The spec is constantly evolving. Last week they released more updates. It’s a continuous process.
Long story short, it will be an automatic update to the hub firmware. However two things to note:
- Any paired devices will need to be re paired to use the S2 standard, the mode is set while pairing
- Not all advanced features are used automatically with a firmware update. The advanced features depend on the DTH, for example this one is designed to support zwave plus features based on the lock model and will support additional features in future as applicable.
However S0 vs S2 should not impede any basic lock functionality and advanced features can always be addressed in DTH updates.
