I renovated my house a few months ago and also had to decide whether or not to go &quot;smart&quot; on the lighting, switches thermostat, etc. Did a lot of research and came to the same conclusion that there was little benefit and large chance that I would have obsolete technology next year.<p>However, I did go for an electronic doorlock (with finger print reader) and after just a few months I can not imagine ever going back to having regular keys again. If you have a family with small kids and cleaning ladies that need to come and go this saves so much logistic hassle. No need to wait for a delivery man, just give him a temp code to put it in the hall, etc.<p>There are definitely a few great IoT things, but just like we once imagined a PC would be used to store recipes, we just have to find out what the truly useful IoT things are.
