Thank you, then I will share this request with our site manager tomorrow: Deep flush-mounted box, at the spot where the electrician is supposed to pull the network cable later. Unfortunately, the basement ceiling is already installed. I will ask if at least a bit of concrete can be chiseled away around the empty conduit so that the keystone module can be hidden there. It's somehow a pity that Unifi doesn't offer taller spacing rings for this case. My gut feeling tells me that it will be either NanoHDs or the 6 Lites. I haven't read up on that yet. So far, my approach has been: What is network? -> Can I do it myself? -> Where do I need it? -> What needs to be discussed with the electrician? -> Components? The request to the site manager is fine like this, right? How would you deal with the network cable from the ceiling, which already doesn't have a flush-mounted box?
