Repeated Switch status and event trigger lag

@Rich, I posted a day or so ago about similar activity with my Leviton switches but only after updating the firmware to version 1.2 from 1.13. Thanks for posting your findings. Does anyone know if there is any functional difference between the smart and non-smart version of the Generic Z-wave dimmer.

Looking around to find out the difference between the smart driver and the non-smart driver, from this post: Built in "Z-Wave Generic Dimmer" vs "ZWave Generic Smart Dimmer") and this post: Zwave smart switch and dimmer fingerprints it seems the non-smart driver won't allow the device to report it's status to the hub after a physical on/off? Definitely not ideal. What are the chances the smart driver can be updated to fix these issues?

I've also come across this non-built in App Driver code for leviton switches but I don't have any experience with using custom drivers and am a little hesitant to try it out.

I wonder if @mike.maxwell can help?
