With the recent discussion of switch speeds in the Zigbee switch thread, It dawned on me to take a look at my LZW36. And I was bummed to see that parameter 50 is not on it. The 700ms delay is pretty slow to me. I have a few LZW31-SNs at 200ms delay and that seems decently responsive. And yes, I am using scene control on it, So I cant disable the delay.
It seems to me that Parameter 50&51 could be combined. 0ms is disable delay and scene, and the other increments for how fast you want based on how fast the user can multi tap. Just seems a bit redundant, but maybe its required based on other things.
