Troubleshooting: WB1000 - M5 Link Icon is Red

If the link icon is red, it means your M5 is not properly connected to your station. Please follow the bellow steps to troubleshoot the issue:

Step 1: Frequency and LED Check

• Ensure the M5 Gateway's frequency matches your weather station. See documentation on "Change frequency" for guidance.
• Observe the LED on the weather station to ensure it flashes every 16 seconds (see "Reset Button and LED Indicator").

Step 2: Battery Check and Replacement

• If the LED is not flashing every 16 seconds, replace the batteries in the weather station. Confirm the batteries are correctly oriented and the polarity is correct.

Step 3: Troubleshoot Communication Issues

• If replacing the batteries does not resolve the issue, consider potential temporary loss of communication, which could be due to interference or location factors.
• Power down and then power up the M5 Gateway.
• Note: In cold weather environments, use lithium non-rechargeable batteries for optimal performance.

Step 4: Re-Establish Connection

• With the weather station and M5 Gateway approximately 3 meters (10 feet) apart, remove the batteries from the weather station, wait 10 seconds, then reinstall them.
• Verify that the M5 Gateway now displays all observations from the weather station.

Step 5: Optimise Placement

• Place the M5 Gateway at the desired location and ensure it continues to receive data.
• Avoid placing the power adapter or the M5 gateway near devices that generate electrical noise such as TVs, monitors, computers, or transmitting devices.

Step 6: Adjust Proximity and Positioning

• If issues persist, adjust the distance between the weather station and the M5 Gateway:
  • Minimum distance: 1.5 meters (5 feet)
  • Maximum distance: 50 meters (164 feet), depending on whether you are using the internal or external LoRa antenna.
• Ensure no metal barriers or obstacles interfere with the line of sight and communication.

Step 7: Use External LoRa Antenna

• Consider switching to the external LoRa antenna provided with the M5. Note that installing this antenna requires opening the M5 unit.
• For visual instructions, refer to this video guide.

By following these steps methodically, you should be able to diagnose and resolve the red link icon issue with your M5 Weather Station. If problems continue after these checks, it may be necessary to consult with customer support for further assistance.
