No, read the thread posted above
there is no version 4 hub or equivalent mentioned, Aeotec hub is just a rebranded ST hub. Aeotec doesn’t sell zigbee devices.
The correct section is devices because so far nothing has indicated that Samsung is dropping the SmartThings name or platform. Just shifting away from hardware. See the discussion in the threads linked to.
