ntfy not receiving netalertx notifications

[useruser-useruser]

Hello! Lovely work on this, first off. I appreciate the hard work the developers and community have put into this.

I am trying to have notifications for specific devices going down and new devices joining my network to be sent to my smartphone using ntfy. However, the notifications never reach ntfy. Here are the steps I took. Please let me know what I am doing wrong (thank you in advance!):

1. Enable notifications in netalertx for the device in question (Notifications config > check Alert Events and Alerts Down).
2. Go to settings > core > general > loaded plugins, add ntfy. Save.
3. Go to settings > core > notification processing, double check that new_devices, down_devices, and events are showing up in Notify On. Change Alert Down After to 1 minute (for testing). Save.
4. Go to settings > publishers > ntfy publisher. Change When to run to on_notification. ntfy host url is https://ntfy.sh. Put the ntfy topic in the ntfy topic box. Change message priority to default. Save
5. Go to the smartphone. Open ntfy app. Add a subscription. It defaults to ntfy.sh, so I only need to put in the topic. I put it in exactly the same as it is typed into netalertx (I quadruple checked, then quadruple checked again). Change the notification setting to default. Save.
6. Disconnect the test device from the network. Wait 1 minute. Wait another few minutes in case netalertx hasn't picked it up right away. It says in netalertx that that device is disconnected, but nothing ever comes to ntfy on the smartphone.

I ran curl -d "test" ntfy.sh/[topic name] on the device that is hosting netalertx and the test came through to the smartphone immediately. This makes me think it's netalertx. I then, in netalertx, went to Devices > My Devices > [test device] > plugins > ntfy publisher and saw two instances when it seems it tried to send a notification to ntfy and must have failed, because the output was:

"{\"code\":40401,\"http\":404,\"error\":\"page not found\"} "

So it seems that somehow maybe netalertx isn't correctly parsing https://ntfy.sh/[topic name].

Any thoughts on this? Is there a part I'm done extremely obviously wrong but I'm too much of a noob to know what it is? I would appreciate any help at all! Thank you <3

Hi,

Thanks for the detailed write-up.

Did you specify the NTFY_TOKEN? You don't seem to mention it in your message. Also, I recommend checking the logs for any errors under Maintenance -> Logs. See https://jokob-sk.github.io/NetAlertX/DEBUG_PLUGINS/?h=troubleshooting+plugins for details.

So of course it ends up working the next morning. I think there's a delay built in that I haven't checked somewhere; it only seems to work if I'm disconnected for more than around 10 minutes. I'm going to dig deeper to find that, I'm sure it's a setting that I overlooked/ignored. I appreciate you following up though!

Glad to hear that there's progress! You can also read through the notification docs and feedback if something is not clear - or if something could be explained better: https://jokob-sk.github.io/NetAlertX/NOTIFICATIONS/?h=notif - PRs to the docs are welcome as well! :)
