I know that the V3 hub is a spec downgrade from the V2 due to reduced memory and performance, as discussed in this thread.
However, I’m curious what other users real-world experience has been. Is it slow to respond?
I have about 45 devices. I’d hate to limit performance. However, I urgently need to have a setup running and Smartthings has completely screwed up my V2 hub with the recent mess, I have little confidence that they will fix it given the nonsensical responses I’ve gotten from Support (“first we’ve heard about the issue”, “reinstall the app”). Plus, I’d like to have Matter support going forward, but have Z-wave devices so can’t use a V4. Thanks for any feedback!
Given the low number of devices and the need for ZWave support the V3 should be fine. It will struggle if you start to load a larger number of devices. But overall performance is similar to the v2.
With the recent changes to the firmware and the upcoming changes to the drivers, the memory consumption should be cut in half. You shouldn’t have any issues anyway.
