Debugging Long-Uptime ESPHome Devices on ESP32
ESPHome devices that fail after days or weeks usually suffer from accumulated system effects: heap pressure, fragmentation, Wi-Fi instability, blocking components, sen...
Building a Multi-I2C Sensor Gateway with ESP32 and ESPHome
A reliable ESP32 and ESPHome multi-I2C sensor gateway is not just about scanning sensor addresses. It needs bus isolation, warm-up windows, deep sleep trade-offs, powe...
ESP32 Energy Metering with HLW8032, BL0942, and ESPHome
ESP32 energy metering with HLW8032, BL0942, and ESPHome is not just about reading voltage, current, power, and energy. This article explains how to design the UART bou...
Why IoT Platforms Need Fleet Indexing and Device Search
If an IoT platform can only search by device name or online status, it will struggle with staged rollouts, fleet troubleshooting, and remote operations. This article e...
Choosing Open Voice Hardware for Home Assistant: Voice Preview Edition, DIY Satellites, and ESPHome Voice Nodes
Open voice in Home Assistant is not mainly a board-selection problem. It is a terminal-design problem. This article compares Voice Preview Edition, DIY satellites, and...
Best ESP32 Firmware Frameworks in 2026: How to Choose Between ESP-IDF, Arduino, ESPHome, and Zephyr
The best ESP32 firmware framework in 2026 depends less on hype and more on product lifetime, driver control, Home Assistant alignment, and platform portability. This a...
Matter vs Thread vs Zigbee in Home Assistant: What Should You Actually Choose?
Matter, Thread, and Zigbee are all relevant to Home Assistant, but they do not solve the same problem at the same layer. This article compares them from the perspectiv...
Smart Temperature Controller vs Basic Thermostat: What EchoNet-FZ5-Class Systems Actually Add
A smart temperature controller is not just a thermostat with Wi-Fi. It adds control logic, alarms, event history, remote parameter management, and fleet operations tha...
Tuya Local Control vs Cloud API vs App SDK: What Should You Choose?
Tuya projects usually fail not because one path is missing, but because local control, Cloud API, and App SDK are used in the wrong place. This article gives a product...
ESP32 Firmware Development Guide for IoT Devices
Real ESP32 firmware development is not just about connecting a device to Wi-Fi. It is about structuring BSP, drivers, protocols, config, OTA, logs, and maintenance int...
How to Model Device Online State Correctly
Device online state is not a single field. It is a derived judgment built from connectivity, heartbeat, last-seen activity, and abnormal disconnect signals such as MQT...
SGP.32 + LwM2M: A Practical Stack for Global IoT Deployment in 2026
