OpenZwave do not support S2. Please switch to another zwave gateway.
I think you are in the wrong thread. However:
Openzwave is not a "gateway”.
Do you have a suggestion for an open source zwave library?
Why is this such a big issue? Do you have a Z-Wave device that doesn’t work without S2?
Instead, why don’t you help us at OpenZWave implement S2 instead?
