Online alarm clock for 2:47 am
Pause the checks you are already working through when the 2:47 am alarm sounds, then turn your attention to the Waikato hydroelectric station handover. That interruption gives you a clear point to collect the current operating notes, unresolved issues, and anything the incoming shift needs before 3:00 am. The round hour can then mark the transition from briefing to full responsibility.
Keep the alarm audible while you finish the task in front of you, especially if headphones are connected nearby. Sound can be routed to them without an obvious sign, leaving the control room quiet even though the alarm has triggered. Check the selected audio output and set a practical volume before relying on 2:47 am. A browser alarm cannot safeguard the handover if the browser session stops running or the computer goes to sleep, so use an independent backup where missing the changeover would disrupt work.
Stepping outside briefly during a Waikato night shift can feel different from the controlled air indoors. At this hour, damp air may settle around exposed walkways, railings, and vehicle surfaces. Allow a moment for your eyes to adjust, use the marked route, and keep a light layer handy if the handover requires moving between buildings before 3:00 am.
