Emersonvier, you should use a newer DH for those devices. I’ve added Gavin’s endpoint change for the door sensor and I’ve added an endpoint for the button to my version. This will make Smartthings detect the device once it’s paired (do the hold to reset, wait for blue light to blink repeatedly, wait until it blinks again after a short period, if you don’t see three blinks, press again until it either blinks once for not paired, or three times for paired). Once the device light blinks 3 times to indicate it’s paired, wait 10-20 seconds and the Thing should show up properly in the app.
I have mine here (I’ve updated my version of door sensor and button):
ArstenA also has his:

Gavin has his (for the door/window sensor):
