Hi Scott,
Thanks for the tip. I was wondering this too. I will have to read up on association command classes as well.
With regard to how well the GE/Jasco Z-Wave Plus In-Wall Smart Motion Sensor Switch (26931/ZW4006) work, I’d say they work well. I have them set to high motion sensitivity, and there’s only a slight delay (less than a second) before it turns the light fixture on. The switch has other features too such as a photocell (I disabled this) and a choice of manual/occupancy/vacancy modes. (I have it set to occupancy).
GE/Jasco makes a couple of varieties of the switch. You can see them here - https://byjasco.com/products/category/home-automation/z-wave-home-automation. I probably should have gotten a paddle style dimmer. Alas, I didn’t research the my project well.
Regards,
Burzin
