Fibaro Dimmer Bypass 2

The Dimmer Bypass enables the Fibaro Dimmer 2 module to control lamps which have a power of less than 50W. It is ideal for use with low-power LED lamps.

The Fibaro Dimmer 2 and Dimmer Bypass can only be used with lamps that are 'dimmable'. Before buying this product, please confirm that your lamp can be dimmed.

Very solid once paired
These devices are small and appear to do what they say on the tin. The only problem I have had is with pairing which you only need to do once hopefully. Using a Vera Plus as gateway and have nearly given up on the device as the pairing has repeatedly failed. Just about to give up when pairing succeeded (after an hour or so!). It went through calibration and sorted itself out with no problems whatsoever. Have non dimmable leds so cannot comment on dimming but they have worked without problem for over two weeks.

Works as it should
I had fitted to LED dimmable spot lights in bedroom then calibrated. I found that one was still very faintly on. I then realized the fittings were about 5.5 watts each under the 20 watts needed for the Dimmer 2, i then fitted the Bypass 2 and re-calibrated and the LED is now working as it should.

Worked after parameter change - but shame this is required at all
Previously my LED bulbs connected to Fibaro Dimmer 2 were still glowing even when the dimmer was 'off'. After installing this bypass it went crazy and would not calibrate properly, flashing on and off. I edited the device driver in Smartthings API to set parameter 13 to value 2 and forced recalibration. This fixed the issue and it now works properly.

Doesn't seem to make much difference
I purchased these to fix a number of issues I am experiencing with Fibaro Dimmer 2s. Unfortunately, this doesn't fix all of them. I have a pair of LED downlighters which still flicker when dimmed, even with the bypass installed. They seem to work well with compact fluorescent bulbs, however.

Replacing 2 1st generation dimmers, so need to replace the loads I've attached - found that 2 work well with a very low wattage bulb, so got extras in case they're needed with the new dimmers.

To enable Fibaro Dimmer 2 to work with LED lights
Simon C. 10 Jan 2016
I think I need this, since my LED lamp still glows a bit when it should be off, but am not clear on how it is meant to be fitted. The wiring diagram in the manual is hopeless - so do you have to put this inside the light fitting somehow ? I don't see where it would physically go, to bridge across the bulb. There are two lights driven by the same switch, so do I need to bypass them both ?
David P. 17 Jul 2017
Will this work with the latest Aeotec Nano Dimmer for which does not have a bypass available yet? I cannot beleive that the internals will be much difference between provisors - basically some additional resistance and capacitance added. Has anyone tied this and can report compatability?
Chris S. 19 May 2017
I'm unsure if they bypass is working/broken. Does it add extra wattage to the circuit?
