I Pointed My Industrial IoT Platform at My Dog — Here Is What Happened

DEV Weekend Challenge: Dog Days Edition Submission 🐕

I Pointed My Industrial IoT Platform at My Dog — Here's What Happened

Dog Days Challenge Entry 🐶


My company builds industrial IoT infrastructure — 928 gateways monitoring oil wells, UAV testing lines producing 60 drones a day, maritime safety platforms with 99.9999% uptime.

This weekend, I pointed that entire stack at a Golden Retriever.


The Stack

Meet PawTrack — a dog health monitoring demo built on DGIOT, our open-source industrial IoT platform:

Smart Collar (PawCollar-V2)
    │  MQTT · 2-second sampling
    ▼
DGIOT Platform (Erlang/OTP)
    │  300+ protocol adapters · Shadow devices · Rule engine
    ├── TDengine (time-series storage)
    ├── DLAS Ontology Engine (OWL reasoning)
    └── Dashboard (real-time vitals)
Enter fullscreen mode Exit fullscreen mode

The collar streams four metrics every 2 seconds:

  • Heart rate (bpm)
  • Body temperature (°C)
  • Activity level (%)
  • Battery + RSSI

Why Industrial IoT Makes Sense for Pets

Here's the part that surprised me: a dog is just another telemetry source.

The industrial world has spent decades solving problems that pet tech startups are rediscovering:

Industrial Problem Pet Equivalent
Gateway goes offline in a remote oil field Dog runs out of Wi-Fi range
Sensor drift on a pressure gauge Collar temperature calibration
False alarms flooding operators "Your dog is dying" notification at 3am
928 gateways to manage Multiple pets, multiple collars

We already solved all of these for oil fields. A Golden Retriever is just a smaller, fluffier oil well.

The Ontology Layer — Why It Matters

The interesting part is our DLAS ontology engine. Instead of hard-coded thresholds ("if temp > 39.5, alert"), we model knowledge:

GoldenRetriever  Dog  hasRisk.HipDysplasia
ActivityDrop(dog, 40%)  BreedRisk(dog, High)  Alert(medium)
Enter fullscreen mode Exit fullscreen mode

This means the system knows that a Golden Retriever's activity drop is more concerning than a Border Collie's — hip dysplasia is breed-specific. The ontology compiles to Erlang pattern matches, so reasoning happens at runtime speed.

The Shadow Device

Every physical device gets a digital twin — a gen_statem process that mirrors its lifecycle:

init → auth → online → {active, inactive, alert}
Enter fullscreen mode Exit fullscreen mode

When the collar drops offline, the shadow holds state and retries silently. The dashboard doesn't scream "DOG IS GONE" — it waits, because shadows absorb network chaos. This is the same mechanism that keeps oil field gateways calm during sandstorms.

The Demo

The live demo simulates the MQTT stream with real-time vitals, ontology inference, and the alert closed-loop (discover → confirm → handle → verify):

dgiot/pets/wanCai/telemetry  {"temp":38.6,"hr":88,"activity":62}
dgiot/pets/wanCai/shadow  {"state":"active","battery":87,"rssi":-62}
Enter fullscreen mode Exit fullscreen mode

Watch for the activity-drop alert — when activity falls below 35%, the ontology fires a hip dysplasia risk warning for the Golden Retriever, generates a work order, and closes the loop when activity recovers.

What's Real vs. What's Demo

Real: DGIOT platform, DLAS ontology engine, shadow device architecture, MQTT pipeline, alert closed-loop — all production code from our industrial deployments.

Demo: The collar hardware (simulated), the dog (borrowed), the vitals (synthetic values).

The point: the platform is production-grade. Building pet monitoring on it took one afternoon, because the hard parts — protocol handling, shadow state, ontology reasoning — were already done for 300+ industrial use cases.

The Code

  • Platform: github.com/dgiot/dgiot — Apache 2.0, 4.8K stars
  • Demo: Single HTML file simulating the MQTT stream

Want to build your own? The platform deploys in 6 minutes:

git clone https://github.com/dgiot/dgiot.git
cd dgiot && docker-compose up -d
Enter fullscreen mode Exit fullscreen mode

Built for the Dev.to Dog Days Challenge. If your dog's activity drops below 35%, take them to the vet — the ontology says so.
