Please log in for more thread options Leviton's Vizia RF systems are Z-Wave. One advanage there is that they are compatible with all of the other Z-Wave systems on the market. There are over 100 manufacturers selling or developing Z-Wave hardware already. > I'm replacing all my old X10 stuff (too flaky).

Z-Wave is reliable. Although one poster who has not used it claims otherwise, the stuff can handle a very large home if done right. Leviton also makes X10 compatible units though I prefer the RF. > These things are very expensive ($70-$80+)

Here are mine: I have done two ViziaRF installs to date. One large and one medium. Several others are planned in the near future. Installation is no harder than X10 or any other retrofit. You will curse the electrician with some regularity due to box size. Any of the HA switches are quite a bit larger than standard ones and box space will be tight. That said, I have always been able to make things fit...eventually. The ViziaRF switches rock in terms of feel and ease of install and come with a 5 year warranty. High WAF on the Vizia as well. They follow Lutron and other high end lighting in terms of form factor. Its also being pushed as the preferred format for the elderly. I have not used other brands enough to comment on them. I am yet to find a range/hops issue, even in the large installation. I have not done formal tests, but my current attitude is that it is good enough up through the 3500 sqft range/single story, depending on layout. Homeseer offers a tool that does Z-wave network analysis which would help with any network issues.. It requires their Z-troller primary controller. Same goes for signal interference. I have set Homeseer to poll regularly and it logs any devices that does not respond. A subset of the nodes show up randomly and I can not tie it to household activity. However, they all respond to polls. For now its seems to be network transients, and they are not impacting performance. The closed loop feedback is great, especially for anyone coming from . Even the low cost Intermatic HA09 give an indication in case of command failure. While there are other PC products out there, Richard Helmke still sets a high standard for customer service and support. His efforts with the rollout of the Leviton Zone and Wall controllers were exemplary. I have not yet integrated Z-wave with either with HAI or Elk. I used Homeseer with the larger installation, and no central controller (other than the Z-wave primary remote) on the other. The interchangeability is OK, but not perfect. There are still wrinkles in a few areas. Creating heterogeneous secondary controllers is a case in point.. Typical under the circumstances, but better than I thought I would find. Cynic that I am, I was pleasantly surprised about the overall interoperability I have found. Asymmetric control is my big whine at the moment. Nothing out there that addresses that yet. It can sort of be done by Homeseer, but the limitation is fundamentally existing Z-wave hardware. I am annoyed enough by it to consider hybriding a system with UPB or even X-10 to get around it. The new wall controller from Intermatic may. Its in beta, and I have asked to join that effort. Other manufacturers appear to be interested in that functionality as well.. There are other product areas I would like to see filled. Fan speed controller is one, fixture modules, and outlets (there is one promised from Intermatic real-soon-now) also come to mind. A wall controller with single switch functionality would also be very useful. My thoughts as of tonight. Dan Wright Starwolf Systems | ||||

> What's the distance between nodes? Does Vizia use 4 max hops? ViziaRF says it use up to 4 hops. Roughly the longest distance between nodes is about 25 feet. Furthest node from the primary controller is about 65 feet. | ||||

I think the real point is that in applications such as yours the standard (4 hop) Z-Wave system is quite capable. Obviously, each home is different and one 3,500 sf home might be more difficult to accommodate than another. Some have claimed without ever having seen it, much less tested it, that Z-Wave cannot handle larger homes at all. It does the newsgroup a service to post real world experience with Z-Wave and competing technologies. -- Regards, Robert L Bass =============================>
