The Z-wave products that are available are rather costly considering what they are. Z-wave is just another home automation protocol, it really has not grown to be dominate, (yet). I asked that question in a design class, it's proprietary, it has lic fees to develop products and has up to now, rather low market penetration. The transceiver module is set to 1mw / 0db on it's ISM Band. The FCC here in the states are cracking down on routers (2.4 and 5Ghz) because of the open source projects such as DD WRT and others as people were in the code, changing it and having the transmit/receive power/sensitivity exceed the FCC mandate for those ISM bands. Now the newer routers have the firmware locked out so there is no playing with the calibration coding. Same could have been done with the Z-Wave modules and the Open Z-Wave Project (and other open source coding). This may be why you are suddenly faced with Sigma Design only and the special equip to program the chip. Certification of each chip would than be in order. Than the firmware would be locked down per the FCC request. Z-Wave may not be the only way to go. Since Google and Honeywell have settled thier disputes and NXP and Thread protocol (Google) are in the final stages with and NDA in place, the future may hold something different than Z-Wave. Within a few months you may hear about the release. Subscribe to NXP (NXPI) RSS or Newsletter. For the time being, if you want the Z-Wave your stuck with what you are doing. I wonder if that whole Z-Wave will go the way like X10 etc.Thanks on the info.

Should do for now
