ZWave - Automated failure alerts possible?

I am now fully plugged into Zwave protcol with door sensors, pir, push button devices and extenders. When it works is great but every say 3-6 months I notice that something fails, either a device or whole network. 100% of the time I can resolve this with a hard reboot of my hassio server.

Is there a way to get automated alerts when there is a failure, I typically find out by chance but should I be scanning devices for state == X and alerting when this happens? Conscious of not generating too many false positives as well.

Thoughts welcome.

What zwave flavour are yoy using? You might start with the watchdog switch in the addon then?

Its not Zwave JS. Whats the watchdog switch - where can I get this component ? Txs

What is it then?
