What ports in general does HA use to discover devices?

I have all of my IoT devices in their own vlan/subnet. I use Unifi to manage my whole network.

I’m just setting up Home Assistant for the first time (VM running on an XCP-NG host). It runs inside my standard network. I need to allow ports from its IP to my iot vlan, but I do not know what ports are used to discover devices (all are either tp-link kasa and Wyze devices).

What ports should I allow between my iot and my HA vm?
