How to install Dimmer 211 on two way switch with 3 wires?

[svenvdc 0]

I have tried to install a Fibaro Dimmer 211 module in various ways based on diagrams found on internet, but without succes. 

 

As you can see in the attached diagram, I have two switches that switch 2 lamps (only one on the diagram).

Currently my switch has 3 connections: a double brown, a gray and a black wire. 

I have shown the other existing wires in the switch box in the diagram (an additional brown, 3 blue and 3 green)

 

Can anyone tell me how to correctly install the Dimmer 211? 

 

Many thanks in advance,

Sven

This is a very good start, they have diagrams for various setups you should be able to find what you want or adapt for a 3 wire setup.

Edit: And you do have pushbuttons I? It won't work otherwise.

Thanks Joacim,

 

i'll check out the diagrams also.

i do not have pushbuttons, but I read it should work with switches also?

I don't think you will be able to dim the light if the buttons aren't monostable or spring loaded. It may work turning it on and off to a pre set value.
