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`)  |
