所以我已经在同一个问题上工作了大约一年。我很快就让它在我的 mac 上运行，但在我的 PC 上运行时遇到了很多麻烦。我尝试了许多不同的方法。我有一个家庭自动化系统，当我或我的伴侣在家时（即我们的 iPhone 可以在家庭 WiFi 上检测到），它会打开暖气和热水（通过 arduino 和 RF 模块）。最后，我使用“nslookup”来查找 iPhone 的 IP 地址（以防 IP 地址因为它们是动态的而发生变化（但它们实际上从未在我的路由器上这样做））和“nmap”来检测 iPhone 是否开启网络。如果 iPhone 处于深度睡眠状态，'nmap' 并不总是能找到手机，所以在它说手机在家之前，我已经让它检查了 10 次。下面是我在 python 中的家庭自动化代码的一部分。我用过线程。
# Dictionary to store variables to reuse on program restart
v = {
'boilerControlCH' : 'HIH', # 'scheduled' or 'HIH' (Honey I'm Home)
'boilerControlHW' : 'scheduled',
'thermostatSetPoint' : 20.8,
'thermostatVariance' : 0.1,
'morningTime' : datetime(1970,1,1,6,0,0),
'nightTime' : datetime(1970,1,1,23,0,0),
'someOneHome' : False,
'guest' : False,
'minimumTemperatureOO' : False,
'minimumTemperature' : 4.0,
'iPhoneMark' : {'iPhoneHostname' : 'marks-iphone', 'home' : False},
'iPhoneJessica' : {'iPhoneHostname' :'jessicaesiphone', 'home' : False}
}

如果您将代码直接复制到自己的脚本中，则代码可能无法正常工作，因为缺少一些我没有复制的部分，以尝试保持简单易读，但希望上面的代码能让每个人都了解我是如何做到的做了事情。
