Z-Wave JS + Fibaro Keyfob FGKF-601

You might have tried this already, but since you didn’t write anything about it I’m mentioning it.
In Z-Wave JS the event for scenes are now in a new event “zwave_js_event”.
I assume you want to listen for scene changes on the Keyfob and use it in an automation. You should be able to find what you need under Events if you listen for “wave_js_event”.
