Adding the integration
Create the connection under Management → Integrations. See Managing integrations.
Use the correct DSM URL
Enter the HTTP or HTTPS URL of your Synology DSM web interface, for example http://diskstation.local:5000
or https://diskstation.local:5001. If DSM uses a self-signed certificate, add it under
Management > Tools > Certificates so Homarr can connect securely.
Secrets
| Name | Description |
|---|---|
Username | Account username for authentication. |
Password | Account password for authentication. |
Administrators group required
Two-factor authentication is not supported
First-time setup
Steps to retrieve the credentials:
- Create a dedicated DSM user with a strong password for Homarr.
- Add the user to the default Administrators group so Homarr can read `SYNO.Core.System` metrics.
- Under User Groups and Permissions, deny access to shared folders and most applications.
- Allow login to DSM only, optionally restricted by source IP address.
- Log in once with the service account in DSM to accept terms and conditions.
Storage volume selection
Health Monitoring and System Disks widgets can filter Synology storage volumes when every selected integration is a Synology DiskStation. Leave Visible storage volumes empty to show all volumes, or pick specific volumes from the list. When multiple Synology integrations are connected, volumes are labeled with the integration name.
Synology-only option
The volume filter is hidden when the widget also uses non-Synology integrations such as TrueNAS or Unraid.
Volume ordering
When no volume filter is configured, the first volume returned by DSM is not guaranteed to be volume_1.
