How the parts connect

CareWatch AI, wired up

Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.

Drawn from the CareWatch AI parts list. The 3D view above is built separately, from the CAD.

The program

What controls CareWatch AI

Runs on: ESP32-S3-WROOM-1

2Map the target to bed, bathroom or chair zones
3Run dwell timers with a 10 s debounce
4Raise the bathroom limit when humidity jumps
5Publish a 1-minute bin, and events at once

What you see in the app

One screen for each job CareWatch AI does.

Long bathroom visitA resident in Room 12 has been in the en-suite far longer than usual. The carer gets a prompt to knock and check.
No movementOn a quiet afternoon one resident has sat without moving for 45 minutes. The room board shows the carer which door to look in.

Not up yetAn older man living alone has not got out of bed by his usual time. The agency coordinator calls him before sending a caregiver.

What the app gets

Data CareWatch AI sends to the app
Bathroom prompt	Room 12: in bathroom 20 min	Past the limit
No-movement prompt	No movement for 45 min	Daytime check
Room board	Occupied, green	Every minute
Puck health	On battery, radar ok	Every minute
Response time	2 min 10 s	Weekly report

No camera or microphone. Only zone events leave the room. Radar fall output is dropped, never sent.

Lab updates for CareWatch AI

All lab updates

28 Oct 2026, 11:40LatestA care home or ward needs one thing at each bed that calls a resident getting up before they stand, someone on the floor and what a call is for, and fills the turn, fluid and hand-rub records, without a camera in a private room. CQC asks for the least intrusive option, a bed-exit signal is a Class I exempt bed-patient monitor (21 CFR 880.2400), and homes pay about $240 a room + $19.99 a month for a wall radar (Vayyar) on top of mats and call bells.

CareWatch AI FAQ

General FAQ

Does CareWatch use a camera?

No. CareWatch uses 60 GHz radar, which measures motion and position as data points rather than images. It has no camera and no microphone, and all detection runs on the device. Only events and activity summaries are sent to the app.

Is CareWatch a medical device?

CareWatch is designed as a safety-notification aid for carers, not to diagnose or treat any condition. It does not replace staff checks or care plans. We are reviewing the regulatory position for each market before launch.

How is it installed?

Mount the puck high on a wall or on the ceiling, plug in the USB-C supply and mark the bed, bathroom and door zones in the setup app. A room takes about 15 minutes.

What connectivity does it need?

Wi-Fi for most sites. For homes without broadband, an LTE-M option is planned. Detection keeps running on the device during internet outages.

Is CareWatch AI available now?

No. CareWatch AI is a new concept in development. Specifications are target specifications. It is a concept: we are not taking orders, reservations or deposits, and it has no ship date yet.

What warranty will it come with?

We are planning a 2-year limited hardware warranty covering manufacturing defects, with advance replacement for care providers. Final terms will be published before shipping begins.
