StageTuihm – a self-hosted confidence monitor and speaker countdown

StageTuihm is a lightweight WordPress plugin for live events: a fullscreen stage display (countdown + progress bar) paired with a remote organizer control page.

You can load an agenda with multiple slots, then play any slot at any time, pause/resume, jump to previous/next, and trigger predefined or custom flash messages (“Thank you!”, “Time over!”, “Next please”).

Includes an optional auto end-of-slot flash (with repeat during overtime), and a light/dark display theme.

Wake-lock is best-effort (browser-dependent). For real reliability, also disable sleep on the display device at OS level.
