01
The whole BedSide
One hub on the footboard reads the bed cups, the bag hook, the call handset and a room radar, hears the Dock at the door by radio, and sends all five jobs to one app.
02Brain
ESP32-S3 (ESP32-S3-WROOM-1-N8R8) in the footboard hub
The brain: it runs the bedside-hub program
03
Four load-cell caster cups
Weigh each bed leg: turns, bed exit, in-bed movement
ESP32-S3 hub · 4-core cable to an HX711 channel each · Weight on each leg, 10 times a second
04
Room radar
Sees people moving in the room, visits to the bed, and an empty room
ESP32-S3 hub · UART · Up to 3 people, position and speed
05
Call handset
Call reason, voice note, "Help is coming" light, dropped-handset alert
ESP32-S3 hub · 8-core cord: I2C, mic line, light; the call loop goes straight to the wall jack · Key pressed, voice, fall flag
06
Bag hook on the bed frame
Weighs the night drainage bag: mL, emptyings, no drainage
ESP32-S3 hub · 4-core cable to the fifth HX711 channel · Bag weight
07
Hand-rub Dock at the door
Counts rubs by weight and says when it will run empty
ESP32-S3 hub · ESP-NOW radio (the Dock keeps its own small chip) · Each rub in grams, grams left
08
TurnClock screen and buttons
Shows last turn, next due, bag mL and open calls; ACK and TURNED
ESP32-S3 hub · SPI and GPIO pins · Screen updates, button presses

All connected
7 key parts, one program, and your phone
What it is
One bedside system for a care-home room that does five jobs from one hub on the footboard.
What it does
Who it's for
Care homes, nursing homes and assisted-living operators who must show turning, output, call and hand-hygiene records.
How the parts connect
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.
The program
void loop() {
Bed b = cups.read(); // 4 x HX711: total kg + centre of pressure
float ml = bag.read_ml(); // 5th HX711, tare = empty bag
Tracks t = radar.read(); // LD2450: up to 3 people
Key k = handset.poll(); // TCA9534 keys, LIS3DH free fall
while (Rub r = dock.next()) visits.add_rub(r);
turns.update(b); // side change with total kg steady = turn
if (turns.due()) alert(TURN_DUE, turns.side());
if (b.empty() && t.none() && away.minutes() > usual.away) alert(OUT_LONG);
if (bag.no_drain_hours() > plan.no_drain) alert(CHECK_CATHETER, ml);
if (k.pressed) call.raise(k.reason, mic.note_if_held());
if (k.dropped) alert(HANDSET_ON_FLOOR);
visits.update(t, b); // second person by the bed = a care visit
clock.show(turns, ml, call.open());
}To your phone
Carer phones (Android/iPhone) and a browser at the nurse station
One screen for each job BedSide does.
TurnsTwo residents on Wing B have lain on one side for two hours. The cups saw no shift, so the TurnClock and the carer's phone say a turn is due.
Call with reasonAt night the resident in room 7 presses TOILET on the handset and records a short voice note. The carer knows why before she walks in.
Night bagOvernight the bed-frame hook weighs room 12's drainage bag. When it stops filling for longer than usual, the night carer is asked to check the tube.
Room activityThe cups say room 9's bed is empty and the radar sees one person in the bathroom, far longer than her usual 8 minutes.
Hand rubThe dock under room 7's door dispenser counts each rub while the radar counts carer visits. The manager sees the room's rate, never who rubbed.
App screens with sample data. The interface is in development.
| Call | Room 7 · TOILET · voice note | Each press |
|---|---|---|
| Turns | Last turn 1 h 40 min ago, left; next due 22:30 | Each change |
| Bed and room | Out of bed 26 min, nobody in the room | Each change |
| Night bag | 640 mL, emptied 06:10 (520 mL) | Every 10 min and each emptying |
| Hand rub | Room 7: 9 rubs, 11 visits this shift; refill Thu | Each shift |
No camera and no recordings except the voice note the resident chooses to make. Hand-rub counts are per room, never per carer.

From the product lab · ideation phase
It does the job of CareWatch AI (room activity, time out of the room), TurnCup (turns and bed exit), CallNote (call reason, voice note, Help is coming), BagPost (night-bag output) and RubDock (hand-rub count and refill) at one bed. Those cost $985 + $36 a month together; BedSide is $449 + $14 a month.
Yes. Each key closes the nurse-call loop through its own plain switch straight to the 1/4" jack. The hub only adds the reason, the note and the light.
No. It monitors and alerts only: turn reminders, bed exit, time out of the room, no drainage. It makes no fall, pressure-injury or diagnosis claim.
No. The bed is weighed and the room is seen by radar. Hand-rub counts are per room and per visit, never per carer.
There is no bathroom sensor. An empty bed and an empty bedroom for longer than usual is reported as "out of the room", so the carer checks.
No. It is a concept in design. Specifications are targets. We are not taking orders, reservations or deposits, and it has no ship date yet.
