Vlan on TP-LINK TL-SG105E

Hello. before writing here i read similar carefully. However, I recently saw an opportunity (?) to make a VLAN for IoT not for cosmic money and I want to make sure if this is really the case. I will be grateful for your help.

So what do we have now?

  1. tp-link deco e4, as a router and the basis of everything. IoT devices (Tuya) hang in the guest network.

  2. So far, a useless Raspbery Pi 4 with HA already installed, which is waiting for the lucky moment to connect to the network.

  3. A redundant Asus rt-ac1200g+ ready to take on the heavy lifting of IoT

  4. A home NAS that wants to be in the home network and not have to deal with IoT

And this whole set has no built-in VLAN capabilities. I have no money for Cisco Layer-3. But I see a budget switch TP-LINK TL-SG105E on the market, which has such an opportunity.

THE QUESTION. Will the following flow work:

Internet →
tp-link deco e4 distributes wifi for the home network and connects via LAN to →
TP-LINK TL-SG105E , on which to make VLAN 1 and VLAN2 →
connect Asus rt-ac1200g+ to VLAN1 and distribute IoT WiFi through it - >
connect the NAS to VLAN2


Does this make sense, will the home network be protected?

Thank you
