Description: I found this for Home Assistant.
Wouldn’t this be a nice addition to Gladys, especially since we need to secure our systems, which is my case, and thus monitor the power supply without having to query via a PC?

There is a possible integration: Network UPS Tool

That’s a good idea. Personally, I’m currently doing it with Node-red and displaying the values in Gladys with fake MQTT devices 
Docker environment on Synology, base Gladys version
I wanted to try this solution starting from Gladys Integration everything seems normal except that Node-red goes into a loop. Connection refused…

Another example in HA:
My mistake, I thought you wanted to link Gladys and your UPS via a network connection. If I’m not mistaken, given the link you posted, you’re actually talking about a NUT integration that allows communication with the UPS connected via USB?
If that’s the case, I don’t know how that works.
Also, I don’t know what logs you shared… Node-RED’s?
Did you launch Node-RED from Gladys?
By giving us a bit more info on what you want to do, and what you’ve done, we should be able to guide you a bit more! 
Good evening,
First point:
My UPS does not have a local network connection, it is connected to the main Synology via a USB connection.
This connection controls the server in case of a power outage to prevent a disk crash. The server in turn, notifies the other servers via the local network. Personally, I have two other old servers for my backups.
The issue is that to get information or review the UPS settings, you have to unplug the Synology connection and reconnect via USB to the PC.
The goal would therefore be to delegate these reconfiguration and consultation functions to a Gladys layer and to be able to monitor via Gladys even if the PC is far away.
NUT does indeed seem to be the solution but in the form of an integration. It’s a backup power management system.
As you may have seen, this function is installed on Home Assistant.
Second point:
Given your response and out of curiosity, I tried to install Node-RED via the Gladys integration and ran into this problem…
The log comes from the gladys-node-red container line, right-click and terminal (temporary access).
Before 4.79, I already had the problem..

The Gladys-nodered installation issue has been reported and addressed. Configuration ----- Synology + nodered.

This isn’t an integration with Gladys, but in the meantime… it solves the problem…
