One platform, every industrial protocol
From the RS-485 sensor bus to the cloud broker, every Wiman gateway moves data through the protocols your plant already uses — and we are engineering the next ones now.
Protocols in every Wiman gateway
Core protocols supported on shipping firmware across the catalogue. Pick a protocol to see which products speak it and how it is implemented.
Modbus RTU
Shipping todayThe serial workhorse of industrial automation
Modbus RTU is the de-facto serial protocol for connecting energy meters, PLCs, drives, transmitters and I/O devices over RS-485.

Shipping todayModbus on the network — for PLCs, SCADA and converters
Modbus TCP wraps the familiar Modbus register model in TCP/IP, letting PLCs, SCADA systems and modern equipment exchange data over Ethernet, WiFi or 4G.

Shipping todayThe cloud transport for connected industry
MQTT is the lightweight, publish-subscribe protocol that moves device data to the cloud at scale.

We are actively engineering these — pilot units, beta firmware and early-access converters. If your project depends on any of them, our engineers want to hear about it.
BACnet / IP
In engineeringThe protocol of building automation and BMS
BACnet / IP is the standard for building management systems — HVAC, lighting, energy meters, access control.

In engineeringThe metering bus for water, gas, heat and electricity
M-Bus is the European standard for reading utility meters — water, gas, heat and electricity — over a robust two-wire field bus.
Read engineering briefWhat is next on the roadmap
Beyond the protocols above, our protocol pipeline includes BACnet MS/TP, OPC-UA, KNX and LoRaWAN. Engineering samples and proof-of-concept firmware available on request — pencilled in to ship across 2026 and into 2027.
Need a protocol we don't list yet?
We design our boards, write our firmware and own our protocol stack — so adding support for the protocol your project needs is an engineering decision, not a sourcing one.
