In hindsight, to chose not to include a battery may have been a poor
decision, but here I am. Also, figuring this out may help someone else
with a remote unit that is difficult to access, to replace a failed battery.

If that's not feasible, how about testing network connectivity with

Yes, I'm traveling that route, see my psudo-code solution in another post.
I am not a bash scripting guru, but, that implementation does work. Due
to cron's one minute resolution, it is not as quick as it could be. I need
bash threads. (anyone?) -- (but that is not a problem for ntp proper)
