Smart dimmers
A smart dimmer smoothly sets the light to suit the mood and time of day – gently brightening in the morning and dimming in the evening. Fit it behind the existing switch and control brightness by button, phone, voice or automatically.

How to choose a smart dimmer
Most importantly, the dimmer must match your light source. Dimmable 230 V LED bulbs and fittings use a standard in-wall dimmer, LED drivers with a 0–10 V input use a 0/1–10 V dimmer.
- In-wall – Shelly Dimmer Gen3/Gen4, FIBARO Dimmer 2, Nice Dimmer.
- Dual channel and DIN – Shelly Pro Dimmer 2PM for the board, two circuits.
- 0/1–10 V – for LED drivers and fittings with an analogue input.
- No neutral – FIBARO Dimmer 2 and other models, with a bypass for low loads.
If LEDs flicker or glow when switched off, a bypass helps. For colour light use LED strip controllers or smart bulbs.
Frequently asked questions
Can all LED bulbs be dimmed?
No, only those marked as dimmable. Non-dimmable LEDs may flicker or be damaged.
Why does the LED flicker with a dimmer?
Usually due to low load or no-neutral wiring. A bypass or changing the dimming mode (leading/trailing edge) helps.
Will my original switch still work?
Yes, we recommend replacing it with a push button – a short press switches on, holding changes the brightness.
