Good news, with the UPS on battery power, /lib/nut/tripplite_usb -a
tripplite -k -DDD *does* shut the UPS down:

# /lib/nut/tripplite_usb -a tripplite -k -DDD
Network UPS Tools - Tripp Lite OMNIVS / SMARTPRO driver 0.20 (2.7.2)
Warning: This is an experimental driver.
Some features may not function correctly.

Driver exited and UPS shut down a little after 64 seconds.  Will continue
with additional testing to make sure all the components work together.

As background, the intended application is to use the Raspberry Pi as the
NUT master controlling the UPS while the NUT slave is running on an ESXi

Thanks for the help!
