I have a few 'smart' things in my house. One is my living room mood lights, but that's a combination of a simple RF plug relay switch on the one hand, and an ikea (also RF?) spot system, no internet required.
The other thing is my thermostat, where it's mainly convenience to control it remotely via my phone. I'm not comfortable with it, it has a dongle directly in my router giving the company behind it access to it and its data. I mean the charts are convenient, but I think the whole thing could be made offline as well. Anyway, that one has a simple screen (LED light matrix?) and touch buttons so anyone can adjust the temperature until the next time block, making just the unit without the app as useful as the old dial thermostat it replaced.
Final 'smart' thing I have is my wifi router, which I can manage via my phone; a big improvement over the old router/modem which had a very 2000's looking web interface.
