Endpoint is not dynamic, and is a Binary Power Switch

Configuration Z-Wave
1

Hello,

I’ve excluded all nodes from zwave network and make a factory reset on my zstick.
I’ve added first a 1 button dimmer which is working fine.
My 2nd device is a 3 button switch (manufacturer Vitrum)

I’ve added Group2 and Group3 to notify the zstick.

The first button is working fine as I get instant update: http://pasted.co/b6d7fe51
But for 2nd and 3rd button I get this: http://pasted.co/153a9e32

Any suggestions?

Thanks.
