Calling the zwave_js.multicast_set_value service with a light group containing a Z-Wave LR Dimmer switch fails

foxxcomm commented 1 month ago

The problem

Calling zwave_js.multicast_set_value to turn on or off a light group fails when the group contains a Z-Wave 800 LR dimmer switch. In the example provided, the light group contains 1x Inovelli VZW31-SN included as a Z-Wave 800 Long Range node and 1x Inovelli VZW31-SN included as a normal Z-Wave mesh node. Both dimmer switches are included in the same Z-Wave network. If the light group is modified to contain 2x Inovelli VZW31-SN dimmers included as normal Z-Wave mesh nodes, the service call works fine.

As of today, node-zwave-js does not support creating mixed LR and non-LR (mesh) multicast groups. If it would, the call would internally be translated into two singlecasts anyways, since LR and mesh are two different protocols.

@AlCalzone - Thank You for your continuing great work on Z-Wave JS! Agree with you when there is only 2x in the group. For larger groups of switches however, it would make sense to support someday if possible. Suggest adding a section in the documentation on current LR restrictions/quirks (No beaming, Mixed Multicast) and any others not well known.
