[Nut-upsuser] Problems with NUT on Raspberry Pi

OK, reporting back. Just tested the setting battery.charge.low=70. UPS goes 
down from 100 to 70 and obviously the NUT-server begins shutdown the system. 
UPS is turned off and .... on again immediately.
I really have no idea, what the problem is, ups.delay.start shows "0".

Any suggestions? Thanks!

Here is the parameter report of the ups:

battery.charge: 47
battery.charge.low: 10

Btw: The problem with not connecting to the ups after reboot could be solved 
by set "LISTEN" to By now the NUT-Server starts after each reboot 
of the pi.

  upsrw -s battery.charge.low=50 -u <ups-user> -p <password> <my-ups>

Check with

  upsc <my-ups> battery.charge.low
