Using NFC Tags to Simplify Smart Homes at Low Cost

There are many ways to control the smart home without having to look at the application of the phone or tablet slowly.

You can control the lighting through Amazon Echo, or voice-activated remote temperature controllers, or through Fitbit, when you get up, the coffee machine automatically cooks you a hot cup of coffee. Use the Flic and Pebblebee Stone smart buttons to control multiple devices with short or long presses via IFTTT.

The above mentioned various ways to make the smart home multi-connected devices easier to operate, but these methods are relatively expensive.

If you are an Android user, you can choose a more convenient and relatively inexpensive way to achieve your goals effectively. Here are the steps.

Condition requirements

If you already have an NFC-enabled Android smartphone or tablet, you only need to spend about $10 each, and each tag takes a few minutes to set up and use this feature.

First, you need to prepare some NFC (Near Field Communication) tags. Each automated operation comes with a label. It is sold on Amazon and is generally cheap. Then you need to install an application that supports writing NFC tags. I am using NFCTools, which is free to install.

In addition, you need to have an IFTTT account with the Maker channel activated. Users who already have an IFTTT account need only visit the website ifttt.com, click on “channel” at the top right, and search Maker to activate the Maker channel. Click the channel icon and then tap "Connect."

Maker channel using <br> <br> set up an NFC tag with IFTTT use, you first need to create a IFTTT menu by creating a channel. Even if you are familiar with IFTTT, you may find it difficult to use the Maker channel, but it is actually very easy to use.

Visit ifttt.com through the IF application on your browser or smartphone, create a new menu, enter the username in the browser, and click "Create" in the drop-down menu.

Click on the menu button in the top right corner of the IF application, then click on the Add logo in the top right corner, and click on "Create New Menu" under the application. Then create the Maker menu:

> Click This and search for Maker. Click the Maker icon.

> Trigger: Select Receive Network Request.

>Event Name: Use a name that clearly defines the operation, such as "switch light". Click on "Create Trigger"

> Next, click That to search for smart device channels. For example, when I use Lifx, I click on the Lifx icon.

> Select a Maker event operation. For example, when I name the event "switch light", I choose the "on/off light" operation.

> Select the lamp controlled by Maker event and click "Create Action".

>Click "Create menu" to complete the operation.

Set up an NFC tag

Now you only have to write a record for NFC. When connected to a tag, the NFC-enabled phone will access a URL so that the menu can be used.

> Open the IF application on your phone, click on the "Menu" button in the upper right corner and click on the set gear tag. Click on "Channels" and search for Maker channel.

> After opening the Maker channel page, click "How to create an event." Select and copy the URL under "Makea POST or GET web request".

> Next, open the phone's NFC Tools application and switch to "write tag" mode.

> Click "Add Record" to select the URL/URI.

> Paste the text into the URL bar, delete "https://" and replace "{event}" with the Event Name. For example, my Event Name is the "switch light" of the IFTTT menu.

> Select "https://" in the left drop-down menu and click OK.

> Click the "Write" button, the NFC tag is close to the NFC chip of the phone, and the record is written into the NFC tag.

Tear off the protective layer on the back of the NFC tag and attach it to the wall near the front door or near the door. Click on the phone's NFC tag, and after a few seconds, the lights in the room will be on.

You can use similar menus to trigger multiple events. For example, you can create a "home" menu, when you step into your home, tap the phone's tab to turn on the light, the thermostat activates the hot or air mode, and the door closes.

These tags are cheap and can be attached to all parts of the house. Put one on the coffee table and turn on the TV in the evening to dim the lights. One is affixed to the bedside and the coffee machine can be turned on when it gets up and turn on the light; the light is turned off when sleeping at night.
