@Ske19 I replied to your other post in the forum in regards to obtaining a Welcome code. 
Once you get the hub back up and running and still encounter the z-wave issue, simply post details (brand/model) on the z-wave device that is not working. Use the following community developed tool for locating info on the device. Find the device, tap on details and take a screenshot of the section and post it with the other info noted above. https://community.smartthings.com/t/smartthings-api-browser-now-available-to-all/249907
Someone on the forum will offer assistance.
and yes, resetting the hub was probably overkill because you may still experience the same issue once you get the hub back up and working.
