consider_home | 180 | Seconds to wait till marking someone as not home after not being seen. This parameter is most useful for households with Apple iOS devices that go into sleep mode while still at home to conserve battery life. iPhones will occasionally drop off the network and then re-appear. consider_home helps prevent false alarms in presence detection when using IP scanners such as Nmap. consider_home accepts various time representations, (e.g., the following all represents 3 minutes: 180, 0:03, 0:03:00) | 注意这个参数,默认是180秒,也就是当snmp检查到设备不在线180之后,才会判断为该设备已经离家,这样就可以避免短时间的wifi信号不好,造成的离家的假象,并非是snmp数据的更新不及时
