Most Apple Home accessories are controlled from the Home app, through Siri or automatically using Scenes and Automations. There is another useful option that many people may not be aware of.
An NFC tag is a small, inexpensive wireless tag that a compatible iPhone can recognize when it is held nearby. The tag does not need a battery and can be placed almost anywhere, making it possible to create simple physical touchpoints around the home.
Tap an iPhone near a tag beside the back door, for example, and it could trigger actions associated with outdoor lighting. A tag beside the bed could start a nighttime routine. Another in the garage could provide quick access to commonly used smart-home controls.
An NFC tag can turn a physical location around the home into a shortcut for an action on the iPhone.
What Is an NFC Tag?
NFC stands for Near Field Communication. It is the same general type of short-range wireless technology used for many tap-based interactions with smartphones.
NFC tags are small chips containing information that can be read when a compatible phone is brought very close to them. They are available as stickers, cards, key tags and other small formats.
For smart-home use, the important part is that the tag can be used as a trigger for a personal automation on an iPhone.
The tag itself does not connect to Wi-Fi, Apple Home or the smart-home accessory. The iPhone recognizes the tag and then performs the action that has been assigned to it.
How to Set One Up
The setup is handled through Apple's Shortcuts app rather than the Home app.
Open Shortcuts, select Automation and create a new personal automation. Choose NFC as the trigger and scan the NFC tag with the iPhone.
The tag can then be given a recognizable name such as Backyard Lights, Good Night or Garage.
Next, choose what should happen when that tag is scanned. Depending on the desired setup, a Shortcut can perform actions or control compatible Apple Home accessories and Scenes.
Once configured, bringing that iPhone near the tag can trigger the assigned personal automation.
The physical trigger
A small battery-free tag placed somewhere convenient around the home.
Performs the action
The iPhone reads the tag and runs the personal automation or Shortcut assigned to it.
A Physical Shortcut for Outdoor Lighting
Outdoor lighting provides a simple example.
An NFC tag could be placed inside near the door leading to the backyard. Scanning it with an iPhone could run a Shortcut that controls compatible outdoor lighting.
For a Channel Master Pro-Floodlight, this could provide another way to control the light through the Apple Home environment without opening the Home app and locating the accessory each time.
A homeowner with several compatible outdoor lights could instead have the NFC automation activate a Scene that sets multiple devices at once.
This could be useful near a patio door, garage entrance or another location where the same smart-home action is used regularly.
Use NFC Tags With Scenes
NFC tags become more interesting when paired with Apple Home Scenes.
Consider a Backyard Evening Scene that sets patio lights, landscape lighting and a Pro-Floodlight to the desired settings.
That Scene can already be selected from the Home app or activated using Siri. An NFC tag provides another way to start the same routine.
A tag placed near the patio door could become a physical shortcut to the Scene. The homeowner taps the iPhone near it before going outside and the configured actions run.
The Scene remains in Apple Home. The NFC tag simply provides another way for the iPhone to initiate it.
Other Practical Uses
The same idea can be applied throughout the home.
Bedside: Run a nighttime Shortcut or Scene without navigating through several controls.
Entryway: Trigger a commonly used arrival or departure routine.
Garage: Provide quick access to compatible garage, lighting or other smart-home actions.
Home office: Set lights and other compatible devices for the workday.
Patio: Activate an outdoor Scene before spending time outside.
An NFC tag can also be hidden behind or underneath some nonmetallic surfaces, allowing it to remain unobtrusive while still being accessible to the phone.
There Are Some Limitations
NFC tags should not be confused with regular Apple Home accessories.
The tag depends on an iPhone to read it, and NFC personal automations are associated with the device and user that configured them. A tag placed by the back door does not automatically become a shared Apple Home control for everyone in the household.
Placement matters as well. NFC operates over a very short distance, which is useful for intentional tap-style actions but means the phone needs to be brought close to the tag.
For controls that everyone in the household needs to use regularly, a conventional switch, Apple Home-compatible button or another shared control may be more appropriate.
A Simple Addition to Apple Home
NFC tags are not necessary for building an Apple Home, but they provide an inexpensive way to experiment with physical shortcuts.
The setup is straightforward: place a tag somewhere useful, configure the NFC trigger in Shortcuts and assign an action that makes sense for that location.
For someone already using Apple Home Scenes and compatible accessories, NFC tags provide another option alongside the Home app, Siri and automatic triggers.
Sometimes the useful part is simply having the control exactly where you tend to need it.
