I think the main thing that's lacking is good AI for these devices to work well together. The Nest does it pretty well, but the rest of these devices clearly don't. As an example, I'd love blinds that knew my phone's alarm time and started letting in more light shortly before then, so that I can wake up then, without being woken up well before then. I've already made windows that open and close based on the outdoor temp and forecast, to store up thermal energy (or lack of) in anticipation of the highs/lows later that day. These could work with blinds to let in/keep out sunlight, depending on the system's thermal needs. You could also tie in awnings. Between these, you could have self regulating temperature with much less energy use than depending on a traditional HVAC system.
