Honeywell T6 Pro Z-Wave Thermostat: Security S2

I’m checking if my z-wave thermostat can be securely included using the z-wave binding. According to chris jackson’s database for the device, security is not available:

However, the tech sheet states S2 unauthenticated (not sure what that is) security is supported:

I know the current z-wave binding does not support S2 (yet), but according to chris, all S2 devices support S0:

So should the device definition in the database be updated to support security?

openHAB 2.5.6 Release Build
ubuntu on Dell Inspiron 7773
Z-Wave 2.5.0 SNAPSHOT
Aeotec Z-Stick Gen5
TH6320ZW T6 Pro Z-Wave Programmable Thermostat

Please feel free to update the database if there’s an error - it would certainly be appreciated. However, this will not change anything if you are having a problem joining securely.
