根据错误信息，你在代码中使用了未声明的变量`data`，并且编译器建议你是否指的是`std::data`。为了解决这个问题，你需要在适当的位置声明并初始化`data`变量。

以下是一个示例，假设你要将温度数据存储在`data`变量中：

void mqttIntervalPost() {
  int data = getTemperature(); // 假设这是获取温度数据的函数
  char param[50];
  sprintf(param, "{\"CurrentTemperature\":%d}", data);
  // 其他的代码逻辑...
}

请注意，这只是一个示例，你需要根据你的实际情况修改代码中的`getTemperature()`函数和数据类型。

如果问题仍然存在或者你需要更多帮助，请提供完整的代码以便更详细地分析和解决问题。
