If the sensors are not being added to your account, even as a “thing“, than that’s a different problem than the whole edge driver issue. It’s more likely that either the sensors themselves need to be reset or that they are a particular model which is for some reason not compatible with the Zigbee profile that smartthings uses. Assuming, of course, that you have other Zigbee devices that are working with that hub.
If you don’t have other Zigbee devices already working, then the first step is to make sure that the hub itself is up and functional. You can use the API browser plus website for that. 
If you checked the wiki per my instructions, you should’ve gone to the edge Driver page, and the only things you would find there would be edge drivers. Not old groovy DTHs.
This page, and then check the list for Sensors:
FAQ: Using the quick browse lists without the community wiki
That in turn would lead you to the following community-created edge Driver, which does have fingerprints for at least two versions of that model number.
However, the edge driver won’t help you if the device is not adding to your network at all. So that’s why we need to back up a step to make sure that it actually can be added if only as a generic “thing.”
