An IoT manufacturer, engineered in India
Wiman designs and manufactures industrial-grade IoT gateways, Modbus I/O devices and protocol converters — engineered in India for high reliability, long-term operation and seamless integration into industrial environments.
We make industrial data move — reliably
Across factories, utilities and infrastructure, the hardest part of IoT is rarely the dashboard. It's getting trustworthy data off the equipment and into the cloud, and keeping it flowing for years in tough conditions.
That is the problem Wiman is built to solve. We design and manufacture the gateways, I/O and converters that bridge field devices and modern platforms — so system integrators, automation engineers and plant owners can build on a dependable foundation.
IoT hardware, engineered & manufactured in Chennai, India
A manufacturer, not a reseller
We control every layer of the product — which is why we can stand behind its reliability and tailor it when you need something specific.
Hardware design
We design the boards in-house — from the cellular front-end to the RS485 isolation and rugged power stage.
Firmware & protocol
We write the firmware and own the Modbus-to-cloud protocol family, so behaviour is consistent and documented.
Manufacturing
Built and tested in Chennai, with the control that local manufacturing gives over quality and lead time.
Support & customisation
Support comes straight from the people who made the product — and we customise when a project needs it.
How we build
Reliability first
Devices are meant to be installed and forgotten. Wide-range power, watchdogs and store-and-forward are standard, not extras.
Open & interoperable
Standard Modbus in, standard MQTT/HTTP out. Your data is never locked to a single dashboard.
Engineered, not assembled
Real engineering behind every model — measured, tested and documented, not white-labelled.
Let's build something dependable
Whether it's a single gateway or a fleet across sites, we'd like to understand what you're connecting.
