Out of curiosity I've built what @luckow suggested, only with Cloudron API (notifications endpoint) -> n8n -> some magic -> ntfy.sh-app and it looks like this:
f036453c-4190-48d2-bae2-33c5e16133b5-image.png
Action gets triggered (either automatically or manually), n8n checks the cloudron api https://my.example1.com/api/v1/notifications (create a readonly access token in your profile and update the Bearer token with it) with the parameters acknowledged = false, so only unread notifications are collected.
The code-node does the following (filteredTitles because I don't care about app-updates, only actual issues, can be adjusted of course):
const notifications = items[0].json.notifications; const types = notifications.map(notification => notification.type); const titles = notifications.map(notification => notification.title); // Filter notifications to remove those with type "appUpdated" const filteredNotifications = notifications.filter(notification => notification.type != "appUpdated"); // Extract titles of the filtered notifications const filteredTitles = filteredNotifications.map(notification => notification.title); //return [{ json: { types, titles } }]; return [{ json: { filteredTitles } }];This will result in an array of current notifications, e.g.
[ { "filteredTitles": [ "Email is not configured properly", "The app at cms.example.com ran out of memory." ] } ] The if-node checks if there's actual content. If it's empty, nothing will happen, if it's not, it will make a http request to your nfty instance and topic of your choice (saved credentials in n8n) and send the notifications:2ae64242-ff94-44d3-843d-fb0154436eed-image.png
Since I was working with readonly tokens, I had no intentions of marking the notifications as read after sending out the message. So there's room for improvement, but I thought I would throw it in here as a PoC 🙂

Improvements are welcome! 😉
TL;DR: Adjust the URLs to your Cloudrons, create and add readonly tokens, add a ntfy token to your n8n credentials and adjust the URL to your ntfy instance.
