    ntfy.sh Integration#

    Pro Plan and Above#

    ntfy is a free, no-signup push service. Subscribe a phone or browser to a unique topic and LemWatch will push alerts to it.

    Setup#

  1. Install the ntfy app from the App Store / Play Store, or open ntfy.sh in any browser.
  2. Subscribe to a unique topic like lemwatch-acme-9f2c — anything unguessable, because anyone who knows the topic can read messages on the public server.
  3. In LemWatch: Settings → Notifications → ntfy URL → paste https://ntfy.sh/lemwatch-acme-9f2c (or your self-hosted equivalent).
  4. Click Send test to verify.

    5. Self-hosted ntfy#

    Replace ntfy.sh with your own host (e.g. https://ntfy.your-domain.com/<topic>). The endpoint must be HTTPS; LemWatch blocks private/loopback IPs.

    Message format#

    ntfy receives a plain-text title + body with severity emoji and a link to the LemWatch dashboard. The mobile app shows it as a native push notification with sound.

    Tips#

  5. Pick a long random topic name — there is no authentication on the public ntfy.sh server.
  6. Use a self-hosted ntfy server (with auth) if alerts contain sensitive site names.
