Thanks. Looks like Kwikset has a new design, but assume the technology in this has not changed? Anyway, want to understand the options for integration with HAI/Leviton. From reading the thread, it looks like Leviton will be updated their Serial Interface Module to work with Kwikset devices. If so, I guess I could go ahead and purchase the Kwikset devices (and use them manually for now) and integrate them later? SJ
