Building an ESP32 Modbus-RTU bridge is not mainly about connecting a MAX485 board. The real issues are RS485 electrical design, UART ownership, polling cadence, and the operational boundaries of ESPHome modbus_controller. This article explains how to bridge PLC data into ESPHome and Home Assistant more reliably.
