May I ask which switch you would recommend for me? without POE?
What do you need to pay attention to with the switch?
Which system do you want to use now? That will also depend on a bit. If you are going with Unifi, a Unifi switch would also make sense in order to integrate it into the controller. With your 12 ports in the house, the Switch Lite 16 PoE would then make sense (with PoE, because if you go with Unifi, you will of course take the PoE-powered APs from Unifi as well).
The big question with the switch is whether it should be managed or unmanaged, and whether Layer 2 or Layer 3 is needed. The recommended one is Layer 2 and that should be sufficient.
