Looking at my timestamps, 44 zwave plus devices took 8 minutes to heal.

On OZW, it was about 25.

Anyway, thanks again for looking into this one and seriously thank you for creating such an awesome project.

This seems to be a persistent problem with those locks. They request a nonce (number used once) twice in quick succession, the second request invalidates the first nonce and then they use the first nonce twice, also in quick succession.

Unfortunately, this is nothing we can fix or work around without breaking compliance with the Z-Wave specs.

Unless you included the lock with zwave-js, you could try and reset, then re-include the device to see if that changes its behavior.
