Living Layer gives everyday objects a memory, so your smart home can react to them.

Smart homes detect motion, open doors and flipped switches. But they don’t know your mug is on the desk, your monitor has been on for three hours, or your milk expires tomorrow. A camera can see these things, but sending every frame to a vision model is slow, expensive and hard on privacy. And when AI turns on a light, the reason is often unclear.

Living Layer turns an ordinary camera into a working model of your room. Mount it in a corner, calibrate it once, and see furniture, objects, people and pets in an isometric twin. You confirm which outline is your mug, keeping you in control of identity. Then draw zones and describe what should happen: “When my mug is on the desk, turn on the desk lamp.”

It runs on your own machine and keeps watching with no browser tab open. Frames are matched locally. Meta’s models are called only with your permission, within a daily spending limit you set. Every decision is saved with its reason, so you can see why a light came on.

Zones, objects, their stats and who’s home appear as Home Assistant entities, ready for your existing automations.

Each object keeps a small history: when your mug was last used, how long a screen was on, or which food expires first. Ask the room questions in plain language, get gentle reminders from a room coach, or edit its models with an AI brush.

A bundled synthetic demo lets you try the whole loop without an API key, camera or lamp.
