Your Network Control Starts Here 

Unlock seamless integration across your entire IoT ecosystem with a toolset built for flexibility. RutOS API empowers you to shape your network the way your applications demand. 

What is RutOS API? 

RutOS API is a programmable interface that enables both external applications and internal scripts to interact directly with Teltonika IoT devices.

Designed with flexibility in mind, it allows developers to work with familiar automation tools such as Node-RED or programming languages like Python or Bash, making integration straightforward and efficient.  

It provides programmatic access to data monitoring and network control, forming the foundation for process automation and seamless integration with third-party platforms. It supports local and remote operation – from on-device scripts to management software and cloud services – so developers can unify device control across any deployment. 

How does it work? 

In essence, RutOS API enables seamless M2M communication, allowing developers to automate operational workflows and integrate networking devices into broader IoT systems. For example, an industrial controller can detect a change in production status and automatically adjust network configurations through the API, ensuring consistent performance without manual intervention. In practice, the interface uses familiar HTTP methods – GET, POST, PUT, DELETE – with JSON. 

Because the same interface operates internally and externally, it delivers real-time control and scalable rollout. Beyond device-level control, the API integrates with platforms such as our Remote Management System (RMS), Microsoft Azure, and AWS for centralized monitoring and configuration.  

A Framework for Customization 

Comprehensive developer documentation is at the heart of the best RutOS API experience!

For projects that require custom firmware scenarios, the RutOS API provides a reliable framework for extending and adapting Teltonika IoT devices. Instead of relying on reverse engineering or complex system modifications, developers can use the official documentation and available endpoints to implement tailored logic, automation, or integration features directly within their firmware. 

The Getting Started section introduces the basics and first configuration steps, while Fundamentals, Examples, and Tutorials help you understand core concepts and apply them in real scenarios. A detailed Reference section then allows developers to select their specific Teltonika IoT device and explore categorized API endpoints – such as Authentication, Interfaces, Modbus, VPN, or SIM card management – to implement exactly the functionality they need.

This approach provides system integrators and IoT developers a flexible foundation for building efficient, industry-specific applications without compromising stability or support. 

Endless opportunities: real-life examples 

Built for adaptability, the RutOS API is used across diverse environments to unify devices, automate workflows, and share data between systems. Discover how its flexibility comes to life in real-world applications below! 

Industrial monitoring & automation 

In industrial environments, the RutOS API can act as a bridge between production equipment and supervisory systems. By communicating with PLCs, sensors, or Modbus-enabled controllers, it allows centralized data collection and status reporting.

Metrics such as temperature, pressure, or machine uptime can be shared with SCADA or cloud platforms for trend analysis and predictive maintenance. 

Through such integrations, operators can detect irregularities early, reduce downtime, and improve overall equipment efficiency of their industrial and automation IoT solutions. 

Fleet management applications  

In transportation applications such as fleet management, the RutOS API enables complete visibility and remote control over Teltonika routers installed in vehicles including delivery vans, buses, and emergency units. Through automated data exchange, it can retrieve GPS coordinates, ignition status, or Wi-Fi client lists and forward them to platforms like Azure IoT Hub for centralized monitoring. 

Operators can configure automated alerts when vehicles enter specific zones or initiate remote diagnostics to assess signal strength and device status, helping maintain safe, efficient, and well-connected fleet operations. 

Smart city & energy

The same interface can integrate with HVAC systems, power meters, and other automation equipment to support monitoring, remote control, and data exchange.

By using Teltonika RutOS API, your IoT devices can report environmental and operational parameters to higher-level systems, which can then adjust lighting, ventilation, or energy usage dynamically. 

Cloud integration allows for intelligent scheduling and optimization, while security or maintenance teams can receive status updates or alerts during emergencies. This unified approach enhances situational awareness, reduces energy consumption, and simplifies remote management in smart city solutions. 

Unlock New Possibilities Today 

With RutOS API, you can create efficient, automated custom firmware scenarios tailored to your needs – whether you’re managing vehicle fleets, optimizing energy use, integrating industrial systems, or developing something entirely unique.
