Aún no he podido usarlo. Actualicé los controladores de la placa y compilé el software en ESPHOME. Lo integré en Home Assistant, pero al usar TTS, la voz sale arrastrada, como si estuviera a una velocidad de 0.2X. Al reproducir otros sonidos y medios, ocurre lo mismo. Seguí 2 tutoriales diferentes con el mismo resultado. También probé usar Nabu Casa y se mantuvo igual. Dediciaré más tiempo probando otros firmwares antes de concluir que la placa tiene un defecto, y luego la devolveré. Si obtengo otro resultado, cambiaré la evaluación aquí.





De acuerdo
El micrófono no es tan sensible como esperaba, pero en general es un buen producto.
Muy bien empaquetado, todo está perfecto.
Tal como se describe, muy bueno.
