Para el env\u00edo de los mensajes hacia el broker MQTT y Home Assistant se usa un dispositivo configurado como gateway.<\/p>\n

Se usa un dispositivo en lugar de un concentrador en la etapa de prototipo considerando los costos involucrados. La pr\u00f3xima tarea es desarrollar el gateway usando un concentrador, cuyo valor es\u00a0 m\u00e1s alto.<\/p>\n
