So I figured now would the time to pick up some Z-Wave deadbolts, but as far as I can tell none of them support S2 security.
Even devices newly certified as recently as 11/10/2017 do not support S2.
What's the real scoop on S2 security? The attacks on older Z-Wave were devastating but I thought they were addressing the security concerns effectively. I haven't been able to find much talk about this online.
