ntfy, self-hosted offsite on an old phone, it takes around 300mA, ie.less than a watt.
ntfy app on my phone.
Wireguard between them.

I use my husband complaining that something stopped working and then me realizing it has been broken for days

ntfy

Is "my users" a valid answer? xD

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.

I use pushover for everything alerting, from home assistant to nagios.

A 1 time payment and you get 10,000 alerts a month

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

Pushover for notifications. Paid a very small amount a decade ago. Works reliably ever since. And for monitoring I'm using Zabbix.

Gotify, super easy to setup, very basic but has everything I need.

I am running an alertmanager instance which sends the alarms to telegram using a bot account.

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.

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.

I personally chose ntfy over gotify and use it everywhere

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.

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

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 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.

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.

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.

monit + email

Uptime Kuma

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)

I created a slack workspace. Alerts sent via alert manager to a channel. Also has channels for ci runners, home assistant etc.

I use smtp_to_telegram

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.

Was using ntfy.sh until it was AI slopped. Now I'm on apprise. But ntfy was superior.

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.

For the urgent notifications that require immediate action I use apprise -> Pager duty (free tier) because it can overwrite the DnD settings on my phone and wake me up if im asleep. For all other notifications apprise -> matrix.

The only thing I rely on from day to day is my nextcloud instance, and my phone gets blown up by failed webdav synchronisation alerts when that fails...

I use AlertManager and the push notifications available on Home Assistant companion app.

The push notifications from home assistant do me fine. AlertManager webhook to home assistant and a small automation to send the push.

Could use matrix but this has been perfectly fine for now.

healthchecks.io and matrix.

I’m using an Uptime Kuma container which can be configured to alert through just about anything you like.

MQTT and a vibecoded flutter app that subscribes to topics and will publish acks so it mutes alerts on other devices in my networks. Nothing I could find on the appstore would stay active well enough to be trusted. This one is pretty bulletproof.

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.
