Fibaro FGR-223 association groups for cover position and slats position?

Configuration
1

Hi,

Using four FGR-223 connected to venetian blinds, this works correctly for setting the cover position (endpoint1) and slats position (endpoint2). I use 2 momentary buttons S1 and S2 on each switch.

I also have another FGR-223 (not connected to any blinds) which I would like to use as a group switch for the whole room. So far, only a partial success:

  1. I can control the cover open / close command for all associated devices (pressing S1 causes all sub-ordinated blinds start closing).
  2. I cannot control the cover position (i.e. a short press of S1 during “closing” phase normally stops the shutter at the current position. It does not do anything if I press S1 of the group switch.)
  3. I cannot control the slats position at all (i.e. a long press of S1 or S2 does not do anything with associated blinds).

As per user manual of FGR-223:

  • Association Group 2 “Roller Shutter”.
  • Association Group 3 “Slats”

For venetian blinds with momentary switches, the following actions are available for switch S1 or S2 for association groups:

  • on Click - 2nd group: Start/Stop Level Change
  • on Hold: n/a
  • on Release - 3rd group: Set Level.

I am confused about the meaning of the mappings last line as per user manual and as per Z-WaveJS UI:

User manual:

| ------------------- | ---------- | ----------------------------- |
| Root                | Endpoint   | Association Group in Endpoint |
| ------------------- | ---------- | ----------------------------- |
| Association Group 2 | Endpoint 1 | Association Group 2           |
| Association Group 3 | Endpoint 2 | Association Group 2           |
| ------------------- | ---------- | ----------------------------- |

In Z-Wave JS UI, the configuration uses different wording:

| ---------- | -------------- | ------------------- | --------------- |
| Endpoint   | Group          | Node                | Target Endpoint |
| ---------- | -------------- | ------------------- | --------------- |
| Endpoint 1 | Roller Shutter | Dining table window | Endpoint 1      |
| Endpoint 1 | Roller Shutter | Terrace window      | Endpoint 1      |
| Endpoint 2 | Roller Shutter | Dining table window | Endpoint 2      |
| Endpoint 2 | Roller Shutter | Terrace window      | Endpoint 2      |
... etc ...
| ---------- | -------------- | ------------------- | --------------- |

P.S. I created the association groups only for the group switch node. Do I have to do anything for the sub-ordinated switches (nodes) of each blinds?

How to achieve the functionality in point 2. (set cover position) and 3. (set slats position)?
