Sensative Strips Guard 700 (11 01 021) "Unknown Device" in in OH2.5 (Openhab 2.5.8-1)

The general process to add an XML (download from the Z-wave DB) to a jar in OH2 is here. IIRC the Z-wave jar in 2.5 is in your addons folder. I don’t know about your jsondb idea. I think just waking the device after the updated jar is in place will work, but not sure on that. You could try that before excluding/redadding.
