> adding smart features to previously dumb devices is nice at first, but what about in five years when the software will start to rot and stop working, and probably become a serious privacy and security liability? There is easy solution - instead of IP-based IoT devices, separate appliance network based on industrial or specialized bus (e.g. Zigbee) and then gateway connected to IP-based network. With this setup all your appliances, switches and lights are pretty well isolated and with trivial software, and you just need to handle software updates and security in gateway. There is another problem and that is interoperability and long-term availability of these products. I do not want to buy products from a closed system of one vendor, but prefer some industrial standard, so there is hope compatible products would be here even after 10 or 20 years.
