I don’t really have any issue for what the software is supposed to do. I can access my instance, read and edit, templates and queries work fine.
But overall the user experience is not so good on mobile. On desktop it is really easy to navigate my notes, specially so because of the great support for keyboard shortcuts. Now for mobile it doesnt feel too good. Navigation works but the interface is too small - making tapping a bit clunky. I also find it uncomfortable to use for to do lists - things like groceries lists that I need on the go. Sometimes toggling works fine if touch but sometimes it switches to view mode.
I really dont think any of that is an issue with the software itself. Its just the format I guess? I still use silverbullet and Ive never tried anything as good for organizing work stuff. But I still wish something more “native” for android.
Have you played around with Grafana? It really is quite simple if you have prometheus already working.
For a home lab environment you dont even need to use prometheus-alertmanager. Grafana can handle alerts as well.
Grafana also has hundreds of pre-made dashboards you can import. Node monitoring is quite straightforward.
Assuming you have prometheus good to go, all you need to do is go to Grafana - Datasources, create a new datasource, point to your prometheus instance.
Then you can import the dashboards you want.
Now you can setup your alerts - you can use SMTP, telegram, slack among others for your notifications.
