+1 for ntfy it’s great. I’m using their free servers though and it just routes my curl’d alerts to the phone app. Will have to look into self hosting it that sounds neat, love that you repurposed an old phone for that.

I use my husband complaining that something stopped working and then me realizing it has been broken for days
Why you gotta call me out like this?
ntfy
I like ntfy.sh a lot. Sending a notification is a simple cURL request, and they have mobile apps. Also I gotta mention healthchecks.io for any cron job or uptime monitoring, which has ntfy.sh support built in.
Exactly what I use. Both are very low footprint, so they sit on an old raspberry pi, with the rest of the services on the n100. Works great for me.

Is "my users" a valid answer? xD
Yes. My stuff is only for me, so the only way I find out something isn't working is when I go to use it. But that almost never happens.
The only actual notifications I get is for updates.
E-mails and "I can tell by the way that it is"
I use pushover for everything alerting, from home assistant to nagios.
A 1 time payment and you get 10,000 alerts a month
Just be aware that if you're using the Android client, your phone/tablet will probably at some point put it into deep sleep which will prevent it from displaying notifications. You can (and should) change this in the app settings.
I'm old and don't have any identifiable infos in my alerts so I use plain mail messages. If for some reason mail wasn't a good option, I'd use ntfy
I am running an alertmanager instance which sends the alarms to telegram using a bot account.
Same, but I send them to my gotify instance.
Mostly Zabbix and my own email server. Way I figure if there's something broken enough to take out the email internally I'm probably already dealing with a broader issue.
I use Munin for monitoring and XMPP for alerts via go-sendxmpp. That way I just configure munin like this:
contact.admin.command go-sendxmpp -u [bot_username] --password [bot_password] [contact]
And that sends me messages to my main XMPP account whenever my servers breach a limit.
Thanks for the link to go-sendxmpp. It's nice to have an xmpp-native way to send notifications
Gotify. Fast. Easy. Private. The messages live on my server.
Also, there is a Gotify app in F-droid to get notifications on the go.
for my homelab i went with free tier of hetrixtools. it monitors uptime from different locations and has a number of alert options (email, webhook, etc.). free tier was enough for my small needs. as a bonus it also alerts for certificates nearing expiry, smtp monitor, heartbeat. pretty good for hobbyists.
I have signal-cli set up on my home assistant and use that for notifications from home.assistant as well as uptime kuma, etc.
This is a neat idea. Thanks.
I host a matrix chat server with signal bridge and hit the matrix API to send messages. Basically the same thing but more hops. I might set that up too.
I'm using matrix directly for server notifications. I didn't realize it could integrate with signal. What's the use case there, either for server notifications or in general?

I send my grafana alerts via Matrix (selfhosted) and Email (paid service), so either way it reaches me. Has worked out well enough so far
monit + email
For me it's the constant notifications I get from DAVx5 telling me that it can't connect to my Nextcloud server.
All of my alerts go to Apprise, which sends it to Home Assistant. Home assistant allows me to either have silent notifications in the app I can look at later, or send as a push notification to my phone.
I don't presently, but back when I was working on a large codebase and needing to know when a painfully long compile finished, I used an XMPP client and server.
I use pushover mostly. It'll let me know when disks are full, certs need renewing.
Home assistant for home stuff. Sauna is heating, sauna reached temperature, boiler took a break because electricity is expensive, washing machine is done.
Was using ntfy.sh until it was AI slopped. Now I'm on apprise. But ntfy was superior.
What happened to ntfy? Care to elaborate a bit?
This release : https://github.com/binwiederhier/ntfy/releases/tag/v2.18.0
This is the biggest release I've ever done on the server. It's 14,997 added lines of code, and 10,202 lines removed, all from one pull request that adds PostgreSQL support.
The code was written by Cursor and Claude, but reviewed and heavily tested over 2-3 weeks by me.

I use smtp_to_telegram
I don't have many alerts setup, but I use Mattermost anyway and I send alerts into a Mattermost channel. Sonarr and Radarr report when a download is complete. Jellyfdash reports when someone outside my home starts streaming something over Jellyfin.
I created a slack workspace. Alerts sent via alert manager to a channel. Also has channels for ci runners, home assistant etc.
zabbix with ntfy for short term alerts and a telegram bot for long-term alerts.
My current setup is Uptime Kuma sending notifications via Ntfy.
I need to resolve the issue of what to do when the internet is down (and thus Ntfy cannot be reached), but it has so far done everything I want it to do. It also means I get push notifications on all the devices I care to receive them on.

Depends...
If someone's just arrived home, the freezer door's open, etc, then I'm using Home Assistant to speak / flash a light / etc.
If a device fails, then Uptime Kuma sends via to ntfy & gotify (I'm trying both atm to decide on one)
If it's something I've (not) done, then my partner tells me (arms folded, stern look)
Uptime Kuma
I’m using an Uptime Kuma container which can be configured to alert through just about anything you like.
The only notifications I use are for my cameras through frigate so I just use home assistant to send push notifications when someone walks up to my house.
Peekaping hooked into home assistant for notifications.
