One should be avoiding devices that contact some server in China before doing anything. Impossible find a lock for example that does not do that. So reprogramming is the only solution. But after that the one and only problem is that there is not enuff intelligence in devices. If my cellphone is not detected in wifi, there is no point on keeping various devices on. So lights and displays and gas stove can be turned off via wifi. But I cannot control water faucets without extensive renovation. Also window status on unclear at the moment. There is no point of cooling/heating if windows are open. The issue of front door opening automatically is under intense research at this moment. It is not enough that when the cellphone appears on wifi you should open the door. I think concurrent appearance on wifi and on movement sensor in front of the door could suffice securitywise.
