Hi,

I'm trying to monitor My UPS PowerWalker - https://powerwalker.com/pl/produkt/10121100/ with UnRaid. Right after installation NUT and enable monitoring everything was connected and working, I could see current power and all attributes, but after a while I've got alert Lost communication

 

NUT showed current power until I rebooted the system now it shows lost communication status from a start and NUT don't show UPS LOAD:

 

Tried every trick that was written online. Change usb cable, change usb slot, change UPS type to modbus, nothing works.

 

Logs from UnRaid:

 

Any idea how to get it working correctly?

 

Thanks in advice.

As I interpret the short section of the syslog, those lines are from apcupsd plugin that is the default in Unraid.  If you are truly using NUT, you need to go to   

         SETTINGS    >>>   UPS Settings     and make sure that this setting is disabled:

 

(I use apcupsd to control my UPS for my Unraid servers, so I have it enabled!)

i've tried all the combination, NUT enabled APC daemon disabled, both disabled only APC daemon enabled and nothing works. Once I've maaged to set ups status online in UPS Settings but power had 0 state, next I managed to see power in NUT for a while but its all random.

Try asking in the Support Thread for NUT to see if there is a solution.  (For any plugin, you should find this link as shown here:)

 

Also consider contacting the vendor/manufacturer to see if their product uses a communication protocol that is supported by either of these two (apcsupd and NUT) software packages.  (They could be using a proprietary  protocol...)

hmm, it seams that my ups not showing load under 50W. When I was doing migration or something what takes more power load is visible and its over 50W. Is it possible?
