Fibaro dimmer 2 and Hotel setup (2 push devices)

[rgroothuis]

I've a Fibaro dimmer 2 installed, using a Push switch/device for enabling/disabling the light. Wires are connected on Sx and S1. This is working fine. Now I want to connect a second Push device (hotel schakeling), the second push device is connected parallel to the first one, so also on Sx and S1. The 2 black wires are inserted into the 1st Push device. Now the strange things happen. The 2nd Push device is not working at all and the 1st Push device is also not working anymore or has strange behaviour.

How is this possible? One Push device is OK, working fine, adding 2nd Push device in parallel and it is not working anymore. Really strange.

It is a Led light, so maybe the load is the problem. I've ordered a bypass, maybe that is the solution.

Any other suggestion what could be the issue? Thanks.

I resolved the problem my self. Not sure how I did it, but disconnecting the Fibaro dimmer, connecting all the wires again etc, resulted in the fact that it is now working incl the extra hotel switch. Maybe a recalibration after power on was the trick.
