Caffeinate

Caffeinate keeps your Mac awake from a Stream Deck key. Press to add an hour of wakefulness and the key becomes a live countdown timer showing the time remaining. Built on the native macOS caffeinate command, so the wake lock is reliable and can never leave your Mac stuck awake.

Included actions:

Caffeinate Timer — press to add an hour (press again to stack more). The key shows the remaining time (42m, 3h 25m) on a green background while active, and a coffee cup with +1hr while idle. Hold about a second to cancel — the key flashes a red ✕. Hold while idle to arm "sleep when the timer ends" for one run; a crescent badge shows while armed. Multiple keys mirror the same timer.

Sleep — put the Mac to sleep immediately, cancelling any running wake timer first.

Sleep Displays — sleep every monitor while the Mac and the wake timer keep running; any input wakes the screens.

Requirements: macOS 10.15 or later. Uses the built-in caffeinate and pmset tools — nothing else to install.

Support a few extra tiles and functionality -- "turn off all screens", "caffeinate, then go to sleep after", "immediately send mac to sleep"
