ESP32 S3 Smart Home Assistant Voice: Open source software with ESPHome firmware
This smart home assistant is for the tech-savvy homeowner who wants privacy-focused voice control without corporate surveillance. While many devices prioritize convenience, this one offers true integration with your existing Home Assistant setup.
You get advanced voice recognition that actually works in a busy household. The dual microphones with noise filtering pick up your commands clearly even when the TV is on in the background. The multicolored LED ring gives you instant visual feedback without needing to check your phone.
Connect it to your 2.4 GHz Wi-Fi network and use the physical rotary dial to adjust volume or LED brightness. The compact design blends into any room, and the open source software means you control your data. This isn't just another Alexa compatible device—it's a tool that respects your privacy while making your smart home more responsive.
