ex2-ultra & apcupsd

Has anyone successfully installed and used apcupsd on a WD mycloud ex2-ultra?
I am using apcupsd on a fedora machine as the UPS master and wish to have the my cloud ex2-ultra work as a slave.

See the dedicated EX2 series subforum were people more knowledgeable about that device may be able to assist. Or where there may be similar past discussion on the issue (see forum search feature, magnifying glass icon upper right). This subforum, My Cloud, is generally for the single bay/single drive My Cloud units.
