How to Build an IR Remote Gateway with W55MH32 for Industrial IoT and Ethernet-Based Remote Control? Summary This project uses the WIZnet W55MH32 as the main controller for an Ethernet-connected infrared gateway that can receive cloud commands, decode them into appliance control actions, and transmit IR signals to legacy devices such as air conditioners. In this design, W55MH32 is not just the network interface. It is the MCU, the Ethernet endpoint, and the protocol execution layer for MQTT-based remote control, which makes the architecture compact and appropriate for Industrial IoT…
