Domoticz是一款家庭自动化系统，而lua motion sensor是一种用于监测运动的传感器。

当 Motion Sensor 探测到 X 分钟没有活动时，此脚本将关闭第二客厅的灯光。

脚本确实在运行并且有时能正常工作，大约每天一到两次。但它必须始终工作，我无法弄清楚为什么它不起作用。

t1 = os.time()
s = otherdevices_lastupdate['Motion']

year = string.sub(s, 1, 4)
month = string.sub(s, 6, 7)
day = string.sub(s, 9, 10)
hour = string.sub(s, 12, 13)
minutes = string.sub(s, 15, 16)
seconds = string.sub(s, 18, 19)

commandArray = {}

t2 = os.time{year=year, month=month, day=day, hour=hour, min=minutes, sec=seconds}
difference = (os.difftime (t1, t2))
print(difference)

if (otherdevices['Motion'] == 'On' and difference > 60 and difference < 200) then
    commandArray['Light']= 'Off'
    print('2 minutes no movement, turn off Light 2th Living Room')
end

return commandArray
