The UniFi Controller
Ubiquiti's free software, the UniFi Controller, offers a UniFied platform to users for centrally managing their UniFi devices. Users can monitor, update, and configure their UniFi devices when installing the software on a computer. It is the centralized nerve center for controlling network settings, tracking device performance, and implementing changes.
Exploring UniFi Controller Options
Self-hosted UniFi controller
This option is more common in homes or small setups. Here, internet connectivity navigates through a firewall, a switch, and finally to the access points and other UniFi devices.
Users generally install UniFi locally on their computer, which works fine for some use cases. The problem is that the Controller will only be online when the computer is, and how do you make sure that all the advised ports are open without compromising your computer?
