zigbee???

From: George on 15 May 2010 11:10 We have a requirement for remote (on/off) I/O that seems like a good fit for a Zigbee-ish system. What I've found is not what I expected - there seem to be a number of IC/module-level devices (of variious levels of integration), but no off-the-shelf board/box-type products. (eg - an '8-bit Zigbee input board'.) So, if there are such products, I'd appreciate a pointer. If not, we can roll our own. But, does the (apparent) dearth of such things say anything about the future of Zigbee? Are ppl just integrating it into proprietry stuff, or has it failed to catch on? Or something else?

Like usual. A success is only possible if two things happen and this appears not to be understood by the management of HA companies: a. Reasonable pricing b. Availability at Home Depot, Lowes, et cetera. I deal with RF quite a bit. What I see is that companies generally roll their own 433MHz, 910MHz or 2.45Ghz stuff. When you get into qties of several thousand the pre-certed modules are just too expensive. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

When designing I don't really need that and $500 just for home automation will raise a flag with SWMBO, just like a $500 handbag would with me :-) What body public needs is reliable and UL-certed modules to replace light switches, that unlike X10 _are_ CFL-compatible, and that preferably don't cost more than the magic barrier of $19.99 plus tax at the hardware store. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
