[Nut-upsuser] Powercool UPS compatibility

Tue Apr 20 09:56:46 BST 2021

Hi all,

In the comments for https://github.com/networkupstools/nut/pull/638/ adding
support for "hunnox" subdriver I saw somebody report that the branch also
supported their Powercool branded device. I am brushing that submission
into shape to merge it, and for that matter also plan to merge the
https://github.com/networkupstools/nut/pull/1008 adding an "snr" subdriver.

So hopefully a build of NUT from the master branch after these merges would
let your deployment see your UPS better. That said, you may have to poke
the unRAID plugin maintainer to update their package.

Jim
