Free internet connection using LoRaWAN to VRM

It’s a little unfair of me to grab your attention with the ‘free internet’ connection and the new VE.Direct LoRaWAN module to the VRM, but it’s true – no data charge. However as with everything there’s always two sides to the coin – benefits to connecting products this way and some limitations. Regardless this new product might just be what you need to connect Victron products to monitor data remotely, such as battery monitors, solar charge controllers and inverters.

Typical examples

Before explaining LoRaWAN (in case you are not aware of it) it makes more sense to give you an idea of how you might connect and use the new Victron Energy module.

What is LoRaWAN?

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

No gateway in your area?

If there’s no coverage in your area it’s simple to add a gateway yourself be that to improve the coverage of the Things Network, either for your personal use or to benefit others. You can purchase your own gateway, or start building one yourself. Why not check out the From zero to LoRaWAN in a weekend guide.

Ordering

Now the first batch of modules have arrived in stock with more following immediately – check e-order or with your dealer for current stock levels and delivery.

Conclusion

If you have an application that requires a no data cost monitoring solution where hourly data notifications are suffice – then the VE.Direct LoRaWAN module may well be the answer. Free data connections can only be a good thing!
