I like the concept and it would solve the stated problems, however it’s not those problems that are holding me back from IoT. I do not want any IoT/home control device in my house communicating with anything in the cloud, period. Device makers have proven over and over again they cannot make secure devices, and I don’t want anyone collecting data on my usage. What is needed is something that can talk to a local server and doesn’t need the Internet.
