Add support for TP-Link ER605

[leetNightshade]

I have a multi-wan TP-Link ER605 Omada Router that I would love to integrate into Home Assistant. While this is an Omada router, I'm not using an Omada controller, so I can't use the TP-Link Omada integration. I would love to use the TP-Link Router integratio, which I believe is what this repo is for.

This router has a username and password entry, so I'm not sure why there's a single password field with the HA integration. Also I use https://192.168.64.1, so it resetting the default back to http://192.168.0.1 is annoying.

Here's what HA TP-Link Router spits back at me:

Try to use web encrypted password instead. Check the documentation! TplinkRouter - C1200 - TplinkC1200Router - Unknown error for pwd! Error - Expecting value: line 1 column 1 (char 0); Response - <h1>Not Found</h1>

I'm creating this issue to throw it out there I'd love for someone to add support for this particular TP-Link router.

I imagine you'll tell me to add the support myself, but maybe you can help nudge me in the right direction if you don't think it'll take to long. 🙏

You know, maybe I opened this ticket up on the wrong repo. I'm probably looking for the HA repo, not this python package. OH wait, you say here to create tickets on this package, so I am in the right place.
