Lyndel, thanks for the reminder. You made it easy for me to find the right thread

I hadn't searched before because I didn't know which words to search for.

But you're wrong about "extended RC6". Streamzap is an extended form of RC5 not RC6. There is no chance that the streamzap signals will work this device. The best shot is for someone to do to this protocol what Eigeny did for Streamzap in that thread.
