12. Troubleshooting
Step 1: Check the device has power.
The LED on the device should be blinking in some colour. If it is not blinking, check if the power cable is connected correctly and supplies sufficient power. If you're using the included cable, be sure to also check its inline fuse which may be blown if the power pins were accidentally reversed.
Step 2: Check for cellular (LTE-M) coverage.
Verify that the LED is blinking either green or yellow. After power-up, the LED will first blink blue, indicating that it is establishing communication with the LTE-M network and VRM. Once connected, it will start blinking green (when there is a VE.Direct device) or yellow (when there is no VE.Direct device). In case it keeps blinking blue the unit will keep trying to establish a connection until there is a timeout (+/- 15 min) and then automatically reboot the device.
Note
You can check the signal strength in VRM on the advanced page where you can activate the RSSI graph. The signal RSSI should be between -50dB (best connection) and -100dB (bad connection). Below -100dB the connection will no longer work. You can also find the latest RSSI in the device list.
Check and make sure there is coverage in your country (https://1nce.com/en-eu/1nce-connect/our-coverage). If there should be coverage, but you have no signal, you can consider purchasing an external antenna.
Step 3: Check the connected VE.Direct devices.
Make sure the LED is blinking green or geen & yellow which indicates that only one VE.Direct device is connected. In case it's only blinking yellow, check the cable to the VE.Direct device, and power to the VE.Direct device.
Step 4: Find the device in the VRM portal
Login to VRM, and add the module by going through the "Add installation" wizard. Only after the module has made an active connection to the cellular network it is available in VRM.
