The Fibaro Dimmer is no longer available and has been replaced by the Fibaro Dimmer 2.

Fibaro Z-Wave Dimmer insert module retrofits into an existing light switch enabling you to wirelessly control lights. The Fibaro modules are the smallest available, measuring just 17mm high, and can be used in 2-wire (no neutral) lighting installations.

Universal Dimmer 500W (FGD211)

Wireless Dimmer designed to work with any light source.

  • Works with incandescent bulbs, 230V halogen, 12V halogen and dimmable LEDs
  • Supports 2-wire (no neutral) and 3-wire installations - further information is in our 2-wire/3-wire guide
  • Second switch input for controlling additional associated devices or 2-way installations (see note)
  • Various switch types - momentary (default), toggle, 1-way and 2-way
  • Requires Fibaro Dimmer Bypass for loads less than 25W - further information is available in our Fibaro Dimmer and LED Guide
Note: Using Second Switch Input

The Universal Dimmer allows a second switch to be connected to the module which can be used to control an additional Z-Wave device associated with the Fibaro module or in a 2-way lighting installation. More information is available: Application Note 18 - Using a Secondary Switch with a Fibaro Module.

Fantastic devices and now can launch scenes!
Have bought a number these devices over the last few years and the latest releases really are great. The secondary input is really useful as cannot only associate with other devices but also launch scenes via your controller. So in the UK in older houses they can be a pain as ideally you have 45mm backbox, they can be installed in 35mm but need a little bit more poking around. 25mm forget it, get out the SDS drill and make a bigger hole. They are fantastically reliable over the 3 years ive owned and never had an issue.

Good product
Nice and easy to install. Using a standard(UK) wired house, followed the instructions on the Vesternet article. I'm using LEDs (6x7W), they seem to work fine. One annoyance is the unit seems to buzz when the lights are dimmed...

Fibaro Dimmer
Great product. Installed as part of a home renovation, works well and fast to respond. Nice "soft start" feature - lights dim on and off, makes you feel like you're in a posh hotel! Note - if dimming LED remember to check your minimum loads! (read tech guide on here) and install the Fibaro bypass if needed. Dimming Robus LED GU10 bulbs x 4 without bypass and a Philips LED bulb with bypass.

Very fast reaction, not so simple to install
this product is very responsive and good quality build but if you are unfamiliar with how 2-way lighting works it can be a bit daunting to wire up in stairway lighting. Another issue is that the space in a standard uk socket is quite small and this unit takes up slightly more than a quarter as well as about 2/3rds the depth. If your switch uses a lot of depth already you might have a tight fit. You will also need some electrical wire to fit this which it does not come with.

These are really flexible, they can be used for many different variations of lighting, very impressed.

more than just a dimmer - Fibaro Dimmer module
adds capability to existing systems, allows for a modular upgrade / install of complete home automation system without breaking the bank. Bit by bit the system is taking shape but at every stage you get extra benefits.

Excellent dimmers, working well with Homeseer HS3. You will need the dimmer bypass if your lighting load is low.
