A smart home does not mean 20 devices and three applications. The goal is for the home to work for you — quieter, faster and simpler. These are the things that have the greatest effect without complications.

1. Smart lighting — but minimal

You don't need dozens of smart bulbs. Two scenarios are sufficient:

• evening light (warm, calm)
• morning focus light

One switch, two scenes — and that's it.

2. One central application

If you have to open three apps to turn off the lights, the system doesn't work. HomeKit, Google Home or SmartThings — choose one.

Minimum set-up that works:

• smart plugs
• one or two smart bulbs
• phone shortcuts

3. Automations that really help you

Micro-automations that make the biggest difference:

• turn off all devices with one click
• morning routine: light + music
• evening routine: dimming the lights

The simpler the system, the longer you'll use it. Complications kill motivation.
