1st it does work well. I would say that the wifi is only good up to 30' with RTI. So if you put AP's throughout the house you might be ok. Otherwise with wifi you cannot do cover art or anything that requires a lot of data. That's the "benefit" of zigbee. Both wifi and zigbee are pretty suspect with RTI right now. Some people (myself being one of them) have great experience with zigbee and being to use it up to 150 feet with no issues. Others have report no more than 20' with zigbee. Go to their website for details on how to hook zigbee. Basically it's one centrally located hardwired receiver and everything else acts as a repeater and only needs to be power. No interconnections between ZM-24's.
