Presence is the input every smart home is missing

Almost every good automation depends on one simple fact: is anyone home, and which room are they in? It's also the thing smart homes still get wrong.

Why presence is hard today

Motion sensors lose you the moment you sit still, so the lights switch off while you're reading. Phone-based presence is clumsy and stops at the front door. And getting real room-by-room presence usually means buying, wiring, and hiding a sensor in every single room.

Stillsense senses presence — not just motion — across the whole home, from the Wi-Fi you already own and a small sensor or two. Rooms stay lit while you're still and go dark when you actually leave. No waving at a sensor in the dark.

In a country that heats with electricity, presence is money

When your home runs on spot-priced power, heating empty rooms is one of the most expensive habits in the house. Presence-driven heating is among the most effective ways to cut that waste — and Stillsense gives your energy automations the one input they've always lacked: a dependable, whole-home answer to is anyone actually here?

Savings figures describe published research on responsive heating, not a Stillsense-measured result.

Fits the home you've already built

Stillsense is designed for Matter and the open smart-home ecosystem, and to work with Home Assistant and the platforms enthusiasts actually run — local-first, computed on the edge. The most aware home on your street can also be the most private: no camera, no microphone, just presence, kept at home.
