Associate an endpoint with a a group

[lumbermatt]

Good evening to all,

I have a small question about Z-Wave I want to use to interface my old Merten switches (Schneider Electric Group) before the Z-Wave was abandoned by Merten. I have installed a RAZBerry2 module (ZWave.me) on my RaspberryPi4 and I have installed it correctly under Domoticz 2020.2.

I have two devices :

- Node 0x03 : a two-channel switch with 4 buttons (Merten Transmitter 2-Gang Switch - Ref. 506219) which has 4 groups (one per button) as detailed in the documentation.

- Node 0x04 : a two-relay module (Merten Receiver Flush-Mounted 2-Gang Switch - Ref. 507502) with two endpoints.

I was able to associate the two devices :

I can well control the relay module from Domoticz which appears as three switches :

Instance 1 and 2 : Controls the channel A
Instance 3 : Controls the channel B

I would like to associate the groups of the switch with the endpoints of the relay module. In the OpenZWave panel the endpoints are named 4.1, 4.2 and 4.3. In the "Group" Tab I tried to add on of those in the groupes of Node 3, they appear once added but the switch only control the Channel A with both buttons.

Does anyone know how to specifically associate an endpoint?

Thanks !
