I really don't need the current generation of smart devices. They are trying to solve a problem by applying quick fixes which don't work very well or need maintenance (changing batteries). I need a smart home where the built-in devices communicate and change behaviour based on sensor input and a controller where I'm in control of the software and open standards are being used. This also means that everything should work without internet access. Needing internet to turn a light on is pretty stupid. I'm thinking of you IKEA. I'm not going to waste my money on any smart devices before this happens.
