Your home already knows you're there. Now it can act on it.
Stillsense turns your existing Wi-Fi into whole-home presence sensing — so your lights, heating, and automations respond to where people actually are. No phone in your pocket, no wearable, no motion sensor in every room. And no camera, ever.
Every smart home struggles with one simple question: is anyone home?
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. Presence is the trigger almost every good automation depends on — and it's the thing smart homes still get wrong.
One quiet sense, your whole home responds.
Presence is the input almost every automation wants. Stillsense gives your home a dependable one — device-free and whole-home.
Lights that follow people, not movement.
Because Stillsense senses presence — not just motion — rooms stay lit while you’re still and go dark when you actually leave. No more waving at a sensor in the dark.
Heating that knows when the house is empty.
Stillsense tells your system when rooms are occupied and when they’re not, so heating eases off in empty spaces and comes back before you do.
Home and away, without a phone.
Reliable whole-home occupancy means “everyone’s out” and “someone’s home” become automations you can actually trust — for security routines, energy, and comfort.
Room-level, from what you already own.
Presence across the whole home from your existing Wi-Fi and a small sensor or two — not a device in every room.
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 — studies of Norwegian households during the energy crisis found double-digit reductions in peak demand from smarter, responsive control. 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.
How whole-home Wi-Fi sensing stacks up.
Other sensors are good at what they do — Stillsense's edge is covering the whole home, device-free, from the network already there.
| PIR motion sensors | mmWave presence (e.g. Aqara FP2) | Phone-based presence | Stillsense | |
|---|---|---|---|---|
| Detects a still person | No | Yes | n/a | Yes |
| Whole-home from few devices | No (one per room) | No (one per room) | Whole-home, coarse | Yes |
| Works without a phone/wearable | Yes | Yes | No | Yes |
| Uses hardware you already own | No | No | Phone | Mostly — your Wi-Fi |
| No camera | Yes | Yes | Yes | Yes |
mmWave sensors are excellent and inexpensive — but they're per-room and need mounting and wiring. Stillsense's edge is covering the whole home, device-free, from the network that's already there.
Fits the home you've already built.
Stillsense is designed to slot into the smart-home platforms you already use, exposing presence as a signal your automations can act on — locally, in real time.
- Built for Matter and the open smart-home ecosystem
- Designed to work with Home Assistant and the platforms enthusiasts actually run
- Local-first: presence is computed on the edge, in your home
- For ISPs and platforms: a software feature on the Wi-Fi hardware already in millions of homes (see Partners)
Whole-home awareness, zero surveillance.
Stillsense knows where people are without ever knowing whatthey look like. There's no camera and no microphone — just presence, worked out on a device in your home and kept there. The most aware home on your street can also be the most private.
- No camera
- No image, ever
- Processed locally
- Your data stays home
We're rolling out carefully, and honestly.
Stillsense for the home is in early access. Presence, motion, and occupancy are what we're putting in people's hands first; richer features will follow as we validate them. We'd rather earn a reputation for things that quietly work than ship a long list that doesn't. Join early access and help shape what comes next.
