Add Support for Archer A8(EU) Router device

[Gipssik]

I get TypeError every time I use some functions that are coroutines.

Configuration:

• Debian 11, WSL2
• Python 3.10.3
• tplink-cloud-api 4.1.3

Code:

import asyncio
import os

from dotenv import load_dotenv
from tplinkcloud import TPLinkDeviceManager
from tplinkcloud.device import TPLinkDevice

load_dotenv()
username = os.getenv("USERNAME")
password = os.getenv("PASSWORD")
device_manager = TPLinkDeviceManager(username, password)

async def main():
    device: TPLinkDevice = await device_manager.find_device("Archer A8")
    print(await device.toggle())

if __name__ == "__main__":
    asyncio.run(main())

Traceback:

UPD

I started to debug it and found some strange places and the cause of exception I guess.

request_data at line 53, file device.py looks strange:

And the cause of exception at line 36, file device_client.py:

@Gipssik what model of device are you trying to find? I wonder if this is an issue with compatibility of the library.

[Gipssik]

@piekstra I'm trying to find my router Archer A8(EU), it's connected to my Tether app. The library finds it and I can get its device_info

Ahhh that explains it. While this library works with the TP-Link API, it's currently only written to support certain TP-Link Kasa devices. At this time, any other devices are unlikely to be properly accessed via this library. To add support for your device would be a matter of reverse engineering the Tether app or monitoring its network requests and figuring out the API contracts since they are not officially documented.
