Smart home, calmly.

Hearth is a single, soft-spoken app for every light, lock, and thermostat in your home. It never shouts, never nags, and remembers what you do without asking.

A SOFT-SPOKEN ASSISTANT

Your home, learning gently.

Hearth watches what you do — at dawn, at dinner, at bedtime — and slowly begins to do those things for you. No forms, no blueprints, no "set up a routine" screen.

Ambient learning

Live with it for a week. By day three, the porch light comes on as you walk home. By day seven, the kettle's ready when you wake.

No voice assistant

We are deliberately without a wake-word. If you want to talk to your house, you have many options. We think a gentle tap is usually better.

Works with what you own

Matter, Zigbee, HomeKit, and about sixty-four older protocols from your 2018 smart-plug. Walk through setup without resetting anything.

Private, on-device

Your routines live on a single small cube that plugs into the wall. Nothing leaves your home without a very good reason.

Sunset-aware

Everything colour-temperature-related respects the sun. Warm toward evening. Cooler near noon. Your eyes will thank you at 23:00.

Energy receipt

Every week, a small, honest report of what your home spent — in kilowatt-hours, in actual money, and in approximate trees.

WORKS WITH

Most of the devices
you've already bought.

Lights

Philips Hue, Nanoleaf, LIFX, Aqara, IKEA Trådfri, and most cheaper ones.

Locks

Yale, August, Aqara, Schlage — anything with Matter over Thread since 2023.

Climate

Nest, Ecobee, Tado°, and most Japanese inverter AC units via NatureRemo.

Sensors

Aqara, Sonoff, Shelly, plus your Apple Watch for sleep-aware scenes.

Bring a bit of quiet to the smart in your home.
