Thanks for the links, will definitely send a mail there as well.

I'm not sure if I get your idea completly right, but first I got only
one UPS and second isn't the driver from nut I posted in my first mail
already made to use both on one computer?
The way I understood the manual is that I could use nut for all devices
and put apcupsd with this driver additionally on the computer directly
connected to the UPS. I guess apcupsd would only serve as access to the
UPS while nut controlls the system shutdown and information
distribution. Would they really interfere?
