Device health monitoring

Is there anything in development to monitor and communicate the health of devices? The smart app I used will be gone shortly, as Groovy will be gone. On numerous occasions this app has alerted me to devices that went offline and without it, I would have not known, maybe for months or longer, that this happened.

Has anyone come up with a relatively simple solution to this that doesn’t involve programming skills? The ST app does show when a device is offline, isn’t there a way to integrate a notification of this?
