Device states
Hover or focus a square for details. Select a device to open its occupancy history. Bars mean running; flashing means offline. Maintenance takes colour priority over listing. A small clock marks an overdue snapshot; it keeps its last known colour and stops all animation. Unknown states use a neutral outline and question mark. Reduced-motion mode uses static play and offline symbols.
Squares resize to fit the available space, between 22 and 64 pixels. Large estates scroll when the minimum size no longer fits.
The app checks device states every five minutes and imports occupancy history every thirty minutes. This page checks for cached updates every minute while visible. Refresh reads the cache.
