IoT Gateway

An IoT gateway is a hardware device that connects sensors and data loggers to the cloud, bridging local monitoring with remote access.

What is IoT Gateway?

An IoT gateway is a network device that acts as a bridge between local sensors/data loggers and the cloud. It collects data from multiple connected devices via protocols like RS485 MODBUS, Bluetooth, or WiFi, then transmits the aggregated data to a cloud platform for remote monitoring, alerting, and reporting.

Gateways are essential in large facilities where dozens of monitoring points need to feed into a single centralised dashboard. They can also interface with existing industrial equipment — such as Dixell controllers in cold rooms — without replacing legacy hardware.

Why It Matters

Many facilities already have controllers and sensors installed but lack cloud connectivity. Gateways enable digital transformation by adding real-time cloud monitoring to existing infrastructure — without costly equipment replacement. They also serve as local data aggregation points, reducing the number of individual cloud connections needed.

Frequently Asked Questions

What is the difference between a data logger and a gateway?

A data logger has its own sensor and records data directly. A gateway does not have sensors — it collects data from multiple existing sensors or controllers and forwards it to the cloud. Think of a gateway as a translator between legacy equipment and modern cloud platforms.

How many devices can a gateway connect?

IdeaBytes gateways like the IBI-CSC50T can monitor up to 20 parameters from connected Dixell controllers. RS485 MODBUS gateways can connect multiple devices on a single bus.
