The LibreNMS importer can be used to import devices from Libre to Unimus using the LibreNMS API.
If the importer is configured to run periodically on a schedule, this will effectively sync devices in your Libre instance to Unimus.

The importer supports syncing devices based on Device Groups. You have many options for Device Group membership filtering in Libre - so you can choose which devices get put into which groups.
You can therefore setup appropriate devices to automatically belong to specific groups in Libre, and import only desired devices into Unimus from these groups.

How to configure the importer

1) Provide the full Libre server URL in the "LibreNMS server url" field.
For example: "https://10.2.0.111:2324/".

2) Provide username and password to access Libre.

3) Configure Device Groups, to import devices from, one per line.

4) Optionally, you can also schedule the importer.
You simply need to select an existing (or use the default) schedule.
With this configuration, Unimus will sync against Libre periodically.
