Just chiming in on an old topic, but Ubiquiti has gotten a lot better and added a controller device "Cloud Key" to simplify long-term setup. Previously, you had to keep up with the computer where you set up the software, and if something happened to it, you'd have to reset and re-adopt everything. Now you can set up a Cloud Key and sync it to a Unifi cloud account, which makes long-term management much better.
