Any tips to share? I tried to do something similar but failed.

My router has a backup/restore feature with an encrypted export, I figured I could use that to control or at least inspect all of its state, but I/codex could not figure out the encryption.

It's on my long list of projects "to-opensource" (but I need to figure out licensing, for those things CC-BY-SA I think is the way to go), I don't want a random lawyer sitting on my ass though.

I started with a simple assumption: if I can access the router via web-browser, then I can also automate that. From that the proof-of-concept was headless Chrome in Docker and AI-directed code (code written via LLM, not using it all the time) that uses Selenium to navigate the code. This worked, but it internally hurt me to run 300MiB browser just to access like 200B of metrics every 10s or so. So from there we (me + codex) worked together towards reverse engineering their minimised JS and their funky encryption scheme, and it eventually worked (in the end it's just OpenSSL with some useless paddings here or there). Give it a shot, it's a fun day adventure. :)

Edit: that's the end result (kinda, I have whole infra around it, and another story with WiFi extender with another semi-broken different encryption scheme from the same provider) - https://imgur.com/a/VGbNmBp

You should give codex access to the mobile app :) The app, for a lot of routers, connects via an ssh tunnel to UDP/TCP sockets on the router. Would probably give you access to more data/control.

Made a comment up above, but that's tdpServer and tmpServer (sometimes tdpd and tmpd) and it's what I use in my python implementation of tmpcli, the (somewhat broken) client binary on some TP-Link devices.

You're correct, it gives you access to everything the Tether app can do.

		I had been trying to find that again! It was instrumental in some RE/VR I did last year on tmp and the differences between the UDP socket (available without auth) and the TCP socket. Thanks for making that. I can't remember the details of the scheme, but it also allows you to authenticate using your TPLink cloud credential. If my memory is correct, the username is md5(tplink_account_email) and the password is the cloud account password. If you care, I can find my notes on that to confirm.

I had fun “hacking” my router that turned out to be just unzipping the file with slight binary modifications, it was so simple in fact I just implemented it in a few lines of js, even works in the browser :-D
