Proxmox UPS shutdown signal from UPS Master (NAS)

[HeeroYuy]

Hi,

following setup: My QNAP NAS is connected to a UPS via USB, and it will shut down after 10 minutes when a power loss is detected.
Now I can activate the UPS Master in the QNAP settings. This master should inform following IP addresses about the power loss:
192.168.1.1 (router)
192.168.1.30 (Proxmox server)

Where and how can I set up Proxmox to recognize this signal and also shut down after X minutes?

My UPS has only one USB port (Eaton Eclipse ECO 800).

Hello floh8,

do you have some more information about configuration? I have the same problem as HeeroYuy. Here me post in the Germany community:

Hello dear community,

I am still new to Proxmox and Linux. I have the following constellation:

DS918+ as NUT server
Proxmox Host as NUT Client

The connection from Proxmox to the Synology DS918+ is up. I will test the automated shutdown of the Proxmox Host this evening. If I have understood everything correctly, all VM's and containers should be disconnected automatically BEFORE the Proxmox Host shuts down.

Now my 2 questions:

1. what settings do YOU have so that the Proxmox Host automatically starts up again after the shutdown when the power is back? What else needs to be set here? Does the UPS have to be shut down?

2. what setting do YOU have so that Proxmox sends e-mails about the status of the NUT connection? I have difficulties with the scripts and settings in the config files and am unsure. Sending emails from Proxmox works fine -> for backups for example.

Thank you for your help and have a wonderful and healthy week.

Ronny

P.S. So I think I have set everything, but the Promox host reports in the syslog "on battery" but does not shut down. How can I set the time between "on battery" and "shutdown"?

I found a solution by myself.
