LoRa Sensors Connectivity Troubleshooting

If your LoRaWAN sensors aren't transmitting data, follow these steps to resolve the issue:

1. Verify Gateway Connection

  1. Check Gateway Status:

    • Open the Jolt app and go to Sensors.

    • Ensure the gateway shows a recent reading (less than 5 minutes old). If it's offline, refer to the Gateway Troubleshooting guide.

  2. Important: If the gateway is offline, sensor batteries may drain quickly. To prevent battery drain, put sensors into sleep mode:

    • JRB 301: Remove the battery.

    • JRB 004s (Firmware < 2.4): Remove the battery. (Firmware ≥ 2.4 preserves battery life even when disconnected.)

    • L01, LRTD01: Remove batteries.

    • DLHT65, DLH65N: Press the ACT button 5 times rapidly until a long red light indicates sleep mode.

  3. Do not reactivate sensors until the gateway is online and sending readings.

2. Place and Reset Sensor

  1. Optimize Sensor Placement:

    • Position the sensor 10-15 feet from the gateway to establish a strong initial connection.

    • If the sensor connects nearby but loses connection at a distance, there may be interference. Refer to Improving Sensor Signal Strength & Connectivity for solutions.

  2. Reset the Sensor:

    • JRB 004: Shake the sensor back and forth 3 times to trigger it.

    • JRB 301: Open the sensor enclosure and reseat the battery (does not support shaking).

    • DLHT65, DLH65N: Hold the ACT button for 5 seconds until the sensor blinks green 5 times, then red, and finally shows a long green light. No long green light means the sensor couldn't connect. Verify the gateway is online.

  3. Verify Sensor Connection:

    • After resetting, check the sensor details page in the Jolt app for a recent reading.

    • If the sensor doesn’t show a reading within 20 minutes, reset it again and check in an hour. Sensors can sometimes take a few hours to send their first reading.

3. Contact Support

If the sensor still isn’t transmitting data after following these steps:

  • Contact Jolt Support for further assistance. Provide details about the sensor model, gateway status, and any troubleshooting steps you’ve already taken.
