"Based on the current generation Z-Wave protocol, Z-Wave Transceivers (Devices) cannot broadcast or send status update changes back to any handheld or automation controller with the exception of a confirmation reply to a controller that just issued a command to change. Equally important, if a device (light switch, etc.) is manually operated it does not broadcast any status change at all. The obvious issues are that automation interfaces such as the Elk-M1XZW, including Elk Keypads, and Elk's Virtual Keypad software cannot remain in sync with the true state of Z-Wave devices if their state is not broadcast or available. This is not unique to Elk. Other manufacturers of ZWave controllers face the same dilemma. One might think that a periodic polling command for status would provide a solution. However, the poll intervals and the potential detrimental loading effect on the radio network is uncertain. Even with polling, there would still be a time lag during which displayed status would be out of sync. It is hoped that Z-Wave will some day add Status Broadcast to their protocol."
I haven't seen any discussion about this on the boards. Does anyone know if this will change soon?
Thanks
