Hi all,

I’m struggling with my fibaro dimmer II.  
I have 2 dimmers that have the same behaviour.

When connecting the dimmers in 2 wire setup the green light is burning. A long press of the B button (hardware pair button) doesn’t result in an menu sequence (yellow).

```
Press and hold the B-button to enter the menu mode
Wait for the visual LED indicator to turn yellow
Quickly release and click the B-button again

```

The switch itself won’t turn the bulb off either but stays on.

Anyone has ideas how to get this out of this state?

I have paired them with homey before, did not remember if I successfully unpair them.
