Joe,

Roger has a good point - the SHUTDOWNCMD should work as long as the master system waits for the "OB LB" state, and doesn't shut down early (say, at 30% battery remaining, but the UPS waits for 20% before declaring LB).

I have never used a Synology box, but I vaguely remember them not using the NUT LB state. (That might have been covered in one of your links, but I haven't had a chance to look through all of them.)
