Meet the New Intesis MQTT Gateway for the 700 Series Air

In today’s connected buildings, the ability to seamlessly exchange data between HVAC systems and control platforms isn’t just a nice-to-have, it’s expected. That’s why the latest addition to the Intesis portfolio, the new MQTT gateway for the 700 Series Air, is such a big deal for automation professionals, integrators and building system designers.
 
This gateway brings cloud-ready MQTT connectivity to multi-indoor HVAC systems, unlocking flexible, efficient and future-ready integration into modern building management workflows.

Why MQTT Matters for HVAC Integration

MQTT (Message Queuing Telemetry Transport) has become the de-facto standard for lightweight, efficient messaging in IoT ecosystems. It uses a publish/subscribe architecture that reduces network overhead and enables quick, secure information exchange, even across unreliable connections.
For HVAC systems, this translates into:

• Real-time bidirectional data flows between equipment and control platforms.
• Low-overhead, scalable communication ideal for large systems.
• Better visibility and control by making HVAC telemetry available to cloud or local brokers.

This makes MQTT uniquely suited to modern smart buildings where data-driven decision making and centralised control are essential.

Introducing the New MQTT Gateway on 700 Series Air

The 700 Series Air platform from Intesis is a versatile gateway series designed to unify HVAC integrations across multiple protocols. The latest MQTT gateway extends this capability with powerful features:
 

Native MQTT Support

• Supports MQTT 3.1.1, compatible with any standard MQTT broker, whether on-premise or cloud-based.
• Publisher/subscriber model enables true bidirectional messaging for control and telemetry.

Built-In Security & Certificate Management

• Secure TLS connections ensure encrypted MQTT traffic.
• Certificates can be managed and renewed remotely, reducing onsite maintenance overhead.

Unified Variable Mapping

• HVAC variables are standardised across brands and models.
• This simplifies integration into higher-level platforms, eliminating bespoke variable mapping for each vendor.

Broad HVAC Compatibility

• Works with the most commonly deployed air conditioner and heat pump systems.
• Ideal for multi-brand, multi-indoor installations.

What This Means for Your Projects

Here are the practical advantages this gateway brings to building automation and controls professionals:
 

Cloud-Ready Architecture

By leveraging MQTT, HVAC systems can easily be connected to IoT platforms, dashboards and analytics engines, without heavyweight middleware. This opens doors for predictive maintenance, optimisation and integration with enterprise systems.

Scalability & Flexibility

A single 700 Series Air gateway can manage multiple indoor units, reducing hardware complexity and configuration effort across large buildings or multi-zone installations.

Works With Existing BMS/BAS

In addition to MQTT, the 700 Series Air supports other industry standards such as BACnet, Modbus and KNX, making it a flexible bridge between HVAC equipment and existing building systems.

Typical Use Cases

Here are some real-world scenarios where the MQTT gateway adds value:

• Centralised HVAC dashboards that display live data and status via an MQTT broker.
• Automated control logic driven by external analytics or optimisation engines.
• Integration of disparate HVAC brands into a single control fabric.
• Energy performance monitoring and reporting across portfolios.

Configuration & Tools

To simplify setup and commissioning, you can use Intesis MAPS, the intuitive configuration tool that:

• Detects connected HVAC units automatically.
• Maps variables and data points consistently.
• Helps manage certificates for secure MQTT connections.

Plus, if you need to confirm compatibility between a specific HVAC model and the right gateway, Intesis provides a compatibility tool that helps you choose the correct hardware quickly, especially useful for complex multi-brand projects.
