No, I've not done just what you're asking about, however I have a
suggestion to consider which may be in the spirit of what you're doing.
I use Raspberry Pis as the NUT master to control my UPSs, and then the NUT
client on the other systems. My UPSs are by Tripp-Lite and I have both
older serial and newer USB versions. Using the RPi3 as the NUT master has
the following advantages (to my mind):
- NUT code is fairly current due to RPi's Debian roots
- Raspbian is maintained
- Automatic updates via apticron and unattended-upgrades
- RPi is low cost and low power
- No USB to serial adapter needed
- Nice to isolate the NUT master on a separate system
One small issue is that the RPi doesn't have RS232 levels on its serial
lines, so you need a level-shifter. One that works fine is the MAX3232:
