UPS notifications

[oz_zi]

Hello there

I just hooked up my APC bx750 via USB to my NAS. I was pleasantly surprised to get email notifications from hexos (see attachment), however I am unsure if it is reading the values correctly:

- why is it telling me i need a battery replacement, it is brand new

- why is it taking me battery is low while also reporting 100% charge

 

Any inputs are welcome 😊

Hey, yes unfortunately this seems to be normal for BX APC UPS. Those UPS are not the best ones and the driver does not work very well with them. 

The problem seems to be that the USB part of the UPS keeps disconnecting and reconnecting every couple of seconds leading to this messages. It's a known problem.

My advice would be, if you can still return it, do so and try looking for an Eaton UPS or similar.

I have the same issue with my APC UPS.
From some previous investigation on that topic, I found that the issue might be caused by the Network UPS Tool driver, and a new version might fix the issue.

The NUT version in TrueNas is linked to the Debian version, and Debian Trixie upgrades the driver to 2.8.1-5
Should be available in Truenas Halfmoon (26.04)
