Your front door is the most important threshold in your home. It knows nothing.

Smart home systems detect arrival 200 metres away. Motion sensors cannot tell people from cats. Nobody knows when parcels arrive, how long they sit outside, or when they disappear.

Smart mats exist before DoryMat. Market is open.

Peace of mind at every step.

From footstep to notification in under two seconds. No Wi-Fi at the door. No installation. Just place it and it works.

👣

Pressure detected

64-point sensor grid reads pressure signature every 500ms

🧠

Classified on device

ESP32-S3 distinguishes footstep, parcel, cat, wind — no cloud needed

📡

BLE to your phone

Event relayed via Bluetooth 5.0. HomeKit triggers locally in milliseconds

🔌

APIs cross-reference

Server checks carrier tracking, weather, calendar context in background

📲

Calm notification

“Ella arrived home at 3:42pm.” No alarm. Just awareness.

Built in layers. Intelligent by design.

Every component engineered for purpose — from the natural coir surface to the sensor puck inside the weatherproof base tray.

DoryMat exploded view showing all five layers
Hardware · Exploded View

Five layers. One seamless mat.

Top to bottom: premium natural coir → pressure sensor grid → protective foam → weatherproof base tray → smart sensor puck with optional piezo energy harvesting tiles. Everything hidden. Just a mat.

DoryMat weighing a 2.7kg parcel at the front door
Package Mat · Weight Detection

2.7kg. DPD. Your ASOS order.

The Package Mat’s four-point load cell array reads weight to ±50g. The moment a parcel lands, Dory cross-references your active tracking numbers and names the order — before the driver is back in his van.

DoryMat footstep-powered piezoelectric energy harvesting
Power · Piezoelectric Harvesting

The mat partially powers itself.

Optional piezoelectric tiles harvest energy from every footstep, extending battery life by up to 30%. A completely unique story in the smart home market — the detail that earns Wired and Dezeen coverage.

DoryMat weather alert - rain expected at 3:16pm
Intelligence · Weather Alert

“Rain expected at 3:16 PM.”

Your parcel has been outside since 11am. Dory checks OpenWeatherMap every 30 minutes. Rain incoming? You get an alert with enough time to act. Nobody else does this. It will be the most-forwarded feature of the campaign.

DoryMat instantly alerts you to package theft

While other cameras react
after the fact.

Ring shows you the thief. DoryMat catches it the moment it happens — because only a mat can feel both the parcel disappearing and the absence of a footstep approaching.

DoryMat Alert — now
Package taken — no arrival detected — possible theft — camera snapshot attached.

Two mats. One complete picture.

Each mat is tuned for a different pressure signature. Together they unlock features neither can achieve alone.

Mat One · Door Mat

Dory Door Mat

Tuned for footsteps. Arrival, departure, visitor detection, and household pattern intelligence.

  • 👤
    Arrival & departure detectionTwo-step pressure sequence triggers HomeKit before you’ve even opened the door. Zero latency versus geofencing.
  • 🧳
    Visitor waiting detectionStanding still 20+ seconds with no door open = “Someone’s been at your door for a minute.” Camera pairing identifies known versus unknown visitors.
  • 🤖
    AI daily summary“Ella arrived 22 minutes early. Unknown visitor stood 90 seconds at 4pm while no one was home.” Claude synthesises the day into one paragraph every evening.
  • 📊
    Household pattern intelligenceAfter 30 days: “It’s 6:45pm. Someone usually arrives by 6:15. Home is empty — send a check-in?” Parents of teenagers pay anything for this.
Mat Two · Package Mat

Dory Package Mat

Tuned for static weight. Parcels, weather exposure, theft detection, returns workflow.

  • ⚖️
    Weight detection to ±50gFour-point load cell array. Tells you it’s a letter, a small parcel, or a large delivery — and cross-references carrier APIs to name the order.
  • 🌧️
    Weather exposure alert“Your parcel has been outside 4 hours — rain expected at 3:16pm.” Two APIs talking to each other. The most-forwarded feature of the campaign.
  • Collection confirmationWeight disappears — instant notification. Cross-referenced with door mat arrival to confirm authorised collection versus theft event.
  • 📬
    Returns workflowPlace return on mat. Dory matches your booking. “Evri collection between 9am–1pm today.” Collected: instant confirmation. End of the anxiety.

Together, they unlock what neither can do alone.

The correlation between the two mats is where the real intelligence lives.

⚠ Package weight gone · No inward footstep · 2 seconds apart → Theft alert + camera snapshot

🔐 Parcel theft detection

Package weight disappears without a corresponding inward footstep. That correlation is a theft event. Alert fires immediately. Ring shows you after. Dory catches it the moment it happens.

👤 Authorised collection

Neighbour collects whilst you’re away — door mat logs their arrival, package mat weight disappears. System knows it was intentional. Clean confirmation, no false alarm.

🔇 Smart suppression

You’re home — arrival detected. Parcel arrives 10 minutes later. No alert fires because the system knows you watched the driver leave it. Confidence beats information density.

📚 Complete entrance log

Every arrival, departure, delivery, collection, and visitor compiled into a single AI-synthesised timeline. One coherent story of your front door, every day.
