I have the same problem with Fibaro dimmer 2. They do not dim low enough. That problem is solved by changing minimum brightness to 2. BUT that also causes the dimmer to take a long time to turn the lights on. Up to 5 seconds from pushing the switch to the lights turn on.

When I recalibrate they turn on instantly, but the minimum brightness problem is back.

Does anyone have a simmilar experience.

It’s really confusing. With the MIN BRIGHTNESS LEVEL set at 1, the light only dims to about 50% of actual brightness (even if the app can be dragged down to 1%). As I learned from this thread, setting the MIN BRIGHTNESS LEVEL to anything other than 1 works to get the bulbs down as low as they should go (I actually set it to 1.1 and miraculously my lights now dim low). Switching off then switches the light off properly. So far so good.

However, switching on again tells the module that the light is “on” (ie the app shows it having switched on) but **there is no light** from the bulb. If (using the app), I slowly bring the brightness up, the light does not react until I get to a level which is equivalent to previous brighness level it achieved before changing the MIN BRIGHTNESS LEVEL setting.

I have examined (but not played with) all the parameters and can’t seem to find anything that this can relate to.

Any thoughts greatly appreciated, I’m tearing my hair out here.

Posting my solution here just in case anyone is interested. It’s clunky but it works.

When the paramter is set low and then turned off, turning them back on again leaves the brightness below a visible level (but the lights _are_ on), so they need to be turned up again. So I use a flow to simply increase the brightness

- After calibrating, set calibration parameter to “Readout” on the Fibaro Dimmer 2 Advanved Settings so it doesn’t try and over-ride anything
- Set minimum brightness level to 1.1 on the Fibaro Dimmer 2 Advanved Settings

Now create a flow for the circuit as follows:

- **When** Lights turned on
- **And** dim level \< 0.2 (play around with this parameter)
- **Then** Dim lights to 0.011 (again play aropund with this parameter)  
(NB dim level is represnted as a decimal here, not a percentage)

As I said, clunky, but my lights now operate as they should.
