Edge Gateway vs IoT Platform vs Serial Converter

Edge gateway vs IoT platform vs serial converter: learn how each layer works in device connectivity projects, when to use each one, how to combine them, and when not to overbuild.

OPC UA vs Modbus vs BACnet: How to Choose for Industrial and Building Automation

OPC UA, Modbus, and BACnet should not be compared only by which protocol is newer. Modbus fits low-level device register access, BACnet fits building automation interoperability, and OPC UA fits industrial semantic modeling, edge aggregation, and cross-system object views.

Why Edge AI Fails More Often on Observability Than on Model Accuracy

Edge AI deployments rarely fail first on model accuracy. They fail when teams cannot see input health, inference health, version context, or diagnostic evidence. This article explains why observability should be designed as a core Edge AI capability from ESP32-class devices to Linux edge boxes.

Brownfield to Cloud: A Practical Path for Legacy Industrial Equipment

Legacy industrial equipment projects usually fail when teams push PLCs, meters, and serial devices straight into the cloud without a stable edge boundary. This article outlines a safer brownfield-to-cloud path built around asset inventory, edge normalization, reliable uplink, and controlled write-back.

Why Industrial Edge Gateways Need Store-and-Forward

Industrial edge gateways that only forward data usually lose control of buffering, replay order, duplicate writes, and acknowledgment recovery during weak network conditions. This article shows how a practical store-and-forward design should work.

Designing a Protocol Adapter Layer for Industrial IoT

Industrial IoT platforms that treat Modbus, OPC UA, MQTT, and HTTP as isolated drivers usually lose control of semantic mapping, error handling, command confirmation, and data quality. This article outlines a safer protocol adapter layer design.

How to Layer OPC UA, MQTT, and Modbus in Industrial IoT

OPC UA, MQTT, and Modbus are not simple replacements for one another in industrial IoT. In many practical architectures, Modbus stays at device access, OPC UA unifies edge semantics, and MQTT carries northbound events and decoupled platform integration.

ESP32 Modbus RTU Bridge for ESPHome and Home Assistant

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.
