Thanks for your comments.
As you know, many companies affirm their technologies can't be consider as a "free of nocive EMI emissions". Nonetheless, My principal interest is to know which of this technologies is better.
I've seen a couple of companies which work with different standarts like HAI with UBP, typicall X10, Zwave of Zensys and Zigbee.
But what do you think? Which of these technologies are better?. I know X10 has a reliability of 70-80% and UBP has almost a 100% but It's a kind of expensive as X10, but better in problems of coupling and free collisions.
Let me know what you think. Thanks.
