Systemd services to announce system startup and shutdown via ntfy.sh notifications.
To install, copy the service files into /etc/systemd/system/.
Create a topic on ntfy.sh (for custom instance see customization below) and enable the services using yourTopicName:
systemctl enable ntfy-startup@yourTopicName.service
systemctl enable ntfy-shutdown@yourTopicName.serviceTo just test if it works, use start instead of enable.
Aside from directly editing the service files, they can be customized using override configurations (conf file in /etc/systemd/system/ntfy-startup@yourTopicName.service.d/ or using systemctl edit ntfy-startup@yourTopicName.service).
The following environment variables are intended to be customizable:
| Variable name | Description | Default value | supported by startup | supported by shutdown |
|---|---|---|---|---|
NTFY_URL |
Base URL to self hosted instance. | https://ntfy.sh |
✅️ | ✅️ |
NTFY_TAGS |
