【工具】【HA智能家居】主人回家自动开灯,离家自动关灯
前提环境:
安装有home assistant(以下简称ha)
安装有mosquitto (mqtt服务端)
有ha可控制的灯
原理:
监视光猫管理页面的无线终端设备列表,存在指定mac设备即被认定为主人回家,否则被认定为离家。

win.loopMessage();MQTT协议其实也是建立在tcp协议上的,理论上来说只要支持MQTT协议的设备都可以进行跨平台通讯。
我用Golang实现了一下,感觉挺好玩的。
我想到一个使用场景,就是家里的电热水器。平时上班的时候电热水器可以关掉,而回家的时候电热水器自动启动,这样比较省电。我经常是忘记回家去开电热水器,等想洗澡的时候又要等很长时间。

好久没登录了,上来填坑,一楼的办法非常不好,
后来在GitHub上找到一个更好的办法.(详细请访问https://github.com/brannondorsey/sniff-probes),基于此方案修改一下:
sniff-probes-mod.sh
#!/bin/bash
OUTPUT="${OUTPUT:-probes.txt}"
CHANNEL_HOP="${CHANNEL_HOP:-0}"
# channel hop every 2 seconds
channel_hop() {

IEEE80211a="36 40 44 48 52 56 60 64 149 153 157 161"
IEEE80211bga="$IEEE80211bg $IEEE80211a"
IEEE80211bga_intl="$IEEE80211bg_intl $IEEE80211a"
while true ; do
for CHAN in $IEEE80211bg ; do
# echo "switching $IFACE to channel $CHAN"
iwconfig $IFACE channel $CHAN
sleep 2
done
done
}
if ! [ -x "$(command -v gawk)" ]; then
echo 'gawk (GNU awk) is not installed. Please install gawk.' >&2
exit 1
fi
if [ -z "$IFACE" ] ; then
echo "IFACE env variable must be set. Type \"ifconfig\" to view network interaces."
exit 1
fi
if [ "$CHANNEL_HOP" -eq 1 ] ; then
# channel hop in the background
channel_hop &
fi

match($21, "SA:aa:bb:cc:dd:ee:f1") {
print $21
system("mosquitto_pub -h 192.168.1.100 -p 1883 -t cmnd/athome -m yes")
system("") # flush the buffer
}
match($21, "SA:aa:bb:cc:dd:ee:f2") {

}其原理是wifi被动侦测,我们手机wifi功能在打开的时候,会后台不停地探测手机周边是否有可以连接的wifi路由器,这个探测的动作,就会被openwrt无线路由器里执行的tcpdump脚本记录到.就算你手机当时没有连上无线路由器,仅仅是靠近该路由器你都被记录了,然后按第二个脚本触发mqtt命令
回复#9 @hi_aardio :
是的靠近即刻被记录到。
遇到的是开放式不需要密码的 wifi, tcpdump一样是会记录任何靠近的默认开启WiFi功能的手机,
只要手机尝试搜索附近的WiFi就会发出Probe requests动作,发生此探测动作就会被tcpdump记录到。(附近的WiFi无线路由器收到手机探测动作,也会回应一个Probe Respond动作.....后面才会有可能发生WiFi连接握手之类的请求)
你不想被记录到,只有暂时关闭手机的WiFi功能,总之你开了WiFi功能,不管你连或者不连WiFi,仅仅靠近ap(WiFi无线路由)而已,都会被有心的tcpdump记忆到你手机的探测动作。

有意思,就是没硬件设备,(●—●),改天去淘宝弄个集成IO网络控制板,也玩玩物联网
