With FlowFuse, you can use Provisioning Tokens to register large numbers of devices. This will automatically register each device in the FlowFuse Editor and save you a lot of clicking.

The key advantage of the device agent is that it allows you to access the Node-RED editor from FlowFuse directly. Simply navigate to the device in the FlowFuse UI, and click on the "Open Editor" button. Once you've made your changes, within FlowFuse you can then rollout those flows to hundreds of other devices in just a few clicks.

"Fleet Mode" allows you to deploy a single Snapshot to multiple devices at once. The Device will have a "Target Snapshot", and whenever that is set, your device will automatically update.

"Developer Mode" on the other hand opens a tunnel to your device, allowing you to edit the flows on that device directly. This is useful for debugging flows, or testing new flows on live hardware, before distributing them out to the rest of our

Device Agent supports NodeJS 14 and above, and is designed to work with a wide range of devices. If you're unsure if your device is supported, please do get in touch.
