Without license, APs are still showing up with the flag L unlicense and AP will not transmit. No such thing as "home use" license, at minimum you need three- AP license (not sure if they sell 3-AP license, but I know they do sell one-AP license)
You can request trial license from Aruba SE, or I believe from HPE My Network Portal if you have an account.
After license your controller, you can try to use configuration wizard to setup simple PSK wireless network.
