Gateway ChirpStack<\/h2>\n

La funci\u00f3n Encode se encarga de preparar los valores para ser enviados por la red LoRaWan. El ejemplo muestra el uso de las variables estado y duraci\u00f3n:<\/p>\n

\/\/ Encode encodes the given object into an array of bytes.\r\n\/\/  - fPort contains the LoRaWAN fPort number\r\n\/\/  - obj is an object, e.g. {\"temperature\": 22.5}\r\n\/\/  - variables contains the device variables e.g. {\"calibration\": \"3.5\"} (both the key \/ value are of type string)\r\n\/\/ The function must return an array of bytes, e.g. [225, 230, 255, 0]\r\nfunction Encode(fPort, obj, variables) {\r\n  var estado = obj[\"estado\"];\r\n  var duracion = obj[\"duracion\"];\r\n  var mensaje = [50,20];\r\n  if (estado == \"ON\") {\r\n  \tmensaje = [49,duracion];\r\n  }\r\n  if (estado == \"OFF\") {\r\n  \tmensaje = [50,20];\r\n  }\r\n  return mensaje;\r\n}\r\n<\/pre>\n
Mensaje MQTT<\/p>\n
El mensaje Mqtt que activa la instrucci\u00f3n tiene un formato que requiere para el tema o t\u00f3pico: identificador de aplicaci\u00f3n del ChirpStack, deviceEUI,<\/p>\n
el mensaje contiene si se confirma la trama, el puerto de la aplicaci\u00f3n y un diccionario \"object\" con las variables\u00a0 sus valores correspondientes en texto o num\u00e9rico.<\/p>\n
El ejemplo de la instruccion para el dispositivo es:<\/p>\n
mosquitto_pub -h \"localhost\" -u \"usuarioprueba\" -P \"usuarioclave\" -t \"application\/3\/device\/bc55318912bfd090\/command\/down\" -m '{\"confirmed\":true,\"fPort\":3,\"object\":{\"estado\":\"ON\",\"duracion\":46}}'<\/pre>\n
Para observar el estado en mqtt para probar el envio del mensase se\u00a0 usa la instrucci\u00f3n de suscripci\u00f3n:<\/p>\n
mosquitto_sub -h \"localhost\" -u \"usuarioprueba\" -P \"usuarioclave\" -t \"application\/3\/device\/bc55318912bfd090\/command\/down\"<\/pre>\n
Home Assitant - configuraci\u00f3n<\/h2>\n
Se realiza combinando una variable num\u00e9rica (input_number) para la duraci\u00f3n en segundos, y se env\u00eda como una instrucci\u00f3n de control usando una plantilla de foco dim (light).<\/p>\n
