Topic: ChirpStack Integration Events Not Forwarded to MQTT or HTTP

Description

I am experiencing an issue with the SEEED U868 LoRaWAN Gateway and the SenseCAP 2120 Weather Station when integrating with ChirpStack. The device is configured correctly, and uplink events are visible in the ChirpStack application logs. However, these events are not being forwarded to the configured integrations (MQTT broker or HTTP endpoint).

Here are the details of the setup:

  1. Gateway Model: SEEED U868 LoRaWAN Gateway

  2. Connected Device: SenseCAP 2120 Weather Station

  3. ChirpStack Integration Configuration:

    • MQTT: Verified Mosquitto broker working locally on tcp://localhost:1883.
    • HTTP: Verified the local HTTP server endpoint is reachable and functional.

  4. Problem Observed:

    • Device uplink events (UP) are visible in ChirpStack’s Device Data tab.
    • These events do not trigger the configured MQTT or HTTP integrations.
    • No messages are observed in the Mosquitto logs or the HTTP server.

  5. Steps Taken to Troubleshoot:

    • Verified the MQTT broker (mosquitto_sub) and HTTP server using test payloads.
    • Confirmed that ChirpStack is configured to forward events to the MQTT and HTTP integrations.
    • Checked the LoRaWAN device and gateway configuration for compatibility with ChirpStack.
    • Enabled debug logging on ChirpStack to trace integration issues.

  6. Expected Behavior:

    • Uplink events generated by the SenseCAP 2120 Weather Station should be forwarded to the MQTT broker and HTTP endpoint as configured in ChirpStack.

  7. Actual Behavior:

    • No MQTT messages are published to the broker.
    • No HTTP POST requests are sent to the integration endpoint.

Please advise on how to resolve this issue or let me know if additional debugging steps or logs are required. Thank you!
