Either I change to use an external site to determine my IP, or I do something in WAN failover script to change what ddclient does.  Any thoughts as to best approach?  I want something automatic that will work whether using primary or failover.

I think it was at 20% left, but at that level I still have 90-120 minutes of runtime left.  Is there a setting to change when Astlinux does the shutdown?

I think I was wrong: https://networkupstools.org/docs/man/ups.conf.html
Pay attention to the "ignorelb", "default.<variable>" and "override.<variable>" parameters.

Checkout this command in CLI to get the values:

----
upsc ups@localhost
battery.charge: 100
battery.charge.low: 10
battery.charge.warning: 50
...
...
----
