Use o mecanismo de AWS IoT Core regras para AWS IoT Events

As regras a seguir republicam AWS IoT Core MQTT mensagens como mensagens de solicitação de atualização paralela. Assumimos que AWS IoT Core as coisas são definidas para uma unidade de aquecimento e uma unidade de resfriamento para cada área controlada pelo modelo do detector. Neste exemplo, definimos coisas chamadas "Area51HeatingUnit" e "Area51CoolingUnit".
