Accuenergy, distributed by Netonomy Australia, has released the AcuHMI, a touchscreen human-machine interface (HMI) and multi-protocol gateway to simplify data integration, real-time monitoring and control across data centre PDUs, industrial automation, energy management and building automation systems.

The AcuHMI combines a 7” capacitive touchscreen display with an integrated gateway and data concentrator, addressing interoperability challenges in facilities that rely on multiple meters, sensors, controllers and power distribution units operating across different communication protocols.

“Many facilities still depend on separate devices for protocol translation, monitoring and data logging. With the AcuHMI, operators gain a single platform that reduces system complexity, eliminates redundant hardware and improves overall connectivity,” Accuenergy product manager Ryan Manbahal says.

As power density continues to increase, particularly in data centres supporting AI workloads, operators are seeking unified visibility across electrical infrastructure. In many environments, rack-level PDUs and monitoring devices use different protocols, requiring multiple gateways and interfaces that increase cost and maintenance overhead.

The AcuHMI is designed to consolidate these functions into a single platform, enabling operators to visualise load distribution, track energy usage and manage interoperability across large-scale deployments without relying on multiple external gateways.

The device supports Modbus, BACnet, MQTT and SNMP, allowing it to serve as a central gateway between metres, PDUs and controllers while enabling cloud connectivity. Dual Ethernet ports with RSTP support and dual RS485 ports allow daisy-chain networking and are intended to reduce wiring complexity in data centres, manufacturing facilities and building automation systems.

For data logging, the AcuHMI includes 32GB of onboard memory and supports automatic data transfer via HTTP, HTTPS, FTP or SFTP, with export in CSV or JSON formats. A built-in web server provides remote access for configuration and real-time visualisation, while alarm functions with threshold, hysteresis and event logging support proactive maintenance strategies.

The AcuHMI aims to bridge operational technology and information technology, providing a foundation for edge applications and deeper system integration across industrial IoT, energy management and intelligent building environments.
