我需要有关Node Red（在Raspberry Pi上）的增量的帮助。我正在尝试制作一个带有LCD触摸屏和用于远程访问的应用程序的智能恒温器（例如，在一个寒冷的冬天回家，想开始为您的公寓供暖）。 我们将不胜感激有关如何通过android（不是本地网络）通过Internet（而不是本地网络）连接到Raspberry Pi的一些建议以及教程或示例中的链接。
P.S。我正在为一个朋友做这个，我向他保证会取得好成绩。 抱歉，代码混乱... =>在编辑中将其清除
由于我对NodeRed和JS的经验不足，我已经尽一切努力使代码正常工作。
全局变量可能就可以解决问题...我还没有弄清楚...
我遇到的另一个障碍是能否访问本地网络之外的代码并与之交互。

旧的恒温器基本上是一个自动继电器开关。我必须使其聪明，最好的选择是覆盆子pi。
增量部分可以代替滑块（我有备份），并且必须由仪表板UI中的按钮触发。
我提到的除 以外的所有内容 正确 。
谢谢您的帮助！（或至少是您的时间）
