I wonder why UPSes and notebook batteries are rendered by different applications. Of course, they have different physical implementation, but the usage and goals are the same.

So, I think it would be good to have PowerDevil show me the status of my UPS, my computer is powerred from.

P.S. NUT does see the UPS state and charge and PowerDevil (battery chagre plasmoid) does not see anything.

Try installing the package: nut-hal-drivers
This will allow HAL to detect UPS'es that NUT supports, and therefore Powerdevil should be able to detect them

As I can see, HAL does not support ttySx-connected UPSes - only usb ones:

Code: Select all

pavel@host:~> rpm -ql nut-hal
/usr/lib/hal/hald-addon-bcmxcp_usb
/usr/lib/hal/hald-addon-megatec_usb
/usr/lib/hal/hald-addon-tripplite_usb
/usr/lib/hal/hald-addon-usbhid-ups
/usr/share/hal/fdi/information/20thirdparty/20-ups-nut-device.fdi


Inside file 20-ups-nut-device.fdionly USB upses are mentioned.

I installed the package nut-hal (with the deinstallation of nut and nut-classic packages). Power manager in KDE tells me that there is no batteries installed on the system still.

Unfortunately, it appears you will have to use alternate monitoring systems until Devicekit-Power becomes available, since the NUT developers are not continuing with work on the HAL components.

When NUT has appropriate components for Devicekit-Power, and a Solid backend for Devicekit-Power is available, then it should work.
