I believe these are the same icontrol zigbee sensors as Xfinity Home, in which case they unfortunately use a proprietary zigbee which is not compatible with SmartThings.
But you can try resetting them and see if they’ll pair and then go from there. If you can look on the back of the sensor and give us the exact model number we might be able to say more. (The label might also be inside the battery compartment.)

(btw, as you can see from the open Home link above, the Yale door lock that Rogers uses is the zigbee model, not the zwave. Same case, different RF module. )
