I see a NUT configuration in /usr/syno/etc/ups. The DSM configuration UI only lets you set the IP of the NUT server; the UPS name is hardcoded to "ups", the username is hardcoded to "monuser" and password to "secret".
I renamed my UPS on my NUT server and added the monuser user, and now the Diskstation logs into upsd as a slave OK.
