First of all, know that if you want to equip yourself with a connected switch, your installation must be equipped with these wires:
1 / The Live phase (red or brown, with "L" for "Live"),
2 / The neutral (blue, with "N" for "Neutral")
A neutral wire is therefore essential for installing a switch
Which bulb to choose?
The Konyks Interi switch allows you to vary the light intensity of the LED bulbs to which it is linked.
So it is necessary to associate a dimmable bulb.
If a bulb is dimmable, it means that it is compatible with an LED dimmer also called an LED dimmer.
On the other hand, it is not necessary or even not recommended to associate a connected bulb.
