Edge AI Device OTA: How to Do Staged Rollouts and Rollbacks

The hard part of Edge AI OTA is not pushing a new package. It is designing staged rollout, rollback, and remote recovery for devices whose firmware, model, and configuration evolve together. This article explains how to do it from ESP32 to RK3566.

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.
