   The whole PoolDeck

   One DeckHub on the fence post by the pool pump hears the gate and the far fence camera, reads the pad's leak pucks and pipe probes, and fills one app.

   The brain: it runs the pooldeck-hub program

   Fence strip camera

   Photographs the 900 mm strip outside the fence six times a day

How the parts connect

PoolDeck, 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 PoolDeck

void loop() {
  while (espnowQueue.pop(&msg)) {          // LeafPod and far ClearZone pod
    if (msg.type == GATE_CLOSE) gate.update(msg.result, msg.secs);
    if (msg.type == ZONE_OBJECT) zone.add(msg.post, msg.thumb);
  }
  if (padWet()) pad.wet(pumpRunning());     // puck contacts on GPIO, wake interrupt
  if (every(5 * MIN)) {
    temps.read();                           // OneWire: return line + motor shell
    pad.update(temps.water, temps.motor, temps.air);
  }
  if (zoneDue()) zone.checkFrame(esp_camera_fb_get());
  for (Alert a : rules(gate, zone, pad)) mqtt.publish("pooldeck/alert", a.json());

1. 28 Oct 2026, 06:40LatestOne product for the home pool (owner decision, 27 Oct 2026).

   • Its jobs now run in PoolOne, the smart pool gate: /products/poolone/

   See it in 3DFull research and design

2. 27 Oct 2026, 13:25A family with a backyard pool needs three things checked that they now check by eye: that the self-closing gate really shut, that nothing climbable is left against the fence, and that the pump pad is dry. A dripping pump seal wets the motor bearings and shortens the motor's life, and the leak often drips down unseen (VEVOR pool pump guide); faulty gates and climbable objects are the top pool barrier faults (Royal Life Saving WA). Our own two products for this cost $398 with two apps.

   • New product PoolDeck: one DeckHub on the fence post by the pump runs the gate, fence-strip and pump-pad jobs, with one app and no subscription
   • Reused CAD parts unchanged: PoolGuard LeafPod, PostTag, ClearZone pod and wedges. New CAD parts: a longer DeckHub case and lid with a socket for the pad lead and a gland for the power lead, and a pad leak puck that holds two stainless contact heads just above the slab. The WaterLeak pipe clip is resized for pool pipe. 11 printed parts, each one solid, every bought part fits
   • 3D view: a pool deck with a glass fence, the gate with its pod, the equipment pad with pump, filter and return pipe, the hub on the pier beside it and a far fence pod
   • Dropped: WaterLeak radio, gateway and building valve parts, and PoolGuard commercial camera add-on and wristband (a different buyer)
   • Hardware: parts about $168 a kit (est.); priced $249 against $398 for the two products separately; product page, parts list, how-it-works and design notes added
