ESPHome vs OpenMQTTGateway for ESP32 Bridge Devices

ESPHome is usually the better fit for declarative ESP32 device nodes, sensors, relays, and Home Assistant native integration. OpenMQTTGateway is a better fit for BLE, 433 MHz, IR, and other passive signals that should be collected into MQTT. This article compares the control model, protocol coverage, maintenance cost, and limits.

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.
