This script just simplifies the bootstrap process of creating the r0kh and r1kh config options.
usage: helper.py [-h] [--ap AP] [--format {uci,config}] iface
positional arguments:
iface uci wifi iface index
you can obtain the uci index by looking for your ssid:
uci get wireless.@wifi-iface[0].ssid
uci get wireless.@wifi-iface[1].ssid
...
optional arguments:
-h, --help show this help message and exit
--ap AP bssid(s) of access point(s)
--format {uci,config}
output format
uci: prints uci commands (default)
config: prints config file snippets
So in case you do have 3 access points sharing a SSID all over your place (Notice that there should be only one DHCP server in the network. The APs must not provide their own subnets. (Thanks khmtambi for the tip.)), just collect their BSSIDs (In LUCI, go to "Network -> Wireless" and use the BSSID of the SSID you want to provide with roaming) plus the uci wifi index (see usage) and call the script like:
./helper.py 0 --ap 11:22:33:44:55:00 --ap 11:22:33:44:55:01 --ap 11:22:33:44:55:02
which renders some output with random mobility_domain and password for inter-ap radius sessions:

Apply your settings with 'wifi restart'
If you like to edit config files instead of uci commands, just change the format:
