Set the alarm for 2:13 a.m.

Web alarm clock for 2:13 a.m.

Before handing the watch to the next person, you set a 2:13 am alarm so the water pump starts ahead of the scheduled brownout. Leave a clear note about the switch or valve they must handle, and confirm who will respond when the alarm sounds. That gives the incoming person a definite task before 3:00 am instead of relying on a sleepy verbal reminder.

Because the pump may need attention while other people are asleep, match the alarm tone to the setting. A gentle sound can suit a quiet room when the person taking over is nearby; a persistent tone makes more sense if they may be outside or around running equipment. Test the volume during the handover, then keep this page active and the phone awake. If the browser is closed or the phone sleeps, the pump reminder may never sound.

During a 2:13 am handover, keep the written pump instructions readable without flooding the area with screen light. Lower the display brightness before passing the phone across, use the warmer colour setting if available, and enlarge the note rather than bringing a bright screen close to your eyes. Once both people have checked the alarm time, place the phone face down but within hearing range so its glow does not dominate the dark room.
