Per edge driver documentation, st.zwave.CommandClass.SceneActivation SET has no parameters. See Scene Activation Format
This is in direct contraction to the event received from the device:
<ZwaveDevice: e0d01d4f-0bf5-4ca2-8ac9-3fc660660404 [33] (Leviton 4 Button Switch)> received Z-Wave command: {args={dimming_duration="default", scene_id=5}, cmd_class="SCENE_ACTIVATION", cmd_id="SET", dst_channels={}, encap="NONE", payload="\x05\xFF", src_channel=0, version=1}
and the old DTH format. Two parameters should be allowed: “dimming_duration” and “scene_id”.
Looked for a definitive reference on the Z-WAVE Command format on the web with no luck. This was the best that I could find: https://z-wave.me/manual/z-way/Command_Class_Reference.html#SECTION0016330000000000000000
Thanks
