This was a solved problem long ago - page/text the person responsible for that facility. If Fac. Man. is too lazy to properly-staff critical things, they deserve every pain they encounter.

All of this remote crap is meant to try to eliminate a physical presence on-site, which is stupid because when things eventually break, a physical presence is required on-site anyways.

One of my jobs in aerospace is systems reliability - an unstaffed system is not a reliable one.
