Automation that works
Your home, in tune with the way you live
Lighting, air conditioning, ambient sound, curtains, audio and video in one easy-to-use system, customized for you.
Everyday scenes
By day, when you walk into the kitchen, the main light turns on by itself.
At night, only the LED strips set the mood. All without touching a switch.
Left home and the living room is still on?
No problem. The system detects that no one is home and turns everything off for you.
Got home and want to hear some music?
Just give the command. Your sound system is ready to set the soundtrack for the moment.
Movie time?
When you turn on the TV or the projector, the lights dim, the curtains close, and the air conditioning adjusts itself. All you have to do is choose what to watch.
Away from home and left something on?
Q-IA lets you know on WhatsApp and asks if you want to turn it off.
Bedtime?
With a single command, lights and devices switch off, leaving the house ready for a peaceful night.
