What We Deliver

End-to-end solutions from sensor to screen — designed around your site, running on your infrastructure, under your control.

Custom IoT & Sensor Networks

Remote monitoring and telemetry for sites where connectivity is limited and reliability is non-negotiable. ESP32 and LoRa-based sensor networks that feed data back to dashboards you own — your data, on your hardware.

  • Tank levels, soil moisture, temperature, and environmental monitoring
  • LoRa and low-bandwidth networks for remote and rural sites
  • ESP32-based sensor nodes with solar and battery power
  • Local gateways with on-site data storage and alerting

void loop() {
  float level = readTank();
  LoRa.send("tank_1", level);
  deepSleep(300); // 5min
}

Automation & Control Systems

Purpose-built automation for industrial, agricultural, and residential environments. Local-first control that runs on your hardware — not someone else's server. Custom logic, direct integrations with your existing equipment.

  • Pump scheduling, irrigation, and climate control based on live sensor data
  • Greenhouse, shed, and workshop automation
  • Integration with existing PLCs, relays, and equipment
  • Local control panels and dashboards — works without internet

    if moisture < config.threshold:
        await relay.activate("pump_main")
        log.info("Irrigation started")
    await sleep(60)

Surveillance & Security

Camera systems designed around your site — not generic kits off a shelf. Proper IP camera selection, wired backhaul where it matters, local NVR storage, and remote access that doesn't depend on a third-party cloud.

  • Site-specific camera placement and coverage planning
  • Local NVR with configurable retention and redundancy
  • Motion detection zones, alerting, and event-based recording
  • Secure remote access without cloud subscriptions

Network Engineering

Designed networks for homes, offices, industrial sites, sheds, and farms. WiFi site surveys, VLANs, managed switching, proper routing, and firewall rules. Not "plug in a mesh router and hope" — engineered coverage and segmentation.

  • WiFi site surveys and access point placement
  • VLANs, managed switching, and network segmentation
  • Industrial and multi-building network design
  • Firewall and routing configuration
  • Inter-building links and outdoor coverage

Web & Application Development

Custom web apps, dashboards, and management interfaces — the software layer that ties your hardware and data together. Built for performance, built to last, built to run where you want it.

  • Real-time dashboards for sensor data and system status
  • Admin interfaces and management portals
  • Progressive Web Apps that work offline
  • Mobile-responsive, accessible design

Backend Systems & APIs

Data pipelines, integrations, and backend logic designed to run on your infrastructure. RESTful APIs, database systems, and authentication — all self-contained, all under your control.

  • RESTful and GraphQL APIs for device and data integrations
  • Time-series databases for sensor and telemetry data
  • Authentication, RBAC, and audit logging
  • Runs on local servers — no mandatory cloud

async def ingest(data: SensorPayload):
    await db.insert(data)
    if data.value > threshold:
        await alert(data.device_id)
    return {"status": "ok"}

Systems Integration

Connecting the dots between equipment that was never designed to talk to each other. We integrate PLCs, sensors, databases, third-party APIs, and legacy systems into a single coherent solution — no silos, no manual data entry, no gaps.

  • Protocol translation between Modbus, MQTT, OPC-UA, REST, and more
  • Legacy equipment integration without replacing existing hardware
  • SCADA and HMI connectivity to modern web dashboards
  • Cross-system automation — one event triggers actions across multiple platforms
  • Data normalisation and centralised logging across all integrated systems

    async def poll(self):

        await self.mqtt.publish(
            "plant/status", data
        )
        await self.api.ingest(data)

Self-Hosted Infrastructure

On-premise servers, local-first architecture, and backup strategies. Cloud is an option, not a requirement. You own the hardware, the data, and the control — we handle setup, hardening, and ongoing support when you need it.

  • On-premise server setup and hardening
  • Docker-based deployments on your own hardware
  • Automated backup and disaster recovery
  • VPN and secure remote management

How We Work

01

Assess

We visit your site, understand the problem, and map out what needs solving — whether it is connectivity, monitoring, security, or control.

02

Design

A complete solution designed around your specific environment. Hardware selection, network planning, software architecture — all tailored to the site.

03

Build & Deploy

We build and install the solution end-to-end. Every component tested on-site, every integration verified, every cable labelled.

04

Handover & Support

Full documentation, training, and a system you genuinely understand. We stay available for improvements, expansions, and ongoing support — most clients keep us on for exactly that.

Got a Problem That Needs Solving?
