Hello Carsten, That's what I did but for a much simpler setup. I live in an area 
with a lot of lightning, and my shutdown criteria is to be able to shut down 
repeatedly during an electrical storm.  The NOTIFY and CMDSCRIPT and the 
upssched-cmd logic are written up in detail in chapter 7 of 
https://rogerprice.org/NUT/ConfigExamples.A5.pdf .

Chapter 8 contains a detailed description of a hypothetical installation fed by 
multiple UPSs.
