Bridging legacy plants to Industry 4.0
Hexitronics Automation LLP is an Industrial IoT company based in Harihar, Karnataka. We build reliable, field-ready hardware and platforms for industry and infrastructure.
Engineers and system builders
Our team has hands-on experience deploying IoT across energy, utilities, manufacturing and public infrastructure. We design the electronics, write the firmware, build the cloud and stand behind the installation.
Most plants already have the meters, transmitters and controllers they need; the data simply never leaves the panel. Our products are built to connect that existing equipment, without replacing it.
We are trusted by PSUs and private utilities for secure, long-life IIoT architectures.

Industrial grade, without the hype
Respect what exists
We work with existing infrastructure and its constraints, not around them.
Reliability before features
Devices that keep working through power cuts, network drops and years in the field.
Built to scale
From one panel to hundreds of sites, with long-term support in mind.

Director, Hexitronics Automation LLP
“Thousands of factories in Karnataka already have the meters and sensors they need. The data just never leaves the panel. UONO changes that with one device that fits the existing panel, talks to existing equipment and stays online over WiFi or 4G. We’re proud to have built it in Karnataka, for Indian industry.”
