Problem is not with smart home software, but hardware. Ok, we now have "smart" lightbulbs. And even thermostats. Great stuff! I think, it is possible to have "smart" curtains. But I have simple example: now I'm living in country, when price for electricity changes every hour. I can extract this price programmatically without problems. Suppose, I want to wash my clothes when electricity is the cheapest, but no longer than 24 hours. No problem, algorithm is simple: calculate average price over, say, week (possible), look at state of washing machine, and if machine is prepared and ready (power-on, standby, program selected, door closed) and price is small enough (or there is a 23 hours passed from washing machine readiness), give machine command to start. I can imagine (and implement) Very smart algorithm when to start washing. But it needs washing machine, which can be polled for status and started remotely (but prepared locally, as software doesn't know did you want to wash color, white or black clothes, for example). Is here any such machine on the market? Nope... Same with microwaves, dishwashers, stoves, anything.
