Smart lighting saves energy, increases comfort, and is more affordable than you might think. Find out if it's worth it for your home.

What is smart lighting?

It's any lighting system you can control remotely, by voice, or automatically. Wi-Fi bulbs, LED strips, smart switches – all connected to your smartphone and compatible with Alexa and Google Home.

Real advantages

• Energy saving – Smart LEDs consume up to 80% less than incandescent bulbs. With automatic routines (turning off when leaving, dimming at night), your bill will visibly decrease.
• Total comfort – Warm light for relaxing, cool light for working, adjustable intensity without leaving the sofa.
• Remote control – Forgot to turn it off? Do it from your phone from anywhere.
• Automations – Turns on at sunset, turns off at a set time, reacts to motion.
• Security – Simulates presence at home when you're away.

Is it worth the investment?

A smart Wi-Fi bulb costs between €10 and €20. The difference compared to a normal bulb pays for itself in a few months with energy savings – especially with active automations.

Where to start?

Start with one room. Replace a bulb, connect to the app, create a simple routine. In less than 10 minutes, your first automation will be working. Then expand at your own pace, room by room.

Examples of popular automations

Bedroom: Light that turns on gently in the morning to wake up without a sudden alarm.

Living room: Intensity automatically reduced at the end of the day.

Outdoor: Garden light turns on at sunset and off at sunrise.

Security: Lights turn on and off randomly when you're on vacation.

Does it work without internet?
Basic control works locally, but automations and remote control require an internet connection.

Is it compatible with Alexa and Google Home?
Yes. Modern devices support both assistants, as well as Tuya and Smart Life.
