Question about TP-Link Deco E4 WLAN Mesh 2-pack Set (AC1200)

Hello Community I have pulled LAN cables, installed a server cabinet with modem and switch in the basement and would now like to connect 2 TP-Links (one per floor) to it in order to have a total of 1 WLAN. I would like to connect both TP-Links to my RJ45 sockets using LAN cables. I assume that I have to operate the TP-Links as access points, right? The TP-Link on the upper floor is in the bathroom. The power connection there can be switched on and off using a button. When I go to bed, I use it to switch off the WLAN on the upper floor. That's the reason why I want to connect both TP-Links to a LAN cable. The TP-Link on the lower floor can/should always radiate. What do you think, will my plan work with these TP-Links? Thank you for your valuable feedback!
