QNAP recognizing NUT | Netgate Forum
May 13, 2024 - It simply returns to monitoring the UPS as before T-0. There is nothing to cause the QNAP to restart, and it will remain powered off until physically reset. For reference, this is what you expect to happen with NUT: T-0: Mains fail, and the UPS goes on battery. T-1: The NUT server notices that the UPS is on battery during its next poll. This is communicated to all attached NUT clients.

r/qnap on Reddit: Setting up a NUT Server in Qnap
January 28, 2026 -
Good evening everyone, I'm trying to configure my QNAP TS-451D2 as a NUT server, so that the UPS in use can power a second NAS (set as a slave).
Unfortunately, when I set the IP address of the master UPS, the slave tells me that the IP is "not navigable."
I followed these instructions: https://www.qnap.com/it-it/how-to/faq/article/how-do-i-set-up-multiple-nas-devices-using-one-ups
But I can't get much out of it.
Should I perhaps install some applications in VMs or containers?
And if so, what would you recommend?
Thank you so much!

Is the second NAS also a QNAP ? (QNAP's NUT server uses a specific username to access the NUT information)

Are these NASs on the same network? I only have one QNAP NAS, so I can't recreate your scenario. Both my NUC and a Pi can recognise my NAS as a network UPS master since they're on the same LAN (IP 192.168.xxx.xxx).
Using NUT with a QNAP NAS and other devices - NAS
On the QNAP you are probably best to plug the USB from the UPS into the QNAP NAS. This will give you all the stats from the UPS on the NAS, plus the NAS will become a NUT network master, which will re-broadcast NUT requests to nominated clients. All other devices can run as NUT clients. More on forums.whirlpool.net.au

December 17, 2024 - The UPS is connected to one of the NUC proxmox servers via USB. I run NUT on that server, including the nut-server that allows other machines (such as the NAS) to access the UPS over the network as nut-clients. The problem is that QNAP makes this more difficult than it has to be.

Good luck. I tried to find a solution about a year ago and finally gave up and made my NAS the server. It works great communicating with my other NAS appliance and Windows servers sharing the UPS. I do wish you luck and if you find a solution, please post it as I'm still interested and open to other solutions.

r/opnsense on Reddit: OPNsense NUT client cannot connect to QNAP NAS (NUT Server)
May 31, 2024 -
I'm having problems connecting my OPNsense device as a NUT client to a QNAP NAS that acts as a UPS server. I've installed the os-nut plugin. My configuration is:
QNAP IP: 192.168.1.115 and OPNsense LAN IP was added to UPS Client Notification List (on the QNAP NAS)
OPNsense:
General Nut Settings:
Enable Nut: (checked)
Service Mode: netclient
Name: qnapups
Listen Address: 127.0.0.1
UPS Type: Netclient
Enable: (checked)
IP Address: 192.168.1.115
Port: 3493
Username: admin
Password: 123456
Contents of /usr/local/etc/nut/upsmon.conf:
MONITOR qnapups@192.168.1.115 1 admin 123456 slave
SHUTDOWNCMD "/usr/local/etc/rc.halt"
POWERDOWNFLAG /etc/killpower
I can't connect to the UPS and Nut Diagnostics/UPS Status panel is empty.
Broadcast message from the console:
Communications with UPS qnapups@192.168.1.115:3493 lost
UPS qnapups@192.168.1.115:3493 is unavailable
From the log:
upsmon[64406]: UPS [qnapups@192.168.1.115:3493]: connect failed: Write error: Broken pipe
The MONITOR statement (in upsmon.conf) is the exact same as the one for the nut client on a Raspberry Pi, which does connect to the QNAP NAS.
Anyone have any ideas on what I'm missing with my configuration?
