FAQ

How do I update the ntfy Push notification server?

See the step-by-step above. Open the NAS control panel, go to the update or system section, and install the new version. Back up important data first; NAS updates can take several minutes.

How does Firmwarely know when there's a new version?

Is this an official ntfy page?

No. Firmwarely is independent. Device and brand names belong to their manufacturers; always download firmware from the official source.
