In order to plan the replacement…My current ADT/Smartthings Hub is working like a Swiss clock …
maybe, but dont count on support.
Okey my friend, you are right, I bet about ADT/Smartthings hub and is working great, but Smartthings New App is lacking of some smartapps, anyway I have gone around this (automations and Sharptools) and I have made a really comfortable home system, Im searching if I could bet for it again knowing no support at all, but maybe getting same result than the ADT/ST one…working fine…
Don’t worry that much, i live in Cyprus and it works just fine. Just don’t expect much from support… 
Hi my friend, I had noticed that WiFi/Hub device type is not listed inside Aeotec Brand in the Smartthings New App, so I wonder how did you added your Aeotec Smartthings Hub ?
try adding it as a SmartThings hub model IM6001-V3p (listed under the SmartThings brand in the app).
