Hi Roger, Hi all,
> Does upsmon.conf specify a shutdown on LB?
I think so. You mean SHUTDOWNCMD?
The relevant parts of my upsmon.conf (notifications removed):
MONITOR ups@localhost 1 upsmaster secret master
MINSUPPLIES 1
SHUTDOWNCMD "/sbin/shutdown -h +0"
POLLFREQ 5
POLLFREQALERT 2
HOSTSYNC 15
DEADTIME 40
POWERDOWNFLAG /etc/killpower
RBWARNTIME 43200
NOCOMMWARNTIME 1800
FINALDELAY 1

It's the same :-(

About half a year. But I already went into this issue some months before with
the 2.7.4 Raspbian package but havn't found the time to fix it.

With defaults its the same.
But I noticed two other details:
1. I was a bit wrong with step 7 and 8 - Looks like the UPS is "OL CHRG"
(according to display) at first but goes to battery ("OL DISCHRG" according to
nut) right when the RasPi (and nut) is booting.
2. When I pull the plug of the RasPi after UPS went down before main power
comes back (so between step 5 and 6), the UPS comes up in state "OL CHRG" and
is stable.
Maybe nut is sending `upsdrvctl shutdown` right after boot again but without
shutting down the system or sending an notification? Is there a way to check
this reliably?
