Network Server

Based on the ChirpStack open source project, Semtech’s free Network Server is ready for you. When using the Semtech Network Server, you can connect up to 10 devices and three gateways in a hosted LoRaWAN® environment to build and test your IoT solutions before going into production.

In addition, by using this network server, you can validate the functionality of your solutions, from the end node application all the way up to the cloud. You can also benchmark different solutions in a hosted environment—totally free of charge.

If you have already registered for the LoRa® Developer Portal, your current login will allow you to gain access to the Network Server as well. If you do not have an account, click here to register.

New and Improved! Updates Coming to the Semtech Network Server

With its new integration with the open source Device Repository from The Things Network, the Semtech Network Server will soon provide out-of-the-box support for many LoRaWAN® end devices, including payload decoders. The only thing that you’ll have to do is select your device from the list, and you are good to go!

We are also adding a dashboard, so you can immediately visualize your sensor data within the Semtech Network Server and track device metrics. Furthermore, the Semtech Network Server offers many integrations, including MQTT, HTTP callbacks, and IFTTT.

Finally, did you know that you can also integrate the Semtech Network Server within your Node-RED flows?


The new Semtech Network Server brings many new features and enhancements. However, some of these changes might break your existing integration. To prepare for this update:

  • Upgrade your ChirpStack Gateway Bridge to version v3.14.0 or later; all configuration stays the same.
  • We will migrate all your data and your devices will continue working. Rest assured, you won’t even need to reactivate them.
  • If you integrated the Semtech Network Server into your own application, review the ChirpStack v4 Breaking Changes documentation for a complete listing of potential compatibility issues.
