1. 01

   The whole LaundryRoom

   A battery puck on each machine counts cycles from vibration and motor field; on washers it also checks a leak foot on the floor. The wall hub hears every puck over Bluetooth and runs every job for one app.

2. 02Brain

   ESP32-C6-MINI-1 (wall hub)

   The brain: it runs the laundryroom-hub program

3. 

   03

   Machine puck radio

   Reads the puck's sensors and leak foot, and sends each cycle and alarm

   ESP32-C6-MINI-1 (wall hub) · BLE radio · Cycle start and end, leak, battery

4. 

   04

   Vibration sensor

   Feels the drum running and wakes the puck; spots an off-balance spin

   Machine puck ESP32-C6 · I²C (SDA, SCL) · 100 Hz vibration samples

5. 05

   Motor field sensor

   Senses this machine's motor so a neighbour's shaking is not counted

   Machine puck ESP32-C6 · I²C (shared bus) · 3-axis magnetic field

6. 06

   Leak foot

   Two steel contacts just above the floor behind the washer; water bridges them

   Machine puck ESP32-C6 · 2-core lead, GPIO pin · Wet or dry

7. 

   07

   Two AA lithium cells

   Power each puck for years through a 3.3 V converter

   Machine puck ESP32-C6 · 3.3 V power rail · Power

8. 08

   LTE-M modem

   Sends the room's feed where the basement has no Wi-Fi

   ESP32-C6-MINI-1 (wall hub) · UART (TX, RX) · MQTT messages to the cloud

   All connected

   7 key parts, one program, and your phone

The idea

One wall hub and a puck on each machine: cycle counts, down machines, a free-now page and water on the floor, in one app

How the parts connect

LaundryRoom, 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 LaundryRoom

for (;;) {
  puck_frame_t f;
  while (ble_next_frame(&f, 100)) {            // signed puck adverts
    machine_t *m = room_machine(f.puck_id);
    m->last_heard = now();
    if (f.leak_wet && !m->leak) {             // water behind a washer
      m->leak = true;
      mqtt_publish_now("room/leak", leak_json(m));
    }
    if (f.kind == FRAME_END) cycles_add(m, f.start, f.end);
    if (f.peak_g > m->spin_g_p95 * 1.8) notes_add(m, "off-balance");
  }
  uptime_check(room);                         // silent while neighbours run
  supervision_check(room, 30 * 60);           // puck not heard, low battery
  if (now() - last_pub >= 60) {
    uplink_publish("room/state", room_json(room));   // Wi-Fi, else LTE-M
    last_pub = now();
  }
}

Pricing

Target pricing. For an 8-machine room, our three products bought separately (LaundroLink hub $399 + $39/month, CycleTap gateway and 8 pucks $379 + $15/month, WaterLeak monitor-only kit $499 + $99/month) add up to about $1,277 + $153/month (est.). Parts cost about $250 per room kit at qty 1 (est.).

Indicative launch pricing in USD, excluding taxes and shipping. Final pricing is confirmed before any balance is charged.

1. 29 Oct 2026, 10:55LatestOwners of apartment buildings with a shared laundry room cannot check the route operator's statement, see down machines or catch a washer hose leak early; a burst washer hose costs about $5,300 a claim after the deductible (figure attributed to IBHS), and route monitoring belongs to the operator, not the owner (LaundryRoom DESIGN.md market check).

   • Drawn idea plan (idea.json): a shared laundry room from above with four washers and four dryers along one wall, the floor drain, the folding table and the hallway door; pins for the wall hub, a puck on a washer, the leak foot behind washer 3, a puck on a dryer and the free-now sign with the fault QR by the door
   • The product picture is now this drawn plan instead of the plain fallback card; drawn from the design notes, not the CAD
   • What the plan keeps from the market work: the owner's own cycle count against the operator's statement, a leak alarm from the washer's own puck with no second radio, and a free-now page for residents
   • Next: close-out C5 (buyer review prep for sports) from 12:00; until then more drawn plans for catalogue products on the fallback card (puretrack, qualitycheck-ai)

2. 27 Oct 2026, 11:00A shared laundry room has three jobs: the owner wants to know which machines are down and how many cycles really ran, to check coins or the route operator's statement (route systems like LaundryView belong to the operator); residents want to know what is free before carrying a basket downstairs; and a burst washer hose costs about $5,300 a claim after the deductible (figure attributed to IBHS). Our own three products for it cost about $1,277 and $153 a month for an 8-machine room.

   • New product LaundryRoom: one wall hub and one battery puck per machine do the jobs of LaundroLink, CycleTap and WaterLeak in the laundry room, with one ESP32-C6 brain in the hub, one Bluetooth link from the pucks, and one app
   • Reused CAD parts unchanged: CycleTap's puck top, battery door, mount plate, anti-slip pad, machine tag and hub base and lid; LaundroLink's QR fault placard holder and free-now sign. Changed: the puck base gets a hole for the leak lead. New: a leak foot with two steel contacts just above the floor, and WaterLeak's rope clip made smaller for the lead. 12 printed parts, each one solid, every bought part fits
   • 3D view: a washer and dryer against a wall, pucks on top, the lead down the washer back to the leak foot by a puddle, the hub on the wall and the free-now sign on the folding counter
   • Dropped: LaundroLink's breaker-panel current sensors (no electrician needed now), WaterLeak's separate battery leak sensors and LoRa gateway in the laundry room. WaterLeak's riser valve stays in WaterLeak Building; LaundryRoom only alerts
   • Product page https://iemilabs.com/products/laundryroom/: $549 + $25/month for an 8-machine room instead of about $1,277 + $153/month; parts about $250 a room kit at quantity 1 (est.)
