![]() ![]() It can contain any standard alpha-numeric characters and must exactly match (case sensitive) the Secret parameter field on the Crestron processor. Secret Key – This field is added for security purposes to help assure that someone sending random http messages cannot trigger actions on the Crestron system. When an http message is sent by the smart phone to the Crestron processor, the Tag_Scanned digital output associated with the matching Tag_ID field will be pulsed and can be used to trigger smart home actions on the Crestron system. This field must exactly match (case sensitive) one of the Tag_ID parameter fields in the Crestron module. Name for Tag Action – As written, the Crestron module supports up to ten NFC tags (it is easily expandable to support more by editing the Simpl+ portion of the module). This must match the entry you make as a parameter in the Crestron module Processor Port – The port you are using for communications. Processor IP – The IP address of your Crestron processor on your home’s network Scroll down and from the list of items under the category “Web Requests” choose “Get Contents of URL”.From the categories of actions choose “Web”.Press the “Add Action” button in the Shortcut app.To create the linkage to the Crestron driver I wrote: I’ve written a module for a 3-Series or 4-Series Crestron processor that allows http messages sent from a smart phone when an NFC tag is scanned to trigger logic running on the Crestron processor. I’m going to provide information on integrating NFC tags with a Crestron smart home processor, IFTTT, and a Hubitat Elevation hub. ![]() Press the “Next” button in the upper righthand corner of the screenĪt this point you are ready to create the linkage between the act of scanning your NFC tag and your smart home.Scan your NFC tag by holding the phone next to it.Press the button labeled “Create Personal Automation”.Press the “+” button in the upper righthand corner of the screen.Select “Automation” from the menu bar on the bottom of the screen.There is an article on the Android Authority web site that describes the process. It is my understanding, however, that the Android Tasker app can be also used to accomplish the same thing. I am an iPhone user and don’t have an Android phone to test with, so this article will focus on how to use the Shortcuts app on the iPhone to integrate NFC tags into a smart home. The same is true for newer Android phones. Most newer iPhones (iPhone 7 and newer running at least iOS 11) are NFC enabled and can be used to read NFC tags. For this article I purchased a package of 30 NFC tags for $11.99 + tax with Prime shipping on Amazon. NFC tags are inexpensive and are readily available on Amazon, eBay, and other shopping sites. A reader, such as a smart phone, can then take actions based on the identifier it receives. The reader and the NFC tag can then communicate with each other.Įach NFC tag contains a unique identifier that will be transmitted to the reader. That current provides enough electricity to power the device. ![]() When an NFC reader is placed next to the NFC tag, an alternating magnetic field generated by the reader induces a current in the NFC tag’s antenna. Only about 1/32-inch thick it has adhesive on one side so it can be attached to almost any surface.Īn NFC tag doesn’t require batteries or a connection to a power supply. A typical NFC tag, which could be used in a smart home, is just a thin, plastic disk, about the diameter of a quarter. NFC tags are small devices that consist of a microchip and an antenna enclosed in a substrate.
