Find My tracker in a loft, garage or attic: what to expect

How does the Find My network work for a stored tag?

The network is not a set of masts. It is the iPhones, iPads and Macs that pass your home, and any of them can detect a tag's Bluetooth signal, encrypt the sighting and send it up to Apple without the owner knowing. According to Apple's published description of the network, the location is end-to-end encrypted, so only the tag's owner can read it.

That design suits a tag on a train or in an airport, where thousands of devices pass every hour. A box in a loft is the opposite case: the signal has to reach someone walking or driving past the house.

Will a tag in a loft report its location?

Often it will not need to. If you are at home, your own iPhone is the device nearest the box, and Bluetooth will usually connect when you stand underneath the hatch. The network matters only when you are away and want to know where the tag last was.

In a quiet street, few Apple devices pass. In a terraced road with a school nearby, many do. The honest answer is that it depends on your address, and the test is to look at the Find My map after a few hours and see how current the timestamp reads.

Does a garage change anything?

A garage matters mostly because of the door. A metal up-and-over door absorbs a good share of a 2.4 GHz signal, while a wooden one hardly does. An attached garage with a brick wall to the house is easier for your phone than a detached one at the bottom of a long drive.

Placement inside the garage also counts. A tag in a plastic box on a shelf near the door will be seen far more readily than one inside a steel toolbox at the back.

Where should I put the tag in a stored box?

Put it near the top, inside the lid if you can, and away from metal tins and foil-wrapped items. A cardboard or plastic box passes the signal reasonably well, and a layer of bubble wrap does little harm. A metal cash tin, a biscuit tin or a cooler bag with a foil lining does a great deal.

Test the position before you stack more boxes on top. Ring the tag from the doorway, then from the foot of the stairs.

How Locata Tag helps

A Locata Tag is a Find My compatible tracker that shares the same network a travel bag would use, and the same Play Sound button. Rings reach up to 60 metres in open air, so inside a house the question is the walls and the hatch, not the range. Past Bluetooth range, nearby Apple devices can relay a sighting to your Find My map. It needs an iPhone, it is IP67 rated, and the replaceable CR2032 lasts up to two years, so a tag left in a garage box over a winter will usually outlast it.

It cannot point an arrow at the box, so a ring and a map pin are what you have. See the product page for the two-pack.

Frequently asked

Does Find My work in a loft with no signal?

The tag itself needs no mobile signal because it talks to passing Apple devices over Bluetooth. Your own search from inside the house works the same way, with your iPhone connecting to the tag directly when you are close.

Can a metal garage door block a Bluetooth tracker?

Yes, a steel door absorbs and reflects much of the signal, so a tag behind one may be seen only when your phone is near the door. A tag nearer the house wall or a window fares better.

How often does the tag update its location?

It updates when a device passes and detects it, so a busy road gives frequent updates and a quiet one gives few. Read the timestamp on the map rather than assuming the pin is current.

Is a tag safe in a cold garage?

A CR2032 coin cell loses some capacity in the cold, so a tag in an unheated garage may run shorter than the two-year figure. Check the battery in spring and keep spare cells out of reach of children.
