Accessing the FLOW LoRaWAN Decoder

The FLOW decoder interprets uplink messages sent by FLOW CORE and FLOW PRO thermostatic heads over the LoRaWAN network.

Accessing the Decoder

1. Open the Nexelec Decoders GitHub repository.
2. Select the A3 - FLOW CORE FLOW PRO folder.
3. Open the decoderFlow.js file.
4. Click Raw to display only the decoder source code.
5. Copy the code and add it to the payload decoder section of your LoRaWAN platform.

You can also access the FLOW decoder folder directly.

The repository is public, so you do not need a GitHub account to view it.

Downloading the Decoder

To download the complete repository:

1. On the repository’s main page, click the green Code button.
2. Select Download ZIP.
3. Extract the downloaded ZIP file.
4. Open the A3 - FLOW CORE FLOW PRO folder.
5. Locate the decoderFlow.js file.

Checking the Decoder

After adding the decoder to your LoRaWAN platform:

1. Send or select an uplink message received from a FLOW device.
2. Check that the payload is decoded without errors.
3. Confirm that the decoded values are consistent with the device’s current status.

This file is intended only for decoding FLOW uplink messages. It does not generate downlink commands.

Troubleshooting

If you need assistance, please provide:

• the model being used: FLOW CORE or FLOW PRO;
• the firmware version, if available;
• the name of the LoRaWAN platform;
• the complete payload in hexadecimal format;
• the decoded result or error message received.

Never share your LoRaWAN keys or any other confidential credentials.
