I like to think of myself as a reasonably tech-savvy person. I’m pretty much on the computer all day at work, and I use a smart phone in my leisure time. And while I’m no digital guru I also like to think I know how things like the Internet work. But when it comes to the Internet of Things (IoT), up until recently I was a total novice. Which is a shame, really, because the IoT is all around us, and has been for some time.
