Connect LoRaWAN sensors

LoRaWAN sensors run on batteries for years and reach far through walls. Your network server — The Things Stack, ChirpStack or the server built into a Milesight gateway — forwards each uplink to FreeMaint over HTTP. For the Milesight CT101 and EM300-TH, FreeMaint decodes the payload itself.

Choose your source

The Things Stack

1. In Connected devices → Integrations, click Connect a device, choose The Things Stack (LoRaWAN) and create the connection.
2. In The Things Stack console, open your application → Integrations → Webhooks → Add webhook → Custom webhook.
3. Choose the JSON format and paste the base URL shown by FreeMaint.
4. Under Additional headers, add the header shown by FreeMaint (name and value).
5. Tick Uplink message and leave its path empty. Do not tick Request authentication: it would replace the FreeMaint header.

ChirpStack

1. Create the connection in FreeMaint, choosing ChirpStack (LoRaWAN).
2. In ChirpStack, open your application → Integrations → HTTP → Add.
3. Keep the JSON payload encoding and paste the event endpoint URL shown by FreeMaint.
4. Under Headers, add the header shown by FreeMaint (name and value).

Milesight gateway

1. Create the connection in FreeMaint, choosing Milesight gateway.
2. In the gateway's web interface, open Network Server → Applications → your application.
3. Add an HTTP(S) data transmission and paste the uplink data URL shown by FreeMaint.
4. Add the HTTP header shown by FreeMaint (name and value).
5. Do not set a payload codec on the gateway: FreeMaint needs the full uplink to decode certified sensors.
