I've said this before and I'll say it again: A truly "smart" home is one which has proper thought that went into the design, not how many gadgets and IoT devices you can cram into it. Proper placement of power points and light switches along with "banks" of lights in large rooms and the addition of dimmer switches is something easily done.
Sometimes simple is better. For example, I don't use an electric kettle. I use a gas cook top with a stainless steel kettle to boil my water (and yes, it even whistles to notify when it's finished). No electric elements to die, it looks nice and does the one job it's required to do perfectly.
