NUT Plugin not properly working

[h.bork]

After installing the nut-plugin I encountered some serious problems. I finally found out that the ups.conf file contains a duplicate entry:

[CS350]
driver=usbhid-ups
port=auto
[CS350]
driver=apcsmart
port=auto

During startup the system complains about this duplicate entry and tries to use the apcsmart driver which does not work, so nut_daemon does not run.

If I delete the second half of the ups.conf file and restart net_upsmon everything runs fine.

But ... after a reboot the ups.conf contains the duplicate entry again and the ups connection fails.

Does anybody know where this duplcate entries are saved besides ups.conf ? It must be somehow restored during boot and I don't know how to get rid of it. I tried every alternative uninstalling and reinstalling the plugin but no success.
Can anybody help ?
Thank you.

You enabled both drivers in the UI, just disable apcsmart

Thank you, that solved it.
I was not aware that it is possible to enable more than one driver.
Does that make sense ? If not, it should be prevented in the UI.

Didn’t know about the double driver. Anyway, I still keep seeing a blank page, no diagnostics. Browser seems to hang too.

Then your driver doesnt work with the UPS. Nut Tools are badly maintained (software, not plugin)

It's a APC Smart-UPS 1500.
The funny part is that I recently changed my hardware. Did a complete new install from scratch and imported my config. Before I could see the UPS status but I'm not sure I was using NUT.

Did you try the usbhid driver? Unplug and plug cable again? Reboot?
