A lot has to do with the fact that most of these devices are novelties. Save for smart thermostats (can save money on heating bill), or simple efficiency-boosting products, life is generally easier without the added complexity of an interconnected-everything. A fridge is a fridge and its proven to work well for over 100 years. A toaster makes toast. The dishwasher washes dishes. Once something more useful comes around companies will invest more resources but I mean who wants a smart toaster? You pop some toast in there and let it do it's thing. Simple. We need some major breakthroughs in, for example, 3d printed gourmet meals or something.
