所以我已经研究同一个问题大约一年了。我很快就让它在我的 Mac 上运行，但在我的 PC 上正常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 地址发生变化，因为它们是动态的（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。对以下代码有任何疑问，请告诉我。
# 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}
}
和
