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.

Update: There's even more :-):

upsrw ups@localhost
[battery.charge.low]
Remaining battery level when UPS switches to LB (percent)
Type: STRING
Maximum length: 10
Value: 10

You can also set variables with "upsrw", e.g. in "/mnt/kd/rc.elocal". You need the username and password from "/etc/ups/upsd.users".
