I have a Fibaro Dimmer 2 connected through the 3-wire system.
Because I have a Hue bulb, which needs constant power, I have not connected this light to the dimmer directly. My intention is to use the Dimmer 2 only for scene activation through the pulse switch which is connected to the dimmer.
The black wire is therefore connected to brown (L) and the Dimmer’s output is empty.
The dimmer itself has brown (L) and blue (N) wires attached so it has power.
The Jung Pulse switch is connected to S1 and Sx.
I can include the Fibaro Dimmer 2 in homey and when I press the pulse button the red lights turns off for a moment. Nothing happens otherwise.
I have a flow with a trigger: IF: Dimmer 2 scene (pulsdruk)
Left (S1) pressed 1x THEN: Philips Hue turn light on
Scene activation (parameter 28) is on.
Switch type (parameter 20) is set to pulse switch.
According to the Fibaro Dimmer 2 manual, a red light means “Calibration procedure failed. Possible reasons: lack of connected load or connected light source exceeds maximum power, which may be controlled by the Dimmer 2.”
Which is to be expected, because there’s no load attached to your dimmer. So at least during calibration, a load (either a light or a Fibaro Dimmer Bypass device) needs to be attached. And quite possibly, it will require the load to be attached after calibration as well.
I’ve replaced the Hue bulb with a dumb bulb and the Dimmer is working properly, after calibration.
But I would really like to use a Hue bulb here because of the rgb-functionality and the easy to use app, which also contains all my other lights.
I didn’t count on using a dimmer bypass, because it seemed only to be required when facing flickering LEDs. Can this bypass also be used to completely bypass the dimmer and how will the wiring look? I’m going to look into this right now…
