 ====== VE.Direct LoRaWAN module manual ======
-===== 1. Introduction =====
+**NOTICE: Software Update**
-Thank you for purchasing a [[https://www.victronenergy.com/panel-systems-remote-monitoring/ve-direct-lorawan|VE.Direct LoRaWAN module]]. It allows you to connect other Victron equipment, such as your Battery Monitor (BMV); MPPT Solar Charger; or Phoenix Inverter, to the Victron Remote Management ([[https://vrm.victronenergy.com/|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. Here are some examples of the kind of information you will be able to view:
+All units with versions earlier than v1.05 have been recalled for a free software update; due to the issue that they stop transmitting after a while. How long it takes before they stop transmitting varies; and is typically between 12 and 60 days.

-===== 2. LoRaWAN radio frequencies and coverage =====
+===== Introduction =====
-The VE.Direct LoRaWAN (Long Range wide area network) module is essentially a radio transmitter which broadcasts data (in this instance information about the status of your Victron installation) to a nearby Internet of Things (IoT) gateway. The gateway should be within about 2km of your location if you live in a town, but could be as far away as 30km if you live in a rural location. This device uses infrastructure provided by 'The Things Network'. Their network of gateways is constantly expanding and you can check coverage in your area here: https://www.thethingsnetwork.org/map.

+The VE.Direct LoRaWAN (Long Range Wide Area Network) module is essentially a radio transmitter which broadcasts data (in this instance information about the status of your Victron installation) to a nearby LoRaWAN gateway. Typical range of a gateway is about 2km if you live in a town, but could be as far away as 15km if you live in a rural location. The VE.Direct LoRaWAN module uses the gateway infrastructure of 'The Things Network' community. Their network of gateways is constantly expanding and you can check coverage in your area here: https://www.thethingsnetwork.org/map.

+===== Trouble shooting the connection =====
+**Step 1:** Power: Verify that there is proper power supply connected, by checking the LED. It will always blink in some colour.
+**Step 2:** LoRaWAN connection: Verify that the LED is blinking either green or yellow. After powerup, the LED will first blink blue. Which indicates that it is establishing communication with the LoRaWAN gateway and the TTN Network. Once connected to both, 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, check that the LoRaWAN gateway is in range, and check that the region and frequencies of the Gateway and the module match. See above for details.
+**Step 3:** VE.Direct Make sure the LED is blinking green. In case its blinking yellow, check the cable to the VE.Direct device, and power to the VE.Direct device.
+**Step 4:** VRM Portal Connectivity Login to VRM, and add the module by going through the "Add installation" wizard.
+Note that adding the installation on VRM can only be done when the result of the previous steps is OK: the LoRaWAN connections needs be ok and the VE.Direct cable needs to be connected to a product & communication properly. In short, the LED needs to blink green. If there is no VE.Direct data, the module will not send any data to VRM; and then will not be possible to register the installation on VRM.
+Note that there is one situation where the LED on the VE.Direct LoRaWAN can be green; while still there is no good connection, which is with a so called "Single channel gateway". If you have such, you'll have to buy and install another type of TTN gateway.
+**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.
+{{::e7bb161bad2bc38736f3de12b8184eb4cb403641f2b030bc6aaffffc09cede6c.png?direct|}}
+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.
+**Step 7:** If all LoRaWAN gateways providing coverage have disappeared the module has no way to detect this, and will continue blinking green but its broadcasted data will never arrive in VRM. If your device is blinking green but new data is not arriving in VRM any more for a long time, reboot the device. If there is no coverage, it now will not connect and continue blinking blue. If you are using your own gateway, check that it is still operational and connected to the appropriate TTN cluster.

+No.
+**Q2: Can the firmware of the module be updated?**
+No.
+**Q3: How can I connect multiple VE.Direct devices to one LoRaWAN module?**
+You can't.
+**Q4 Can I connect both this module and something else to the VE.Direct port at the same time?**
+No you can't.
+**Q5 Can the module be used to remotely switch the load output of an MPPT?**
+No.
+**Q6 Can the module be used to remotely update firmware of the BMV, MPPT, or Inverter?**
+No.
+**Q7 Can the module be used to remotely change the configuration of the BMV, MPPT or Inverter?**
+No.
+**Q8 Can the module be used to remotely perform any other action?**
+No.
+**Q9 Is a GX Device like a Color Control GX or Venus GX required?**
+No, a GX device is not required, the data from the VE.Direct device will be sent straight to the VRM Portal from the dongle via the LoRaWan network.
+**Q10 The Peak Power Pack has a VE.Direct port, will the device work with that?**
+No.
+**Q11 I connected the module to a BMV, and then later connected it to an MPPT - but I can't see the new data …why not?**
+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.
+**Q13 Can the unit be used with another network than TTN?**
+Quite regularly we get requests to be able to use another network, ie. another one than TTN. Because TTN is not popular in a certain area, or because there already is another strong network, like TTI (The Things Industries), and so forth. Unfortunately that is not possible. To support another network, two things need doing:
-===== 6. FAQ =====
+  - Change the parameters in the VE.Direct LoRaWAN module - which is currently not possible as there is no user interface nor communications port and or protocol to change its settings.
+  - Connect our VRM back-end to the other network. For which there is no standard API, and therefore requires Victron development resources.
-//Will the module store data and send it out later when the gateway is in range?//
+The -unfortunate- conclusion is that the VE.Direct LoRaWAN module can only be used with the TTN network, and that we cannot help with with or support other networks. End of 2020 we launched another product, which uses the cellular LTE-M networks, and is a good alternative. See for more information: https://www.victronenergy.com/panel-systems-remote-monitoring/globallink-520

+**Q14 How about the TTN new v3 infrastructure?**
-===== DISQUS =====
+The Things Network (TTN) has rolled out a new version of their infrastructure called V3. We migrated to this new V3 version of TTN in September 2021. For most users no action will be required, as
-~~DISQUS~~
+the VE.Direct LoRaWAN modules was automatically rebooted and reconnected to VRM via the new V3 version of TTN when we rolled out this update.
+Note: If you are running your own gateway, please make sure you update it to work with the latest version of TTN and connect it to the appropriate cluster for your region, as they are taking their old infrastructure offline in December 2021 and all gateways still using this old version will cease to work. If you have an TTN account you will already have received an email about this change. Some users running their own gateways reported some problems with connectivity which was resolved by power cycling their gateways and VE.Direct LoRaWAN modules.
