Multiple dimmers 2, same lamp, only 1 load



Hi all,


I have 3 switches with fibaro dimmer 2 behind, 2 of them with a bypass but no lamp and one with the lamp. I would like all three dimmers to control the same lamp (on/off, dimming if possible)

I tried associations but it works very poorly (only 1 switch will control the lamp, the others will become obsolete).

How do I do that?

Here is a schematic-ish:

1. Dimmer 2 --> power + bypass (no lamp)
2. Dimmer 2 --> power + bypass (no lamp)
3. Dimmer 2 --> power + bypass + lamp

I do I control 3 using 1, 2 and 3 ?

Is it possible to connect the three switches together with cable? This is the easiest solution from a Fibaro point of view. For areas like stairwells and hallways, such cabling is common. That way you on need one Dimmer 2. But given your setup, I assume that this is not possible.


Another alternative is to run a scene when a switch is activated. There is a parameter for this that you will need to change on each device to allow scenes to run.  The same scene would be set to trigger from each device. The scene checks If the light is on, then it turns it off. If the the light is off, then turn it on.
