MRadius-Manager installs a Freeradius configured for use with Meraki devices on a Raspberry Pi (or any other Debian based system) as well as gives you a management UI.
The tool runs on a Laptop/PC with Python3 installed and connects to the Raspberry per ssh.
It is for Lab testings only (if no ISE is available) and the use is on your own risk.
