Articles demonstrate just how massively overhyped IoT is
The problem with the exampels for teh IoT as with almost everything I have seen is that the IoT makes products more expensive, functionally fragile, create security risks and does not add any benefits.
A smart iron is a great idea except that there is no need for the IoT but a machine readable ironing prescription on items of clothing. They already have human readable ironing prescription. IoT needs a machine readable unique item identifier or similar so has the same requirments on the clothing but adding the IoT has added no beenfit at all while complicating things and making the system more fragile. Using a smart phone's camera and bar code reading SW makes sense but then you just have a bluetooth connection to the iron and an App. Not really IoT at all.
The smart electric blanket, OK, but a better product has the body temperature cycle support built into the blanket, again why involve the IoT what is the benefit? I can only see downsides.
