Connect device to specific interface in wireless network

Hello,
This is a screenshot of my wireless interface with SSID BE.MY.GUEST

I've configured it to use interfaces 'guest_interface' and 'media_interface'. Both these interfaces are VLANs with different IP subnets. How can I control which IP address a device gets based on the MAC address?
For instance I just want my TV to connect to the media_interface instead of the guest_interface. I tried to set a static IP for the TV (which would be part of the media_interface), but the TV keeps getting assigned a guest_interface IP address when I connect to BE.MY.GUEST. How can I fix this?

Any help is much appreciated.

You assing an ssid to just one network

You can make another ssid for the other network
