We find that there are three major limitations to RadioRA that are overcome by the HomeWorks Rf product. First is the 32 device limitation (which is increased to 64 with the Chronos system bridge allowing 2 systems in 1 install). Second, the user interface, both the keypads themselves (the micro buttons with the equally micro labels), and the keypad capabilities (Scene vs. Room mode only) can result in a less than intuitive operation. Third. decentralized programming (run around the house and press the buttons) is less than efficient and can't be saved or backed up. Add that to the fact that the pricing is similar, and its no contest ... For this group, the only "challenge" is that the product is not offered in an Over the Counter form, you need an integrator. For most clients, that's true anyway. BTW, the design of this product, coupled with an RS-232 to Ethernet bridge, would allow an offsite programmer to set up your system.
