krlaframboise himself has said in his Zooz double plug driver thread that there was no reason to use his after the built-in driver was added to Hubitat.
I used both his and the Hubitat driver and neither resolved my problems w/the plug, unfortunately. Mine had FW 2.0 and I had nothing but problems w/the plug, so having 2.0 is not a panacea...but you'd think should help.
