How to VLAN iot? (alien.top)

Hello, this is not a question on how to configure my router (maybe) it's more for the concept that I can't understand.

By the way, I only have a default isp router, that I can't even modify the dns, so I assume I'll have to buy my own.

So o want to have all my IOT devices on a different network, so as to not compromise my newly made homeserver, but what I don't get is how will I be able to turn on and off my light bulbs.

All the articles I see on creating VLANs tell something like "devices on port 2 can communicate with port 1 (internet) but cannot communicate with devices on port 3,4,5, 6..." and so on.

But if my IOTs are on a VLAN A and my Phone, computers, server are on VLAN B, how can I turn the lights on and off from my phone?

Maybe I'm getting it wrong, and my phone should also be on the same VLAN as the IOT, but then how will I connect to my server?

Thanks.

i aint no expert but i have separate VLANs for my phones & pcs and a separate one for IOTs.

I noticed most IOTs do not just communicate locally, but also via internet. So even on separate VLANs, as long as they are all connected to internet, they will work. My Meross smart plugs, garage doors and a TP Link light bulb work this way.

Just make sure you research in advance for your IOTs. Things like a Chromecast, Apple TV and a printer like to be on the same network as your controlling device like your phone.

As long as you are able to deal with mDNS (either allowing broadcast through VLAN, or with reflector), your Chromecast and/or Apple TV can be on a separate network without problem.
