The quiet worry

You're probably thinking about it more than you let on.

If you have a parent living alone, you probably check in more than they realise. Did she get up? Has he eaten? Is the heating on?

You ring every few days. She says she's fine. But a phone call only covers so much, and there are 23 other hours in the day. Millions of UK families have the same thought in the back of their mind.

Hearth architecture
Signs to look for

How do you know when it might be time?

One incident isn't a crisis. What matters is pattern - a gradual change over weeks or months.

Home feels different

Post unopened, bins not taken out, dishes piling up.

Getting cold

House feels chilly, heating not managed well.

Mobility changes

Moving more slowly, avoiding stairs, mentioning a fall.

Social withdrawal

Calling less, fewer activities, less engaged.

Forgetting routines

Missed medications, doors unlocked, meals skipped.

Night-time changes

More frequent bathroom visits, restless nights, confusion.

How it works

Simple, private, and completely hands-off.

No technical knowledge needed. Everything arrives pre-configured and tested. Your parent doesn't need to learn anything or change their routine.

We send it ready

Every Hearth arrives with four sensors already paired to the hub. Kitchen, bathroom, bedroom, and front door. Nothing to choose, nothing to configure.

Place and connect

Plug the hub into the router. Stick each labelled sensor in its room. Scan the QR code with your phone. 15 minutes, start to finish.

It learns, you relax

Hearth learns the routine within days. You get three plain-English summaries a day, a weekly trend report, and alerts only when something seems off.

Invite your family

Add siblings, a partner, or anyone in the care circle. Everyone gets their own notifications and sees the same dashboard.

The hardware

Tiny, wireless, and built to disappear.

Each sensor is completely wireless, runs on a single coin-cell battery for years, and is small enough to blend into any room. No wiring, no charging, no maintenance.

Years of battery life

Each sensor runs on a single CR2450 coin-cell battery. Typical lifespan is 2-3 years. When it's time, you just pop in a new one - no tools needed.

Completely wireless

Zigbee mesh networking with no WiFi dependency. Sensors communicate directly with the hub on a dedicated low-power frequency. Range covers any standard home.

Position anywhere

Adhesive-backed, no drilling required. Stick them on a shelf, a doorframe, or a wall. Reposition any time. Every sensor arrives pre-labelled for its room.

Invisible to the person

Small enough to go unnoticed. No flashing lights, no sounds, no visible technology. Your parent doesn't need to know it's there - and most forget within a day.

Privacy by architecture

Your parent's data stays in their home.

Most care tech uploads everything to the cloud. Hearth is different. All sensor data is processed and stored locally on the hub - the small box sitting next to the router. Our servers never see it.

Your data stays home

All sensor data is processed and stored on the Hearth hub in your parent's home. Raw care data never leaves the house. Not to us, not to anyone.

Nothing opens the front door

The hub calls out to show you the dashboard - but nothing from the internet can reach in. No settings to change on the router. No way for anyone to connect to the hub uninvited.

We only see what we need

Our cloud service handles your account and software updates. It never sees which room Mum is in, when she woke up, or what her day looked like.

Full audit trail

Every remote diagnostic access is logged and visible to you. You can see exactly who accessed the hub and when. Transparency isn't optional - it's how we built it.

Common questions

Everything you might be wondering.

Absolutely not. Hearth uses only motion sensors, a presence sensor, and a door sensor. No cameras, no microphones, no video, and no audio of any kind.

Four rooms: kitchen (motion), bathroom (motion), bedroom (presence - can tell if someone is there even when sitting still), and the front door (open/close). From these four signals, Hearth builds a complete picture of the daily routine - wake time, room visits, outings, bathroom patterns, and sleep.

Nothing at all. The sensors work passively. No buttons, nothing to wear, nothing to charge. They simply live their life as normal.

All sensor data is processed and stored locally on the Hearth hub in your parent's home. Nothing is uploaded to the cloud. Our central service handles your account and billing, but it never sees the care data. The dashboard is accessed through a secure outbound-only tunnel - no ports are opened on the home router.

Three times a day, Hearth generates a plain-English summary of the day so far. For example: "Mum had a quiet morning - she got up around 8:30, a bit later than usual, and spent time in the kitchen. She went out mid-morning. Everything looks normal." You also get a weekly trend report that spots gradual changes over time.

£19.99/month covers everything - the hub, all four sensors, the dashboard, AI summaries, the app, and ongoing updates. There's no upfront hardware cost. The minimum commitment is 6 months. When you cancel, we send a pre-paid label to collect the hardware, refurbish it, and pass it on to another family.

Yes. The primary account holder can invite other family members by email. Each person gets their own app login and can set their own notification preferences. The whole care circle sees the same dashboard.

Yes, the home needs broadband. The hub connects via ethernet cable (included). Sensors connect wirelessly via Zigbee, which is separate from WiFi and very reliable.

About 15 minutes. Plug the hub into the router, stick each labelled sensor in its room (adhesive, no drilling), and scan the QR code on the hub with your phone. Everything is already paired before it arrives.

The hub keeps monitoring and storing data locally. When the connection returns, the dashboard catches up. You might miss real-time notifications during the outage, but no data is lost.

Hearth was founded by a doctor with experience in elderly care and geriatric medicine. The detection logic is grounded in clinical research on how changes in daily routines - sleep patterns, kitchen activity, bathroom visits, mobility - signal changes in health before they become emergencies. Built in the UK.
