A little while ago over on the Web of Things blog we showed you how you could use NFC and the Trigger app to create a ‘cheap smart home’. The app basically lets you create actions that are triggered whenever an NFC tag is seen close to your phone (as in ‘touching your phone’ kind of close).
Don’t get me wrong, the app is awesome and I use it on a regular basis (my home is all NFC-enabled!) but it has two drawbacks:
a) it requires NFC and not everyone out there has an NFC phone (ahem… e.g. all iPhone users…); and
b) it requires an app, which means that people wanting to interact with your shiny NFC enabled doorbell will have to download an app first, not exactly the kind of thing you would want.
However, there is hope and it’s called a URL. In the Web of Things, all devices are accessible via URLs. So all you need to do in order to get data from a device is to use its URL.
If you want to learn in detail how to implement a cheap home automation system without the need to craft any line of code then head over to the Web of Things recipe blog post, plus you’ll find everything you need to get started in our eBay NFC-Automated Home Collection.
