1. 01

   The whole ParentHome

   One hub on the nightstand weighs and photographs the pill box, hears the oxygen cart and the rollator over a short radio link, sees a night-time get-up, and sends everything to one family app.

2. 02Brain

   XIAO ESP32S3 Sense (hub camera head)

   The brain: it runs the parenthome-hub firmware program

3. 

   03

   Pill tray scale + camera

   Feels a dose leave the weekly box; the camera says which compartment

   XIAO ESP32S3 Sense (hub camera head) · HX711 two-wire (GPIO), mast cable · Weight readings and photos

4. 

   04

   Oxygen cart scale

   Weighs the backup cylinder: hours left and real flow

   XIAO ESP32-C3 cart node · ESP-NOW radio (2.4 GHz) · Grams left every minute

5. 05

   Hub power and mains sense

   Keeps the hub on in a power cut and starts the oxygen alert

   XIAO ESP32S3 Sense (hub camera head) · USB-present pin to GPIO · Mains on or off

6. 

   06

   Rollator HandlePod

   Metres walked, gait speed, brakes parked, walker down

   XIAO ESP32-C3 HandlePod node · ESP-NOW radio (2.4 GHz) · Walk summaries and alerts

7. 07

   Bed eye

   Sees legs swing down over the bed edge at night

   XIAO ESP32S3 Sense (hub camera head) · I²C over a 0.6 m 4-core cable · Distance readings

8. 

   08

   Hub screen and chime

   Next dose, oxygen hours left, walking today; one chime for all

   XIAO ESP32S3 Sense (hub camera head) · SPI and GPIO, mast cable · Screen image and chime

   7 key parts, one program, and your phone

How the parts connect

ParentHome, 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.

The program

What controls ParentHome

for (;;) {
    if (tray_step_settled()) { slot = changed_compartment(photo()); send("dose", slot); }
    while (espnow_rx(&m)) {                       // cart and HandlePod
        ack(m);
        if (m.src == CART)   o2 = hours_left(m.grams, m.flow);
        if (m.src == WALKER) walk_update(m);       // metres, speed, brakes, down
    }
    if (night() && bed_eye_legs_down()) { espnow_tx(WALKER, LAMP_ON); start_getup_timer(); }
    if (getup_timer_done() && !walker_moving()) chime("walker");
    if (!mains_present()) { chime("power"); epaper_show_o2(o2); send("power_cut", o2); }
    if (due(10 min) || changed()) epaper_show(next_dose(), o2, walk_today());
    mqtt_flush();                                 // Wi-Fi, MQTT over TLS

1. 28 Oct 2026, 05:15LatestOne product for an older parent's bedside (owner decision, 27 Oct 2026).

   • Its jobs now run in BedsideOne, the smart bedside table: /products/bedsideone/

   See it in 3DFull research and design

2. 27 Oct 2026, 08:30Families looking after an older parent at a distance often face three worries at once: were the pills taken, how long will the backup oxygen last in a power cut, and is the parent still walking safely, especially on night toilet trips. Today that means a pill dispenser subscription (Hero $29.99-44.99 a month, herohealth.com), a medical alert ($25-29 a month, AARP 2026) and nothing for oxygen or walking; our own three products for it cost $447 and $14 a month with three apps.

   • New product ParentHome: one hub on the nightstand (PillPerch's base, tray and camera head) with one brain does the jobs of PillPerch, OxyCart and PaceRoll, with one Wi-Fi link and one app
   • Reused CAD parts unchanged from the three products, plus a new hub case with a cable port and a new bed eye (case and lid) that moves PaceRoll's bed sensor onto the nightstand side; 17 printed parts, each one solid, every bought part fits
   • 3D view: a parent's bedroom with the bed, the hub on the nightstand with a weekly pill box, the bed eye beside it, the oxygen cart next to a concentrator, and the rollator parked by the bed
   • Dropped: OxyCart's FlowTee box (the hub senses a power cut itself), the bed sensor's own chip, batteries and buzzer, and PaceRoll's Home Node; the cart and rollator now talk to the hub by short-range radio instead of Wi-Fi
   • Product page https://iemilabs.com/products/parenthome/: $329 + $6/month instead of $447 + $14/month; parts about $289 at quantity 1 (est.)
