This guide explains how to set up a NUT (Network UPS Tools) server to integrate a Green Cell UPS with a Synology NAS. To ensure smooth communication between the Synology and the NUT server, it's crucial that the server is named "ups" in the configuration.
- A Synology NAS
- A compatible Green Cell UPS
- A server (physical or virtual) on which NUT can be installed and configured
-
NUT Installation: Ensure NUT is installed on your server. The installation process varies depending on the operating system.
-

ups.conf
) in your preferred text editor. -
Add the following configuration for your Green Cell UPS:
[ups] driver = blazer_usb port = auto desc = "PROXONE UPS" default.battery.voltage.low = 10 default.battery.voltage.high = 14 langid_fix = 0x409
