Everything you need to manage smart locks

A complete IoT platform for monitoring, controlling, and analyzing your entire fleet of HHD smart electronic locks.

Real-Time Tracking

Live GPS location tracking with full route history. See exactly where every lock is at any moment on an interactive map.

Geofence Alerts

Draw custom geofence boundaries and receive instant alerts when a device enters or exits a zone. Protect high-value assets.

Alarm Monitoring

Tamper detection, illegal open alerts, low battery warnings, and vibration alarms — all in real time with configurable thresholds.

Remote Commands

Lock, unlock, query status, and configure device parameters remotely. Send commands individually or in bulk to your fleet.

Reports & Analytics

Generate detailed reports on device usage, events, battery life trends, and movement patterns. Schedule automatic exports.

Kafka Streaming

High-throughput event ingestion via Apache Kafka. Process thousands of device events per second with guaranteed delivery.

How It Works

From device to dashboard in seconds

Our platform seamlessly connects your HHD smart locks to a powerful management console.

1

Provision Devices

Register your HHD smart locks on the platform with IMEI and assign them to zones or assets.

2

Stream Events

Devices report location, status, alarms, and NFC events in real time via Kafka messaging.

3

Monitor & Control

View live dashboards, send remote commands, and configure geofence rules from the web console.

4

Analyze & Report

Generate automated reports, track trends, and export data for compliance and operational insights.

Built for integration

A fully documented REST API, real-time Kafka streams, and webhook support make it easy to embed smart lock data into your own applications and workflows.

Example endpoint REST 
GET /api/v1/devices
  ?status=online
  &limit=50

// Response
{
  "data": [
    {
      "id": "HHD-GL300-1042",
      "status": "online",
      "lat": 31.2304,
      "lng": 121.4737,
      "battery": 92,
      "sealed": true
    }
  ],
  "total": 1247
}
REST API
Authenticate with OAuth 2.0. Query devices, send commands, manage geofences, and pull event history — all programmatically.
Real-Time Streaming
Subscribe to Kafka topics for instant device events. Process lock/unlock, alarms, GPS updates, and NFC seal data at scale.
Webhooks
Push alarm and event notifications directly to your system. Configure per-event HTTP callbacks with retry logic.
