The ESP32 project I'm most proud of has no cloud, no app, and no gimmicks

A hobbyist shares their experience building a Bluetooth proxy using an ESP32 board and ESPHome, which connects Bluetooth devices to Home Assistant without any cloud, app, or complex configuration. The project took only ten minutes from firmware flashing to working integration, and despite being simpler than other builds, it proved more impactful by bringing smartwatches, earphones, and sensors into the smart home ecosystem. The key takeaway is that minimal, reliable builds often deliver more value than technically complex ones.
