A Home That Speaks
Only To Itself.
Our sensors talk to one another over a private, encrypted mesh that lives entirely inside your walls — no cloud, no cameras, and so light it never touches your Wi-Fi.
Explore the systemThe devices in your home
Small, quiet, camera-free sensors.
Each one does a single, simple job and shares only what's needed — a presence, a temperature, an open door. Nothing watches. Nothing listens.
The Dísir hub
The brain that lives in your home. It forms the network, holds the encryption keys, and does all the thinking — on-site, never in the cloud.
Smart plugs & switches
Always-on, mains-powered helpers that also relay the mesh — every one quietly extends range and strengthens the network.
Smart lighting
Mains-powered bulbs that ease the path to the bathroom at night and warm a room when a fall is detected — and, always on, they relay the mesh too.
mmWave presence & fall radar
Senses presence, motion and falls through the air itself — no lens, no recording. Battery-light, room by room.
Door & window contacts
A tiny magnet pair notes when a door opens or closes — front door at 3 a.m., the medicine cabinet, the fridge.
Motion sensors
Confirms movement through a space so the home understands the rhythm of a normal day — and notices a quiet one.
Temperature & environment
Watches for a cold house, a hot stove left on, smoke or a water leak — the conditions that turn into emergencies.
How it all connects
A self-healing mesh, built on Zigbee.
Instead of every device shouting to a distant server, each one passes quiet messages to its neighbors. The signal hops device to device until it reaches the hub — over a low-power radio designed for exactly this.
Coordinator
One per home — the hub. It forms the network and is the trust center that holds every encryption key.
Routers
Mains-powered devices that stay awake and relay messages, extending range and giving the mesh many paths.
End devices
The battery sensors. They sleep to save power, wake to report, and lean on a nearby parent to pass the word along.
Encrypted, end to end
Locked at the door — and the key never leaves.
Every message between devices is scrambled with AES-128 encryption the moment it's sent. Even within your own walls, the signals are unreadable to anyone listening.
The hub is the network's trust center — the only thing that holds the keys. They're created and kept inside your home, never uploaded, never shared, never sitting on a company's server.
Light on your network
It won't slow down your Wi-Fi.
The mesh rides its own low-power radio — completely separate from the Wi-Fi your family uses to stream, call and browse.
And the messages are tiny. A door opening or a fall alert is a few bytes — not a video feed. Where a streaming camera sends gigabytes a day, these sensors send a whisper.
Data sent over your home, per day
Resilient by design
If one path drops, it heals itself.
Because every router offers another route, a single device going quiet doesn't break the system — the mesh simply finds a new way around. And since the thinking happens on the hub, it keeps working even when the internet doesn't.
Self-healing mesh
Messages can travel many routes. If a device drops or a route is blocked, the network reroutes automatically — no call to support, no downtime.
Works without the internet
The hub does the sensing, the thinking and the alerting on-site. A storm, an outage or a dropped connection can't switch your safety net off.
Everything stays under your roof.
The same safety the cloud promises — without the cameras, the corporate servers, or the data that never comes home. Just a quiet, private network that watches over the people you love and answers to no one but you.
