SensingStage 2 ready, 29 Oct 2026: smart bedside locker that makes the bed bay's calls itself (9 calls, 5 alone, 4 assist; falls plan link added 30 Oct), no camera, 7 radar views checked in the CAD, $225 of parts at qty 1, margin about 44-58 % (est.); not built

CareOne

IEMI's one product for care homes and hospital wards: the bed's own bedside locker, made smart, so it watches the bed bay at night and calls the right carer itself, in one carers' app

The bedside locker at the head of every bed, at the same size and place, sees a resident sit up to leave, someone on the floor beside the bed, turns and night checks with a radar in its top, weighs each drink from the water jug and each bedside hand-rub pump, takes calls with a reason and a voice note from its key, lights each call on the locker and tells the right carer. Monitor and alert only; the bed's nurse-call cord stays.

Who buys it
Care-home groups and their night managers; then hospital wards (falls and fluids leads) and infection control teams.
Why it pays
$590 + $15/month per bed instead of $1,127 + $27/month: CareWatch AI ($349 + $19/mo), TurnCup ($199 + $4/mo) and CallNote ($99 + $4/mo) add up to $647 + $27/month per bed, plus about $480 for a plain wipe-clean bedside locker (£360 at a UK care supplier, est.), so $1,127 + $27/month.
Target price
$590 per smart locker + $15/month per bed (target)
First-minute wow
At 02:40 Mrs H sits up and swings her legs over. The floor glows amber before she stands and the nearest carer's phone says "Room 14, sitting up to leave"; the carer is there in 58 s. At 14:00 the app says room 3 has drunk 820 ml of a 1,500 ml plan.

What the research found

And how this design answers it

  • Rev A (28 Oct 2026): the care flagship is the bed's own bedside locker. Sealed top: XIAO ESP32-S3 brain, LD2450 radar behind 2 mm skins in the bed-side front corner, jug plate on a 5 kg load cell, hand-rub plate on a 1 kg load cell, 16 mm call key and voice-note mic, call light, tone, ATECC608, tamper switch, backup cells. Bed-side panel: amber floor glow
  • Makes the bed bay's calls itself: bed exit, not back, someone on the floor, calls with a reason and night checks alone; turns, drinks and bedside hand rubs assist; unsure means unsure
  • Folds BedSide, CareWatch AI, TurnCup and CallNote: the footboard hub, caster cups, wall puck and call handset are gone
  • Gaps listed: urine bags (BagPost stays listed), drips and oxygen (WardPole, DripCrown, OxyCart), the door hand-rub dispenser (RubDock), en-suite falls, bed weight
  • Stage 2 (29 Oct 2026): buyer check (bed-exit pads $39-118, Nobi lease about $240 a month, Ally acoustic monitoring on quote, plain lockers £360-450), price kept at $590 + $15/mo, prices checked ($221 parts qty 1, ATECC608 $4.95, piezo $1.50), bom.csv locker row quoted, cost table and margin, buyer FAQs and a power and size spec group
  • Market and rules check (30 Oct 2026): NHS England (7 August 2026) says bed sensors belong only inside an individualised falls plan, decided after a risk assessment and written in the care plan, and NICE NG249 finds little evidence that movement sensors prevent falls; CareOne's bed-exit, not-back and floor calls now switch on per bed from the recorded falls plan with its review date, and a new assist call flags a night pattern change for the falls plan review at handover; the REFINE trial found bed pressure sensors did not reduce hospital falls, so CareOne makes no such claim; CMS repealed the US nursing home staffing minimums (in effect 2 February 2026), so a signed night workload summary exports for the facility assessment; Sensio RoomMate added to the competitors; no new part

Use case

A 40-bed care home with two carers at night

ResidentNight carerNight managerInfection control lead

  1. 01Trigger: a resident sits up at 02:40, another holds the call key, a third has drunk little by 14:00
  2. 02Detect: the radar sees legs over the bed edge; the key and voice note give TOILET; the jug plate shows 820 ml
  3. 03Act: floor glow and the nearest carer told; the call routed with its reason; a drink reminder
  4. 04Log: signed calls, turns, fluids, rubs and night checks in one carers' app

Outcome: Carers go to the bed that needs them with the reason already known, and the charts fill themselves, with one locker per bed instead of a hub, caster cups, a wall puck and a handset

How it works

Architecture

  1. 01

    Sense: a tracking radar, two weigh plates, a call key and a mic inside the locker top

  2. 02

    Decide: the XIAO ESP32-S3 runs the bed, floor, plate and call models and says unsure below the line

  3. 03

    Show: call light, floor glow and a tone on the locker itself

  4. 04

    Tell: signed calls over staff Wi-Fi to the carers' app, escalated after 2 minutes

Hardware

Open risks we are working on

  • Radar bed-exit and floor tracks are unproven in shared bays and with a carer already at the bed; those calls go out as unsure
  • Turns seen by radar are less certain than load cells under the bed (est. 80 %); the carer confirms
  • The jug must stay on its plate; a jug carried away reads as unsure, not as a drink
  • Not a fall detector, nurse-call system or medical device beyond a Class I exempt bed-patient monitor: monitor and alert only
  • Care-home buying is per group and slow; the first pilot is one unit of 20 beds
