I wrote a code to control Nature Remo in C# because I saw the article about Sony DSC-QX10 that I wrote in the past. - 都内で働くSEの技術的なひとりごと / Technical soliloquy of System Engineer working in Tokyo

I bought Nature Remo mini on impulse.

Nature Remo is in simple box.

Nature Remo mini is a bit bigger than Airpods.

The cause of impulse buying is the following article. I wanted to control Nature Remo mini like Sony DSC-QX10.

I would like to operate Nature Remo mini with C # referring to the blog above and the Nature Remo API. Based on the following sources used in the operation of Sony DSC-QX10, I will change it to Nature Remo mini version.

static async void DoPost()
{
    string jsonparams = "{\"method\": \"actTakePicture\"," +
                        "\"params\": []," +
                        "\"id\": 1," +
                        "\"version\": \"1.0\"}";

    string url = "http://10.0.0.1:10000/sony/camera";

    var httpclient = new HttpClient();
    var jsoncontent = new StringContent(jsonparams, Encoding.UTF8, "application/json");
    httpclient.MaxResponseContentBufferSize = int.MaxValue;
    var response = await httpclient.PostAsync(url, jsoncontent);
    String text = await response.Content.ReadAsStringAsync();
}

It is a DVD deck to control. The remote controller is as shown below.

In order to control the device, you need to get the device id. It can be obtained by sending a request to Nature Remo mini using the code below. Please get the access token here.

static async void DoGet()
{
    string token = "Bearer " + "{access token}";
    string url = "https://api.nature.global/1/appliances";
    var httpclient = new HttpClient();
    
    httpclient.DefaultRequestHeaders.Add("Authorization", token);

    var response = await httpclient.GetAsync(url);
}

Since you can get the device id, use that the device id to control the power of a DVD deck.

The acquired id ( e1ac8815-1480-4914-bd77-a42c5037659b) is specified as follows, and the source is rewritten for POST request. A status code is returned in 200, it will succeed. I think It is able to write the code of the GET code and the POST code beautifully by using HttpRequestMessage and SendAsync.

static async void DoPost()
{
    string token = "Bearer " + "{access token}";
    string url = "https://api.nature.global/1/signals/e1ac8815-1480-4914-bd77-a42c5037659b/send";
    var httpclient = new HttpClient();
    var httpreqmsg = new HttpRequestMessage(HttpMethod.Post, url);

    httpreqmsg.Headers.Add("Authorization", token);

    var response = await httpclient.SendAsync(httpreqmsg);
}

Because I want to make the sample source code as simple as possible, I do not specify HEADER information and other necessary information neatly. For full-fledged use, please refer carefully to the Nature Remo API specification.

A programming of device is fun. I noticed after Nature Remo mini arrived at my house, but the second generation of Nature Remo has humidity, human feeling, and light sensor. I should have bought the second generation of Nature Remo!
