Dify Workflow Template Patterns for Smart Home and IoT Automation

Dify Workflow is useful for reusable smart home and IoT automation templates, but it should not replace the device control plane. This guide covers event summaries, alarm triage, human confirmation, state reconciliation, and retrieval-augmented troubleshooting.

Why TinyML on ESP32-S3 Bottlenecks on Memory, Quantization, and Real-Time Inference

ESP32-S3 can run TinyML, but production success depends less on AI instructions alone and more on SRAM, tensor arena sizing, INT8 quantization, operator support, PSRAM latency, sensor pipelines, and real-time inference budgets. This article explains the practical bottlenecks and boundaries.

AG-UI vs MCP vs Function Calling for IoT Control Interfaces

AG-UI, MCP, and Function Calling do not solve the same layer. In IoT control interfaces, AG-UI should handle user-facing agent events, MCP should govern tools and context, and Function Calling should create structured action requests inside a model call.

ESP32-S3 Voice Pipeline Design with I2S, PDM, and ESPHome Voice Assistant

ESP32-S3 voice satellites for Home Assistant and ESPHome are limited by the full audio pipeline: I2S/PDM microphones, buffers, Wi-Fi jitter, Assist pipeline latency, and TTS playback. This article explains the architecture, bottlenecks, debugging order, and boundaries.

ZHA vs Zigbee2MQTT vs Matter in Home Assistant: Which Integration Path Should You Choose?

ZHA, Zigbee2MQTT, and Matter solve different problems in Home Assistant. This guide compares device compatibility, maintenance cost, debugging depth, network boundaries, and long-term stability.

High-Density LED Control with ESP32 RMT and WLED

Driving large WS2812 or SK6812 installations with ESP32 and WLED is not just an MCU performance problem. The real constraints are LEDs per output, RMT interrupt or DMA behavior, 800 kHz serial timing, power injection, Wi-Fi load, and multi-controller sync. This article gives a practical architecture guide.

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.
