Same here. With R072, if I say lock or unlock, about 1 out of 4 times, it would say timed out. Now it times out very rarely. However, as you said, while it locks within a sec or two, it takes a long time to send the response back. I am not sure if it is the problem with Kwikset or with Almond.
If anyone reading this has any other Z-wave lock (schlage, monoprice, yale), can you tell us how long it takes to lock/unlock and how long it takes to get the response back.
