Built for industrial demands
Reliable connectivity for machines, meters and sensors
Get an industrial router or IoT gateway that does not lock your data behind a closed vendor cloud. Melqart supplies and programs open-Linux gateways that connect real equipment to the IT systems you already run.
Cellular, Ethernet, GNSS and field interfaces for remote industrial sites.
Rugged gateway hardware suited to vehicles, assets, buildings and plants.
Open configuration, documented software and a transferable edge stack.
Router or gateway
Choose the role your deployment needs
Use an industrial router when secure network connectivity and failover are the main requirement. Use an IoT edge gateway when the device also needs to translate protocols, buffer data and run local logic.
Industrial routers for cellular failover, VPN access and site connectivity.
IoT gateways for Modbus-to-MQTT, OPC-UA, buffering and edge processing.
Edge computers for heavier workloads, analytics and containerized services.
Protocols
From Modbus to MQTT without proprietary lock-in
Melqart configures the full data path from fieldbus and machine networks to your cloud, ERP, CMMS, EAM or analytics platform.
Modbus RTU/TCP, OPC-UA, MQTT(S), BACnet and serial RS-485/RS-232.
Data normalization, store-and-forward buffering and managed updates.
Auditable implementation that can be extended or handed over.
Field use
Crane connectivity and retrofit projects
For mixed mobile fleets, open gateways can collect load, tilt, runtime and location data without forcing the operator into one closed equipment platform.
Retrofit telemetry on existing machines and vehicles.
Normalize signals across mixed equipment generations.
Send clean data to the systems your teams already use.

FAQ
— 01What is an IoT gateway?
An IoT gateway connects machines, sensors or controllers to an IT platform. It often translates industrial protocols, buffers data and runs edge logic before data reaches the cloud.
— 02What is the difference between a router and an IoT gateway?
A router focuses on network connectivity and routing. An IoT gateway usually adds protocol conversion, local processing, application logic and device management.
— 03Can Melqart program the gateway software?
Yes. Melqart supplies and programs open-Linux gateways, including protocol integration, edge services, cloud connectors and managed update workflows.
