If you want to let all of your Facebook friends and family know you are at home, you can "check in" your location. Checking in gives friends the exact location where you are in a status update that is viewable in their News Feed. When you check in, you can opt to select a nearby location or add your home as a location. You can even tag other friends who are with you at home in your status update.
Open the Facebook app on your mobile phone. If the app is not installed on your phone, open the Web browser and access Facebook.com. Log into your account.
Scroll down to the "What's On Your Mind" status update section. Tap "Check In" under the update section.
Enter "Home" in the search field, then scroll down to the bottom of the results.
Tap "Add 'Home'," and add a description of what you are doing or the location if you want.
Tap "Tag Friends with You," and select any friends you want to check in with you.
Tap "Check In" and your status will update in your friends' News Feeds.
