LoRa Sensors Connectivity Troubleshooting
If your LoRaWAN sensors aren't transmitting data, follow these steps to resolve the issue:
Before getting started
Please make sure to have your tools ready!
A small Phillips head screwdriver
A new/replacement battery
1. Reboot/Reset Your Sensor
The first thing that we should do any time there is a sensor that is either not connecting, giving incorrect reading, or working improperly we should reboot the device. to do so:
Carefully remove the battery from the device (see these instructions on how to replace the battery)
Wait 60 seconds
While waiting, please make sure that you inspect your device for any rust, corrosion, or physical damage Example:
Replace the battery back into the device after waiting 60 seconds(and replace the screw if necessary)
Reset the Sensor (models listed):
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.
2. Replace Your Sensor's Battery
*Please note* Poor connection has the potential to cause above-average battery drain, your battery may be fresh but it will still need to be replaced before continuing with additional troubleshooting steps
3. Verify Gateway Connection
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.
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.
Do not reactivate sensors until the gateway is online and sending readings.
4. Place and Reset Sensor
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.
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.
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.
4. 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.
