Hey

 

Hopefully some answers for you below

 

1. I choose the EAP-Wall because the cost of setting up RJ47 ports is the same as buying the EAP-WAll, so i figured it will be easier and the added wifi is a plus. Is this fine?

There is nothing wrong with that thinking at all :)

 

 

2. Is hosting the Omeda controller compulsory? I can run in  my True-Nas Scale if needed.

No its not compulsary, but I would STRONGLY recommend you implement a controller for the 4 APs otherwise its just a chunk of not connected WiFi.  You need the controller for roaming and steering etc..   You can host this yourself, or an OC200 is a very cheap controller!

 

 

3.  I also have Truenas Scale NAS (it will be probably connected to EAP235-Wall) for basic file and PLEX, nothing heavy, do you think my switch is enough? Any recommendations?

Most home users wont saturate 1gbps LAN ports, also the switch has 8gbps throughput so this should be more than enough for you.   Moving to 2.5 or 10gb switches adds MUCH more cost all round tbh.

 

 

 

4. Since ill be running 4 APs, how to deal with roaming and switching? Do I give the same SSIDs or give separate for each room?

This is the controllers job.  Power on the APs and setup the controller as you feel necessary.  I have multiple SSIDs on different VLANs (IOT, HOME and CCTV) just cause i want different device types seperated but that is not necessary.  Most poeple go One SSID for all APs.   To do this in the controller setup the SSID as you require, then adopt the APs and they will start to broadcast the SSID automatically.   In terms of roaming and bandsteering.. recommend you enable both on the controller.      In short, ALL config is done via the controller and the APs will automatically adjust to suit that.

 

 

5. Any other improvement or recommendations on the AP or switch i choose, upgrade or downgrade recommendation.

If you are going APs and Switch, might be good going full hog and getting the Router also.  That way you can run VLANs if you decide to go that way, also the new controller is bringing in IPS (intrustion protection system) which is cool but will require a router (likely).

 

 

6. If omeda controller is compulsory and hosted on truenas scale, will my internet and network still work if the shutdown the omeda controller/NAS?

It will function on a basic level.   However 100% recommend this runs 24/7 as its designed to be powered on all the time.   If you are going to shut you NAS down a lot, better with an OC200 controller.
