- | Thank you for purchasing a VE.Direct LoRaWAN module. It allows you to connect other Victron equipment, such as your Battery Monitor (BMV); Solar Charger; or Phoenix Inverter, to the Victron Remote Management (VRM Portal) portal. The portal is available to use free of charge, and from it you can view the status of your installation from anywhere in the world using your desktop device or mobile phone. | + | Thank you for purchasing a VE.Direct LoRaWAN module.

**Step 5:** Check LoRaWAN signal strength On VRM, go to the Device list entry and unfold the Gateway entry. In the list you will find the RSSI and SNR parameters, whom together indicate the quality of the wireless connection. | **Step 5:** Check LoRaWAN signal strength On VRM, go to the Device list entry and unfold the Gateway entry.

+ | A higher RSSI (Received Signal Strength Indicator) indicates a better signal, where -30dB is the best possible, and -130 dB the worst: no signal it all. Everything below -75 dB is considered a bad connection and has a high risk of packet loss. The SNR is the Signal to Noise Ratio. This ranges from positive plus 10 to negative -20. Anything above 6 and below -10 is good. | ||
+ | |||
+ | If you have a bad connection try to place the antenna in a higher position or closer to the gateway. Typical range of LoRaWAN is around 2km in an urban area and up to 15km in rural areas with a good gateway. | ||
+ | |||
+ | **Step 6:** Verify completeness of data on VRM The LoRaWAN network needs to receive three messages before making all the device data available on the VRM Portal. As the LoRaWAN network is a lossy network it is possible that not all of those messages are received the first time. These messages are only sent once every 24 hours by the VE.Direct LoRAWAN device. To solve without waiting 24 hours, power cycle the module and try again. | ||

Make sure you power-cycle the LoRaWAN module by switching it off whilst connecting it to a different VE Direct device. Or wait for a minimum of 24 hours. | Make sure you power-cycle the LoRaWAN module by switching it off whilst connecting it to a different VE Direct device. Or wait for a minimum of 24 hours. | ||
+ | **Q12 Can I connect my VE.Direct device to a LoRaWan dongle and a GX device (eg Cerbo GX) at the same time?** | ||
+ | |||
+ | It is not possible to connect a VE.Direct devices with a single communications port (eg MPPT or BMV) to a GX device and the LoRaWan dongle at the same time. |
