VE.Direct LoRaWAN module manual
NOTICE: Software Update
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.
You can find your version number in the VRM portal. Go to your installation → open device list in the
left menu → unfold the gateway tab and find the firmware version.
Introduction
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.
LoRaWAN radio frequencies and coverage
warning: LoRaWAN Coverage The “The Things Network” LoRaWAN network is not a commercial
network. Public gateways are maintained by the community and coverage can not be guaranteed.
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 15km 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.
tip: Add your own gateway You can even expand the TTN IoT infrastructure to your area by
establishing a new gateway. The hardware cost would be a few hundred Euro's, and you would need a
power supply and an internet connection.

Bandwidth and frequencies
warning: Unsupported Frequencies We do not support the TTN AU923 Frequency for Australia,
only the AU915Mhz. Please make sure your gateways are on the correct frequency.
Whilst it's free to use, and long range, LoRaWAN is not high bandwidth. Therefore data is only sent
once an hour …some less important data is only sent once every 24 hours. (See below for more
information.)
Frequencies used by the LoRaWAN module differ by region and country. We stock three different
versions:
ASS030538010 - VE.Direct LoRaWAN EU863-870 module
ASS030540010 - VE.Direct LoRaWAN US902-928 module
ASS030542010 - VE.Direct LoRaWAN AU915-928 module*
The EU version can be used in most of Europe and certain countries in Africa. The US model can be
used in the Americas.
Product compatibility

Mount the LoRaWAN Module close to the device you wish to monitor2.
Connect the VE.Direct cable between devices3.
Connect the DC Power (8V - 68V, looking to the module with green connector below of the4.
module, the positive is on the left)
After a short wait the LED will blink green indicating that all is OK5.
Go to the VRM Portal to add your installation6.
Details
After power-up, the module will gather information from the VE.Direct device. Once received it
connects to the LoRaWAN network, and then sends all available data to the VRM Portal.
After this first transmission, it will send the most important data hourly:
BMV and SmartShunt Battery Monitor
Battery Voltage
Battery Current
Battery Power
State of Charge
Alarm status & reason
MPPT Solar Charger
Solar Power
Battery Voltage
Battery Current
Battery Power
Error code
Charge state (Off, Bulk, Absorption, Equalize, Float)
Phoenix VE.Direct Inverters
Battery Voltage
AC Output current
Alarm status & reason
Mode (On/Off/Eco)
Note that data may not always arrive at the VRM Portal every hour. Transmission over the air can fail -
even when your LoRaWAN device is mounted close to a gateway. This is normal and part of the
LoRaWAN concept.
LED Codes

Blinking blue Connecting to LoRaWAN. If your module keeps blinking blue, check LoRaWAN
Network coverage.
Blinking green Everything is OK and a connection has been made both to LoRaWAN and to the
VE.Direct device.

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.
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.
2020-09-30 06:30 5/7 VE.Direct LoRaWAN module manual
Victron Energy - https://www.victronenergy.com/live/
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.

https://www.victronenergy.com/live/ Printed on 2020-09-30 06:30
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:
Change the parameters in the VE.Direct LoRaWAN module - which is currently not possible as1.
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, and2.
therefore requires Victron development resources.
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'll launch
another product, which uses the cellular LTE-M networks, and is a good alternative.
