What home automation hardware should I use/avoid if I want it to be fast and reliable? Is anything connected directly to a PC's serial port (etc) OK? I would assume that this would work, with the tiny bandwidth needed for this. According to the web page though, HCS 2 modules are slooow ('several seconds on large networks') and unreliable, reading between the lines this is because they continuously poll all devices on a 9600bps net using a Z80. (Anything connected directly to the controller is OK, but most modules don't.) As the X-10 stuff is also slow and unreliable for doing more than switching devices on and off, this leaves me with CEBus (if I can find anything using it.) This is more reliable, but how fast is it? Also, has anyone got URLs where I can find more info about CEBus and available CEBus hardware? I couldn't find anything relevant on web searches, just PC interfaces. -- searle@longacre.demon.co.uk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
