Managing Ubiquiti home network remotely

One of the features of Unifi that I do like is using and being able to then ssh into any of the connected access points and use that terminal to remotely log in to the controller or the router. (in this case, remotely for a friend)

The controller is running on a RPi4 board, the router is a GL-MV1000 / Brume - GL.iNet.


Here’s what the setup looks like:

What are the alternatives to this? Especially since Ubiquiti hardware can be hard to come by now.
