I have maybe 35 ge z-wave switches. Put them in over a year ago and work great. I just changed out from the default device handler to custom (to custom) to allow double tap. This is great for quickly increasing dimmers to 100% or turning off a whole room. I would recommend this. Inovelli people, I am thinking of getting a few of these, I read about the delay when you turn on your switch. Do you see this despite programing it to zero? I like the LED alert and would like a few scattered to tell me if the doors are unlocked, garage door open, etc.
