration which are represented by the fPorts 1-5 Each slot can take 10 registers, this means that a total of 50 registers can be send over the LoRaWAN interface.

The lower slots have a higher priority. The device comes with a “Default Uplink” configured on fPort 1. All downlink commands should be send to the Application port, which the configuration is for

If a configuration downlink is send to fPort 1, the default uplink is overwritten!

Uplink Configuration

YOBIIQ advises you to use the official Device Codec to configure the downlinks, it allows you to configure downlinks by using the names of the registers you want to include.

To configure the periodic uplinks by the device you can send a downlink to fPort 1 to 5. Each fPort can hold 10 register id’s.

If confirmed mode is off, the device will send a package 1 time; if confirmed mode is on, the device will resend a package maximum of 3 times if it does not get an acknowledgement from the network.

Channel
Type
Description

ff

14 (Interval)

1 Byte, Uint 8

Set the interval of the uplink, in minutes.

15 (Confirmed)

1 Byte, Uint 8

Confirmed mode off => 0 or confirmed mode on => 1

16 (Active)

1 Byte, Uint 8

Set the status of the fPort : inactive => 0 or active => 1

17 (Registers)

Maximum of 10 registers to include in the uplink.

Example

To configure the device to sample the consumption every 5 minutes, transmit every 4 hours with a treshold of 10 without including internal sensors you send the following HEX payload over fPort 100.

xxxxxxxx
// xx
// xx
// xx
