Hi everyone,  
I’m currently planning a small but functional home network and would really appreciate some guidance from more experienced folks.

My goal is to run up to **3 access points via LAN backhaul** (see sketch). For now, I’ll keep using my existing **4G router**, which I might switch into **bridge mode** later if needed.

I’ve been looking into **TP-Link Omada**, but I’m a bit confused about the required setup. From what I understand, I might need:

* Gateway (e.g. ER605)
* PoE Switch (e.g. ES205GP)
* Hardware controller (OC200/OC220)
* Access Points (EAP683UR / EAP673)

What I don’t fully understand is:

* Why is a dedicated gateway (like the ER605) necessary?
* Do I really need all of these components, or can I simplify the setup?

I also checked the all-in-one options like the **ER7212PC**, but they seem to be out of stock. The newer “Fusion” gateways also appear to still require an additional PoE switch (if I understood correctly).

So my main questions are:

1. What would be the recommended Omada setup for my use case?
2. Which components are actually necessary vs. optional?

Thanks a lot in advance — feel free to reply in English or German, I appreciate any help! 🙂
