所以我在最近购买了一个 Arduino Yun 之后使用了 Temboo，但是我在通过组合 Choreos 获取和发布数据时遇到了问题。
我正在使用 Yahoo GetWeatherByAddress Choreo 并尝试将我想要的单个值发布到 Xively Feed。我正在使用 Xively Write Choreo 并以 JSON 格式输入 FeedData。
到目前为止，我在一次发布 2 个值（湿度和压力）方面取得了一些成功。不幸的是，我想使用的不仅仅是这个，还有湿度、温度、天气条件（公平、有风等）和面包板上的 LDR 读数。所以它每 10 秒循环一次，读取所有这些值，然后将它们发布到 Xively。如果未注释的温度值超过温度值，则温度值似乎甚至无法打印到串行监视器。它也没有完成整个过程（成功返回 Http 200）它发布值，然后直接“等待”下一组要检索的值。我在哪里错了？
