boolean ZW_RequestStatus (int $InstanceID)
ID of the device
If the command succeeds, it returns TRUE, otherwise FALSE.
Queries the status from the device with the ID InstanceID. Only power-operated devices can be queried directly by command, because battery-operated devices do not permanently listen to the queries.
This function loads the radio traffic considerably.
It should be used only to upgrade critical equipment for the IP-Symcon start. A renewed queries at runtime is not required, because Z-Wave sends normally all status changes directly to IP Symcon. Older devices which refuse to do so, should be replaced with newer equipment.
