Great Job Buddy
I am testing with mikrotik radius and works well.
Mi Hassio validate for command line. I can manage with mikrtok userman the users and password
Thanks for your job!!!!!

I'm glad it helped. :)

What do you do with the requirements.txt file?

Install the requirements: pip install -r requirements.txt.

How can I setup hassio to do this on startup? I'm using it in a Docker container so it has to be reinstalled when the container restarts

You should plug in somewhere at the entry point script or prepare your image.

Hi, i'm trying to differentiate HA trigger between A, P, S and D / H status in Hotspot > Hosts status.
The reason for this is that there's some clients that only connects and not logged in to my hotspot server, and that messes up the automation. My AP is unifi and my radius server and hotspot server is mikrotik. Currently using unifi counter as trigger but of course i'm getting alot of false positive trigger due to above issue

Can this be done with your script?
How would i create a sensor then?

Hi, I tried to install your scripts.

I'm running HA os on ODROID. At first I installed python3.
I installed radius with pip command (not with the requirement file).

However when I try to login, I get a ivalid username error.
In HA log I see a Permission denied error on the radius-auth-sh file.

What can I do to fix this?

Is there any way for users not to be administrators?

Is there any way for users not to be administrators?

It's an authentication script. Probably you can attach roles to users afterwards.

Hi, do you have any plan to make this as custom component in HACS? It would be much easier to install requirements and use your awesome code :)
