Vizia RF seems to be similar to Cooper Aspire RF which has a driver posted on RTI's dealer web page. The notes for this driver say the dimmers and switches only provide unsolicited status feedback when in direct RF range of the RS232 interface. In other words, other Z-wave switches won't repeat the unsolicited feedback so that it reaches the final destination (being the RS232 interface). This is a significant limitation. Does anyone know if Vizia RF has the same limitation?
