Does every Z-Wave device have its own unique ID? If yes, can we read it from Z/IP gateway? I mean to ask this question on all Z-Wave devices not limited to those using Z-Wave 700 series.
I get the following answer from raised support case.
Each Z-Wave 700 series device itself contains a 64-bit device unique number stored in the read only Device Info page in Flash. For ZGM130S module, this number is used in current application examples with the Device Specific Report command, referring to the function: CC_ManufacturerSpecific_DeviceSpecificGet_handler() For Z-Wave 500 series devices, there is a configurable UUID field available in NVR Flash page, see SDS12467 500 Series Z-Wave Chip NVR Flash Page Contents, it can be programmed by Z-Wave Programmer, and is also used by the Device Specific Report command for 500 series application examples. Hence, Z/IP client can retrieve this number by sending Command Class Manufacturer Specific, Device Specific Get command if needed.
