Problem with momentary switch after replacing FGS212 with FGS213

[ronaldQ 0]

Hi all! Couple of years ago I equipped a momentary switch with the Fibaro Single Switch (FGS212) and everything works like a charme. Recently I wanted to replace the FGS212 with the Single Switch 2 (FGS213) due to the advantage that the FGS213 supports SceneActivations. But unfortunately I can't get this to work properly: if I connect an FGS213 and configure it as a momentary switch (all other parameters are on default), I have the following behavior: I can turn the light on using the hardware switch (switch on the wall) but can no longer turn it off. I can then turn the light off via the HC2, but when I turn it on via HC2, it immediately switches off again. If I remove the cable from S1, at least switching via the HC2 works as it should (of course not via the hardware switch at all). As soon as I install the old FGS212 again, everything runs smoothly. What am I doing wrong here? (by the way, the FGS213 works without any problems on a toggle switch)?

 

Attached two pictures from the wiring.

 

Thanks!

L should be connected too.

Tried that (by bridging to the general L - similiar to the FGS212 connection) but getting the very same behaviour (see photo). What am I doing wrong?

 

FYI: I got the following feedback from the Fibaro support (which I find quite strange):

The Single Switch 2 unit is not meant to be used with light sources. It often causes the transmitters inside the switch to stick together. This behaviour is also observed with the older Relay Switch unit, the one you are currently using. However, these units use different connection terminals which might explain why your device is still operational. For light sources please use a Dimmer 2 unit - FGD-212.

 

Regards,

Ronald
