Hi,

I'd like to parse out the OFF from the http response that look like this in a browser:

in the Browser's Inspector:

In WireShark:

And in code debugger:

The problem is that the delimiter is a paragraph sign.

I really need to know the current relay state, this is the latest code, I've been experimenting with:

public string GetRelayState(byte relay)
{
string api = $"http://{Ip}/api2.cgi?p={Password}";
var request = (HttpWebRequest)WebRequest.Create(api);
request.AllowAutoRedirect = false;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader s = new StreamReader(stream);
return s.ReadToEnd().Split('\u00a7')[2];
}

Could you please help me out?
