One Nervous System for a Smart Home

A no-touch wall, a voice assistant, and a dozen live data layers that all subscribe to one data spine. Home Assistant is the brain; a hand-built SPA is the face. A context engine picks the scene from fused sensors, a self-building AI pipeline paints contextual hero art across every screen, and feeds for football (Man Utd, the EPL table, the World Cup), weather and radar, the LSN newsroom, home health, and now-playing all flow through a single seam. The hard part was never the screens — it was the data layer that makes any new surface a thin subscriber.

The Calm Wall
The Wall

A wall-mounted portrait display that shows the right thing at a glance — and never asks to be touched. A context engine derives the active scene from fused house sensors (presence, calendar, media, motion) instead of a wall clock, and an always-pinned 'Up Next' calendar spans work + personal and rolls forward to tomorrow in the evening.

What Ships
No-touch portrait kiosk with a calm, glanceable layout
Context engine — active scene from fused signals, not the clock
Always-pinned 'Up Next' across work + personal calendars
Hysteresis + confidence margins so the scene never flickers
Impact
The wall is useful from across the room without a single tap — it reads the house and shows what matters now.
