For calibration purpose (temperatures…) I am looking for a unique and STABLE identifier which would uniquely identify a specific hardware sensor and NEVER vary through (un)pairing, sensor reset, hub change, handler update, etc…
Something like the MAC hardware address for the ST Hub, but this one attached to a specific Z-Wave Device paired to the ST Hub.
I tried the “device.id” which returns something like : “d4c9e5b2-ee20-4ffb-8134-8c3e8c73c00a”.
Unfortunately the “device.id” is stable ONLY until the device is unpaired/paired from its hub, then it returns a completely different identifier.
And I would very much prefer to use something unrelated to the display/log interface, ie NOT device.label, device.name nor device.displayName, since all those 3 could have to be modified in the future for display purpose.
Any suggestion ?
