Hearth is a small home hub that watches, listens and understands the nursery so parents can rest, and their child's data stays at home. It fuses camera, sound, room sensors and the vital-sign wearable you already own into one calm notification stream, with every frame of video processed and stored inside the house.
New parents are sold anxiety. The baby-monitor market has moved from a simple radio to a camera, an app, a subscription and a cloud that stores months of nursery video and biometric data on a vendor's servers. The technically capable few solve this with weekends of open-source tinkering. Everyone else has no alternative.
Leading connected monitors stream nursery video to remote servers by default. Core features fail during outages, subscriptions rise, and some products have been bricked when the vendor moved on.
Camera, pulse-ox sock, room thermometer and sleep log each have their own app and none of them talk to each other. A parent gets four notifications about one event, or none about the one that mattered.
Single-sensor alarms fire on a loose sock or a passing car. Parents tune them out, which defeats the purpose of having a monitor.
Infant biometric and video data is routinely retained, analysed and in some cases shared under broad consent language.
Hearth connects to a nursery camera, a room sensor and optionally an Owlet Dream Sock, and runs every bit of analysis on the device.
Understood from the camera, on the hub, never uploaded.
Distinguishes a brief fuss from a sustained cry and a cough from background noise, and tells you which.
Tracks the room and can drive a fan or air conditioner to keep it in the safe range.
Flags the cues that matter, always with a snapshot for the parent to judge.
Heart rate, oxygen and skin temperature from the sock you already own, compared against movement and sound.
Every signal fused into a single state. Adult-in-room and quiet-hours awareness built in.
Answered by a small language model on the hub, from the day's event log.
Privacy is a property of the design, not a promise.
Parents are not locked into our hardware.
Hardware is the product. A pre-configured hub sold at a healthy margin over commodity components, owned outright by the customer. The subscription is a convenience, not a requirement, which is the inverse of how the incumbents work.
No. Video is processed and stored on the hub inside your house and never leaves the local network. Privacy is a property of the design, not a promise in a terms-of-service document.
No. Core function is a one-time hardware purchase you own outright. An optional Hearth Plus tier covers secure remote access, cloud-free backup coordination between family devices, priority support and early model updates. Nothing essential is behind it.
Yes. Hearth works with any standard IP camera and any common room sensor. You are not locked into our hardware and we are not locked into any one supplier.
Hearth reads heart rate, oxygen and skin temperature from the family's existing Owlet Dream Sock and cross-checks them against movement and sound, so a loose sock reads as a loose sock rather than an emergency. The product is fully functional without vitals and degrades visibly if the integration is unavailable.
No. Hearth is a parental awareness tool. It does not claim to detect or prevent SIDS and it does not replace the independent alarms on the Owlet or a parent's own judgement. Every alert is a prompt to look, and it always includes a snapshot so you can judge for yourself.
Whether the baby is asleep, restless, awake, rolled or climbing. Whether a sound is a brief fuss, a sustained cry or a cough. Room temperature, humidity, light and noise. Face-covered or uncovered. All fused into one state, so you get one calm notification about the change that matters rather than four alarms about one event.
Hearth is a working prototype on reference hardware today. A pilot with 50 to 100 households comes next, then a pre-configured hub and starter bundle with a companion app. Create an account and request access to follow the build or join the pilot list.
Hearth is being built in the open with a small group of collaborators and early supporters. Create a free ZeroState Labs account, request access, and once it is approved this address opens up to:
