Re: Help with 7 Circuit Project?



I'm not arguing semantics. I'm saying flat out that you do not seem to have
much knowledge of the topics you are expounding on.

The fact that UPB has been licensed to other manufacturers hasn't done
anything to lower the price. X-10 was also available from many
manufacturers. Did that make it better?

In this context, your 4 digit password is just as secure as 128-bit
encryption. Neither does a damn thing to prevent capture and playback of
codes. If "rdjy5roigdpb8gv" floats your boat, it will float your boat no
matter who sends it. Rolling codes are reasonably secure but are seldom used
for anything other than garage doors and for arming/disarming security
systems.

I'm surprised to learn that UPB systems need a paid professional to
troubleshoot them.
