Have you set it up? And can it work now?

Still can't make it work :(

You can contact the supporter directly for help.

Having a problem connecting to tp-link to access the manual. But that seems to be a simple layer 2 smart switch, seems you even have to run software on your windows machine to manage it, no cli or web gui that I can tell.
So unless it supports intervlan routing, layer 3 your going to need something else to route between your segments be it vlan tagged or port based or actual just physical segments.
Just because you have a switch that supports vlan tags or native port based -- you will now need something to route the traffic between your segments. What router do you have? Can it run 3rd party firmware? Many soho home routers do not have the ability to route between segments or even support vlans on the lan interfaces, etc. Many you could turn nat off and just use them as routers, where the wan in is one segment and the lan interfaces are in another.. So if you have another router laying around you could use that to route between your segments, etc.
I agree with segmentation of your network, especially if you can then firewall between the segments - but that switch doesn't seem like it will be able to do what you want on its own. Once I can get hold of the manual will know for sure.
Ok got the manual finally - yeah your going to need something else to route.
