Discover devices in VLAN (self.homeassistant)

I've a VLAN dedicated to IoT devices and, of course, HA can't discover them. Is it possible have them discovered by HA via MQTT? Create them manually it's a pita because they're a lot and I would have to create sensors/switches + battery level + RSSI Thanks!

is there a reason you can’t put your HA in that VLAN too? if it’s a segregated, non-networked environment then why not create a second network adapter for your HA and give it an address in that VLAN too?

I've added an extra NIC that is in the IoT VLAN, but there are no new devices. The NIC is ok, because I see that it gets the IP from the router. What can I check/run?

can you ping one of the IoT devices from the HA device on that new NIC?

can you manually add a device and HA see it/add it normally?

is there a firewall routing between HA and the IoT devices that might be blocking discovery somehow?

I can ping the devices. No firewall, the NIC is directly in the VLAN and the Proxmox firewall is off. How can I add a device manually? ...I'm just starting with HA.
