How to Design a Local-First Smart Home with Home Assistant

A local-first Home Assistant architecture is not the same as trying to remove every cloud service. The stronger pattern is to keep device control, critical automations, state coordination, and recovery paths local while treating cloud services as optional enhancement layers.

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.
