Hello. I've wanted to contact you with the e-mail but there isn't any information about you. I have some questions about your project presented in Blackhat 2014. That's are about the ZWAVE protocol. Firstly, I downloaded the grc(Zwave in grc) files from the 'bitbucket'. Is it just for the sniffing the Zwave pkts? It can do the TX like directly turning off the Zwave light? and Could I get the demo videos and the descriptions about it ? Thank you!
