The ntfy integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] allows publishing push notifications on ntfy.sh or other ntfy services.

About ntfy

ntfy is a simple HTTP-based pub-sub notification service that allows you to send notifications to phones or desktops. The official ntfy service also provides additional features, such as notifications via email or phone calls using text-to-speech to read messages aloud. Since ntfy is 100% open-source, you can choose to use alternative public ntfy services or even host your own instance.

How you can use this integration

The ntfy integration can be used to send push notifications from automations and scripts in real-time to your mobile devices and desktops.

Prerequisites

  1. Service URL

    To set up the ntfy integration, you need the URL of the ntfy service you wish to use.

    • Use https://ntfy.sh for the official ntfy service.
    • Provide the URL of an alternative public ntfy service or your self-hosted instance (for example, https://your-ntfy-instance.com).

  2. Authentication (optional)

    Depending on whether the server is configured to support access control, some topics may be read/write protected so that only users with the correct credentials can subscribe or publish to them.

    The ntfy integration uses access token authentication to access protected topics. When you provide your ntfy username and password, Home Assistant automatically generates and uses an access token for authentication.

  3. Adding a topic

    To set up topics for notifications, select the three-dot menu next to the entry of the previously configured ntfy service, then click Add topic.

    You can now choose one of the following options:

    • Select Enter topic to add a new topic. Use an existing topic name by retrieving it from the ntfy app or the ntfy service’s website. Simply copy and paste the topic name into the configuration.
    • Select Generate topic name to allow the integration to generate a random topic name automatically.

    Repeat these steps for each topic you want to add.

Note

Topics may not be password-protected, so choose a name that’s not easy to guess. If you are sending sensitive information, consider reserving the topic and restricting access to it.

To publish notifications, you can use the notify.send_message actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more].

Known limitations

ntfy imposes various rate and usage limits. The official ntfy.sh service allows up to 60 messages in a burst, with a replenishment rate of one message every 5 seconds (i.e., the full 60-message capacity refills in 5 minutes).

Additional usage limits depend on your account tier. To view your current limits, go to Account → Usage.

Limits may vary when using other ntfy services. If you’re using a self-hosted instance, you can configure higher limits or disable them entirely.

Troubleshooting

The ntfy integration relies on an active internet connection to communicate with the ntfy service. If you encounter issues, verify that your network connection is stable and the ntfy service is reachable. Additionally, the ntfy service itself may experience downtime, whether unexpected or due to scheduled maintenance.

In any case, when reporting an issue, please enable debug logging, restart the integration, and as soon as the issue reoccurs, stop the debug logging again (download of debug log file will start automatically). Further, if still possible, please also download the diagnostics data. If you have collected the debug log and the diagnostics data, provide them with the issue report.
