Use CURL to read latest sensor data from EchoPortal:

curl -b ./cookies.txt -A "echoSensor" -F "json=true" -F "sn=yourDeviceNumber" -F "apikey=ff3f3275-f356-462a-7321-caf0b312fe02" -F "user=yourUsername" -F "pass=yourPassword" https://echosensor-server/api/
				

JSON output:

{
	"type":"LIGHT",
	"serial":"Z17795135172",
	"value":"964",
	"cpuTemperature":"16.67",
	"latestTime":"13:47:33",
	"latestDate":"2022/11/19"
}
				

you can set the parameter json=false to receive data in csv format:

964,53.33,14:10:59,2022/11/19,LIGHT

Error Code:

{
	"Code":"Session",
	"Type":"Auth.Error.x"
}

Use PHP and receive csv data

// create cookies file
$cookieFile = "./cookies.txt";
if(!file_exists($cookieFile)) {
    $fh = fopen($cookieFile, "w");
    fwrite($fh, "");
    fclose($fh);
}

// set json true or false
$pars=array(
'json' => 'false',
'sn' => 'DEVICE_NUMBER',
'apikey' => 'ff3f3275-f356-462a-7321-caf0b312fe02',
'user' => 'YourUsername',
'pass' => 'YourPassword',
);
//step1
$curlSES=curl_init();
//step2
curl_setopt($curlSES,CURLOPT_URL,"https://sgneep.com/portaldata_api/");
curl_setopt($curlSES,CURLOPT_USERAGENT,"echosensorHeader");
curl_setopt($curlSES,CURLOPT_RETURNTRANSFER,true);
curl_setopt($curlSES,CURLOPT_HEADER, false);
curl_setopt($curlSES, CURLOPT_POST, true);
curl_setopt($curlSES, CURLOPT_POSTFIELDS,$pars);
curl_setopt($curlSES, CURLOPT_COOKIESESSION, true); // Cookie
curl_setopt($curlSES, CURLOPT_COOKIEFILE, $cookieFile); // Cookie
curl_setopt($curlSES, CURLOPT_COOKIEJAR, $cookieFile); // Cookie
curl_setopt($curlSES, CURLOPT_CONNECTTIMEOUT,10);
curl_setopt($curlSES, CURLOPT_TIMEOUT,30);
//step3
$result=curl_exec($curlSES);
//step4
curl_close($curlSES);
//step5
echo $result;

Use with Python:

import requests
import http.cookiejar
#pip install requests

url = "https://echosensor-server/api/"
data = "sn=DEVICE_NUMBER&json=true&apikey=ff3f3275-f356-462a-7321-caf0b312fe02&user=YourUsername&pass=YourPassword"
headers = {'User-Agent': 'echosensor','Content-Type': 'application/x-www-form-urlencoded'}
cookies = http.cookiejar.MozillaCookieJar('cookies.txt')
cookies.load(ignore_expires=True)

r = requests.post(url, data=data, headers=headers, cookies=cookies)
print(r.text)
