how to use hikvision thermal camera temperature interval measure api with c#

Question

private async void StartServer()
{
    HttpListeningServer server = new HttpListeningServer("http://192.168.0.191:8080");

    await server.StatAsync(async request => 
    {
         switch (request.HttpMethod)
         {
              case "GET"
                  break
              case "POST"
                  using (var reader = new StreamReader(request.InputStream))
                  {
                       var bodyContent = await reader.ReadToEndAsync();
                       var xmlContentString = bodyContent.Split("--boundary").Where(x=>x != "").ToList();
                       var extractedContents = d[0].Split("\r\n").Where(x=>x != "").ToList()
                       string xmlString = string.Empty;
                       
                       for(int i = 3 i < extractedContents.Count; i++)
                       {
                            xmlString += "\r\n" + extractedContents[i];
                       }

                       var result = xmlHelper<EventNotificationAlert>.DeserializeFromXml(xmlString);
                  }
                  break;
         }
    }
}

Open the Http Server with the following ports and addresses "/ISAPI/Event/notification/httpHosts" registered the server address via API.

I succeeded in receiving events such as TMA, TMPA, etc. by referring to API documents, and now I'm about to receive a temperature interval measurement event.

"/ISAPI/Thermal/capabilities" api is normally displayed as true when determined whether the function is supported or not.

"/ISAPI/Thermal/channels/{channelId}/thermometry/realTimethermometry/rules" api was tried to check the current rule, but InvalidOperation returned as a result of API call. The same is true of requests sent to POST.

I thought I could get a temperature value every N seconds on a regular basis if I set it up.

Accessing Thermography data from a HikVision IP Camera

I also referred to the link above, but I was able to get the picture, but it didn't seem to be a way to get the temperature data.

If anyone has done this, please tell me what I misunderstand or missed

There was something I was missing about "/ISAPI/Thermal/channels/channelid/thermometry/senceId" from the above question. The actual price is different from the document I have.

The above result is the result of inquiring with ISAPI of my camera. However, the data differ from the examples of the resulting values provided by the "/ISAPI/Thermal/channels/channelId/thermometry/senceId/capabilities" api. The results of the API are as follows

As above, it should definitely contain a value for temperature, but it is provided without it.

It seems to be a problem that can be solved only by asking Hikvision for technical support. If anyone is still thinking about this question, thank you.
