Re: What is 'Smart'?
Unless the the item is approaching laptop prices I doubt there is much in the way of either hardware or programming that could be honestly described as smart or intelligent
You mean like a Raspberry Pi? Or a £50 smart-phone? The whole driving force behind IoT is that fairly powerful computers are now dirt cheap to the extent you can put them in stuff at little extra cost.
These things could work great - your smoke alarm raises your house lights (maybe leaving the kids' rooms out for you to alert them).
