Hi, I'm struggling with a peculiar issue with my UPS. After a power outage, the devices powered by it properly shut down via nut. Eventually, the UPS also goes down. Power is still out, however, roughly 40 seconds after the UPS shut down, it turns back on and it starts supplying power to the load, thus turning back on the devices attached to it. This is obviously not something I want. In trying to figure out the problem, the closest I've come was the ondelay parameter, but that only comes in play after the power returns, so it shouldn't apply here.
The UPS in question is a CyberPower Value600ELCD. Its USB port is
connected to my router which runs an up-to-date Debian testing with
nut-{driver,monitor,server} version 2.7.4-8 installed via apt. I'm
pasting ups.conf below and attaching output from upsc, upsrw and
/lib/nut/usbhid-ups -DD -a cyberpower.
root@e3845:/etc/nut# egrep -v -e '^$|^#' ups.conf
maxretry = 3
[cyberpower]
driver = usbhid-ups
port = auto
offdelay = 20
ondelay = 60
default.battery.charge.low = 40
default.battery.charge.warning = 50
Any idea what could be going on here?
Thanks
