Hello, im a total noob, how do i use this? Thank you

@pawnedprawn I updated the markdown file. Let me know if you need more details.

Thank you very much for replying. Where do I begin? This will be helpful for me since the modem is far from my home.

First, ensure your model is compatible by checking https://github.com/Salamek/huawei-lte-api#tested-on.
Then, ensure you have a local network access to your router.
Follow guidance at https://www.192-168-1-1-ip.co/huawei/routers/789/ to check you can connect to the administration panel.
Next, install the python dependencies on the box that will execute this script and set environment variables.
Finally, launch the script.

Hi @aslafy-z!
My routers compatible and I have access to the admin panel but I am also a total noob and not sure how to install the “python dependencies”. I’d like to learn but could you point me in the right direction? Can this be installed directly on the router? Normally I’d just trial and error until I figure it out but don’t want to brick it! Thanks for any help.
