Hi Thanks for sharing. I'm a developer but not familiar with flutter.
Is it intended for mobile platform or can it work everywhere?

Can you give me a brief explanation of the technical principle you used please?
At first glance, it seems that you are using an undocumented v2 API and searching information based on the MAC address in the link

Thanks in advance

  @tlt Hi, 
 

I based my API endpoints on the information found here:

https://community.tp-link.com/en/business/forum/topic/590430
In my case, I'm using V5.4.6.

Theoretically, this should also work on the web. You need to get the client's Wi-Fi MAC address or Wi-Fi IP.

  @tlt

Here are the API endpoints used.
Please note that you may not need endpoint #2 if you can obtain the Wi-Fi MAC address on your webpage. In that case, you can proceed to endpoint #3 directly.
Also, you will need to obtain these controller data to proceed in using the endpoints.

OMADA_URL="https://192.168.0.x:8043"
CONTROLLER_ID=""
SITE_ID=""
USERNAME=""
PASSWORD=""
 

1. Login Endpoint:

   • Method: POST
   • URL: '{omadaUrl}/{controllerId}/api/v2/login'
   • Purpose: Used to authenticate the user with the username and password, and obtain an authentication token (authToken).

2. Fetch Client Data (by IP):

   • Method: GET
   • URL: '{omadaUrl}/{controllerId}/api/v2/sites/{siteId}/clients?&token={authToken}&searchKey={wifiIp}&sorts.end=desc&filters.active=true&currentPage=1&currentPageSize=1'
   • Purpose: Retrieves the client data (such as MAC address) using the Wi-Fi IP address of the device.

3. Fetch Remaining Time (by MAC):

   • Method: GET
   • URL: '{omadaUrl}/{controllerId}/api/v2/hotspot/sites/{siteId}/clients?searchKey={mac}&sorts.end=desc&token={authToken}&currentPage=1&currentPageSize=1'
   • Purpose: Retrieves the remaining time of the user's session based on the client's MAC address.
      

  Thank you for the information. I appreciate it
