Connected Systems Engineering

From Physical Equipment to Operational Action

Connect equipment, edge devices and software so teams can observe events, retain history and act on defined conditions.

IoT architecture depends on the equipment, site, network and consequence of failure. Rodent designs the path from a physical signal to an operator decision, including what should happen when connectivity or downstream services are unavailable.

What we deliver

Engineering capability, connected to the operation.

Each engagement is scoped around the workflow and evidence available—not a fixed package of unnecessary features.

Sensor Integration

Capture relevant readings and equipment state through supported interfaces.

Edge Devices

Local collection, validation or control close to the equipment.

Telemetry Transport

MQTT or another appropriate protocol for reliable device communication.

Ingestion & Processing

Receive, normalise and route device events into software services.

Rules & Alerts

Evaluate defined conditions and notify the appropriate operational workflow.

Monitoring Dashboards

Current equipment state, incidents and operational context.

Historical Data

Time-ordered readings and events for review and investigation.

Fleet Considerations

Device identity, configuration and maintainable communication boundaries.

How the system works

A clear path through the system.

This reference flow shows the responsibilities that must connect. The final architecture depends on the project’s security, data, infrastructure and operational constraints.

Integration

Designed around real system boundaries.

ESP32-class edge hardware, MQTT and API-connected backends are relevant where project conditions support them. Protocol, storage and connectivity choices remain project-specific.

Delivery method

From operational discovery to a maintainable release.

  1. 01

    Discovery

    Understand the operation, users, constraints and definition of success.

  2. 02

    Site & Signal Survey

    Map equipment, readings, connectivity, power and failure conditions.

  3. 03

    Prototype

    Validate sensors, edge hardware and communication before scale decisions.

  4. 04

    Architecture

    Define system boundaries, data models, interfaces and deployment choices.

  5. 05

    Hardware Validation

    Test the chosen device and integration under representative conditions.

  6. 06

    Engineering

    Build in reviewable increments, keeping the working system visible.

  7. 07

    Testing

    Verify core workflows, edge cases, security boundaries and operational behaviour.

  8. 08

    Deployment

    Prepare environments, releases, documentation and operational handover.

Business outcomes

Technology in service of better operations.

Equipment visibility

Turn physical state into information operators can inspect.

Earlier awareness

Route defined events and thresholds into an alert workflow.

Operational history

Retain readings and incidents for investigation and improvement.

Connected decisions

Share validated device data with dashboards and approved business systems.

Who it is for

Relevant operating contexts.

Fit is established in discovery; this service is not presented as equally appropriate for every organisation.

  • Industrial and energy operations
  • Distributed equipment operators
  • Facilities and infrastructure teams
  • Engineering teams validating a connected product

Practical questions

Before an engagement starts.

Does every project use MQTT?

No. Protocol selection depends on device support, connectivity, message patterns and operating constraints.

Can you start with a prototype?

Yes. A bounded prototype is often the safest way to validate sensing, communication and operator value.

Start the conversation

Need visibility into equipment, sensors or field operations?

Bring the current process, constraints and intended users. Rodent will help define a credible next engineering step.
