I've been doing home automation stuff on and off for about 10 years now. It seems like every new device in the past few years has to have a connection to the internet and be controlled through a web-connected app. In some ways I kind of understand this: so many people have a smartphone, and they already know how to get it online, so if you connect your "IoT" device to the internet then you kind of get your remote control for free.
However, the whole idea of broadcasting data from the inside of my house to some 3rd party server on the internet is such a crazy idea. I recently installed a whole home energy monitor (it monitors the incoming feed and a bunch of the main branch circuits). It does come with software that I was running on a local PC, but the main way that they recommend to use it is to sign up for an online service (around $2/month) and have it upload your data there. Since their software wasn't great, I was tempted to do that... for about 10 seconds. Do you realize how much personal information that would mean transmitting to a 3rd party?When your stove, microwave, dishwasher, and washer/dryer runs? No way! Looking at the data it's pretty easy to pinpoint when we're there and when we aren't. In the end, I opted to write my own logging and reporting software, and that gave me the ability to add some useful features, like emailing me if the backup sump pump turns on (meaning my main sump pump has stopped working for some reason). Still, most people just have to take what's offered, and I think that's pretty scary.
Also consider the nest thermostat, which has an occupancy sensor, or the Xbox 360 which has a camera that's reportedly "on" all the time looking at your living room. This isn't a good idea.
