Hi guys, and thanks for the good information on Z-wave. There is one item that I am having trouble understanding. The Radio specifics section says:
Z-wave units can be in power-save mode and only be active 0.1% of the time, thus reducing power consumption dramatically.
But then the Topology section says:
In order for Z-wave units to be able to route unsolicited messages, they cannot be in sleep mode.
So even though the protocol allows for sleep mode, sleep mode is not used in actual products. Is this correct? Perhaps a clarification of this point would be useful.
Thanks again!
Regarding range, the article includes this line:
"Range: Approx. 100 feet (30 meters indoors) assuming "open air" conditions, with greatly reduced range in normal situations."
So the range is 100 feet assuming "open air" conditions, and "30 meters indoors". But 100 feet is approximately 30 metres and the indoor range should be considerably less than the open air range, so this doesn't make sense.
This is also not good style. The text in parenthesis should be either a translation into metric, or a statement of the range indoors vs. outdoors. It shouldn't be both.
I will edit the article to remove this contradiction, but someone who knows more than my about this topic should fill in the indoor range.
There should probably be a Z-Wave versus ZigBee comparison section. They both begin with the letter 'Z' and people may think they are one and the same, or Z-Wave a derivative of ZigBee, which doesn't seem to be the case. -- Ray ( talk) 13:48, 12 December 2007 (UTC)
I would like to see an article/list of products that implement Z-Wave, maybe manufacturer link. Or is this Googles job? —Preceding unsigned comment added by 193.15.240.60 ( talk) 09:08, 20 December 2007 (UTC)
I have tried several times to change the Z-Wave link to the official Z-Wave.com website, but it seams like someone changes it back to z-wave.ru as soon as i have changed it. The official site is Z-Wave.com please leave the link as it is. —Preceding unsigned comment added by 69.95.44.86 ( talk) 00:07, 5 May 2008 (UTC)
I've added and named several references that can be used to support more statements within the article. They're are
I've done this for the regulars that contribute to the article. I'm off on a new mission :)

I think these contributions would balance the article and help others like myself. Disclosure, I'm just an interested consumer and have no ties to any home automation companies. -- Rob Terzi ( talk) 15:48, 21 March 2009 (UTC)
I can see at least 2 major problems on the way to world-wide protocol adoption: 1) Undocumented protocols are basically bad things, just as any other kind of vendor lock-ins. 2) Sub-gigahertz frequency usage may put consumers into troubles and harm technology adoption. Usually, sub-gigahertz frequencies are already tightly occupied and their usage is prohibited or restricted and may require consumer to obtain license for given frequency, this costs moneys and takes some time and efforts, or licensing could be denied if other important services (like army, emergency, transportation, television, etc) are already using desired frequency band. Therefore I can see it as DISADVANTAGE vs 2.4GHz based systems if I'm going to deploy home automation system. 2.4GHz systems could be just installed without administrative hassle in most parts of world and this is their strong competitive advantage. —Preceding unsigned comment added by 195.210.145.118 ( talk) 17:05, 6 April 2009 (UTC)
In section Setting up a Z-Wave network: "key-fob controllers". Couldn't it be interpreted as a controller that controls a key fob? Isn't it just key fobs? -- Mortense ( talk) 19:31, 26 February 2011 (UTC)
Confusing, yes, but for a reason. In the Z-Wave world the word "controllers" refers to devices that are the "general" or "traffic cop" of the network. As strange as it seems, most battery powered remotes, be they key-fobs or "TV remote" looking devices usually are programmed to act as network controllers. FYI, there can be more than one controller in the network. The way to parse "key-fob controllers" would be a Z-Wave network controller device that has the form factor of a key-fob. All of that said, yes a little word smithing would help the article. Mountainlogic ( talk) 22:05, 16 February 2012 (UTC)
The section that sounded like an advertisement in 2008 is gone. I'd just remove the tag myself, but I don't like to do that while I'm not logged in. -- 50.133.131.206 ( talk) 16:34, 4 December 2012 (UTC)
I think that a section on security would be appropriate. I was checking G.9959 and could not find anything about authentication of nodes and encryption of data. How is that done? To me it looks like the technology is very unsecure? Can somebody comment?

Security: "Z-Wave is based on a proprietary design and a sole chip vendor."
Anyone a citation? Otherwise I'll delete that sentence.
