My pyDECNET router THEARK runs on a Pi Zero W2. Normally all happy and peachy for months
on end but from time to time it loses connection to its area router. I started with a
simple script that checked the connection from time to time and sent an email. Well now
this has grown to a full blown thing with many capabilities so I decided to bring this to
the group. I dropped it on GitHub today

and let me know what you think. Hope it is helpful to some

Nice.
On the process monitoring thing: systemctl would do that, as I understand it. That's
how I have my router set up, it's configured in systemctl and as a result starts at
system boot/powerup time.

Mike wasn't talking about process monitoring, though, but connectivity
monitoring.
I've not in general had issues with connections stop working after some
time, so I don't know what that would be about. Mike - check that you're
running a current version of PyDECnet...

I have to ask... are using Wi-Fi or have you added an USB Ethernet adapter
to your Pi Zero W2?
This could be your Wi-Fi dropping out. An examination of logging (using
journalctl) would verify this.

It’s a USB Ethernet adapter.
Yes at boot system to brings up the router but often the connection does not come up for
various reasons., thus the monitoring daemon, systemctl does not restart the service when
it goes down for whatever reason either until I reboot.
