Based on the very useful answers by @Rik to this question: AISWEI Solar API – Get Plant List, I am able to read my solar panels’ daily and monthly power production (somewhat confusing referred to as “bymonth” and “byyear”, respectively) from AISWEI’s cloud API. Total production (“bytotal”) also works nicely.
However, the “bydays” option, which is supposed to return the output at 20 minutes interval (I do not have the “pro” version), returns a timeout server error (504). I have tried both the Python and the PHP approach, and the issue applies to both. Has anyone experienced the same issue? Perhaps I have introduced a bug somewhere in the process, but I am unable to spot it.

My Python version is shown below. Basically, I have simplified @Rik’s code by removing the “pro” option and making getPlantOutput a function for all “period” parameter cases (bydays, bymonth, byyear, bytotal).

import requests
import json
import os
import hmac
import hashlib
import base64
from datetime import datetime

os.environ['TZ'] = 'Europe/Amsterdam'  # Setting the default timezone
crlf = "n"  # Line break

host = 'https://eu-api-genergal.aisweicloud.com'

ApiKey = '...'   
AppKey = '...'    
AppSecret = '...' 

today = datetime.today().strftime('%Y-%m-%d')
month = datetime.today().strftime('%Y-%m')

def getfromapi(url):
    global host, AppKey, AppSecret, ApiKey

    method = "GET"
    accept = "application/json"
    content_type = "application/json; charset=UTF-8"

    key = f"key={ApiKey}"
    url += ('&' if '?' in url else '?') + key
    s1 = url.split('?')
    s2 = sorted(s1[1].split('&'))
    url = s1[0] + '?' + '&'.join(s2)

    header = {
        "User-Agent": "app 1.0",
        "Content-Type": content_type,
        "Accept": accept,
        "X-Ca-Signature-Headers": "X-Ca-Key",
        "X-Ca-Key": AppKey
    }

    str_sign = f"{method}n{accept}nn{content_type}nnX-Ca-Key:{AppKey}n{url}"
    sign = base64.b64encode(hmac.new(AppSecret.encode('utf-8'), str_sign.encode('utf-8'), hashlib.sha256).digest())
    header['X-Ca-Signature'] = sign

    response = requests.get(f"{host}{url}", headers=header)
    
    data = response.text

    try:
        json_data = json.loads(data)
    except:
        json_data = {}

    json_data['status'] = response.status_code
    json_data['headers'] = response.headers

    return json_data

def getPlantOutput(period, date):
    url = "/getPlantOutput?period=" + period + "&date=" + date
    json1 = getfromapi(url)
    
    if json1['status'] == 200:
        return json1
    else:
        msg = f"Error retrieving data: {json1['status']}n{json1['headers']}"
        return msg

Now, calling getPlantOutput("bymonth", month), for instance, returns something like

{'key': '4b5102e528db40009b1a237f04a32663', 'dataunit': 'KWh', 'data': [{'time': '2024-05-01', 'no': '1', 'value': '59.8'}, {'time': '2024-05-02', 'no': '2', 'value': '59.0'}, {'time': '2024-05-03', 'no': '3', 'value': '57.8'}, {'time': '2024-05-04', 'no': '4', 'value': '47.1'}, {'time': '2024-05-05', 'no': '5', 'value': '28.1'}, {'time': '2024-05-06', 'no': '6', 'value': '16.5'}, {'time': '2024-05-07', 'no': '7', 'value': '62.2'}, {'time': '2024-05-08', 'no': '8', 'value': '52.6'}, {'time': '2024-05-09', 'no': '9', 'value': '47.6'}, {'time': '2024-05-10', 'no': '10', 'value': '12.1'}, {'time': '2024-05-11', 'no': '11', 'value': '28.9'}, {'time': '2024-05-12', 'no': '12', 'value': '62.8'}, {'time': '2024-05-13', 'no': '13', 'value': '62.3'}, {'time': '2024-05-14', 'no': '14', 'value': '61.4'}, {'time': '2024-05-15', 'no': '15', 'value': '60.6'}, {'time': '2024-05-16', 'no': '16', 'value': '61.3'}, {'time': '2024-05-17', 'no': '17', 'value': '62.6'}, {'time': '2024-05-18', 'no': '18', 'value': '60.0'}, {'time': '2024-05-19', 'no': '19', 'value': '50.1'}, {'time': '2024-05-20', 'no': '20', 'value': '43.8'}, {'time': '2024-05-21', 'no': '21', 'value': '57.4'}, {'time': '2024-05-22', 'no': '22', 'value': '56.5'}, {'time': '2024-05-23', 'no': '23', 'value': '26.0'}, {'time': '2024-05-24', 'no': '24', 'value': '55.2'}, {'time': '2024-05-25', 'no': '25', 'value': '47.7'}, {'time': '2024-05-26', 'no': '26', 'value': '38.9'}, {'time': '2024-05-27', 'no': '27', 'value': '35.5'}, {'time': '2024-05-28', 'no': '28', 'value': '0.0'}, {'time': '2024-05-29', 'no': '29', 'value': '0.0'}, {'time': '2024-05-30', 'no': '30', 'value': '0.0'}, {'time': '2024-05-31', 'no': '31', 'value': '0.0'}], 'status': 200, 'headers': {'Date': 'Tue, 28 May 2024 19:57:28 GMT', 'Content-Type': 'text/plain;charset=UTF-8', 'Content-Length': '1512', 'Connection': 'keep-alive', 'Keep-Alive': 'timeout=25', 'Server': 'Kaede/3.5.3.777 (ec3d9i5ys)', 'X-Ca-Request-Id': '791B21C1-BD4C-4E4B-916F-A78FEE5A5684'}}

that is, each day’s total production this month. However, calling getPlantOutput("bydays", today) or, say, getPlantOutput("bydays", "2024-05-10") returns

Error retrieving data: 504
{'Date': 'Tue, 28 May 2024 20:00:55 GMT', 'Content-Type': 'application/oct-stream', 'Content-Length': '0', 'Connection': 'keep-alive', 'Keep-Alive': 'timeout=25', 'X-Ca-Error-Message': 'Backend service request timeout', 'Server': 'Kaede/3.5.3.777 (ec3d9z7df)', 'X-Ca-Error-Code': 'D504TO', 'X-Ca-Request-Id': '56DF2B30-8A1B-4F18-98A3-10EC0ED7741C'}

I also tried using the host https://api.general.aisweicloud.com instead of https://eu-api-genergal.aisweicloud.com, but I don’t know if my data would be available there at all, and also I don’t seem to be able to connect to it:

HTTPSConnectionPool(host='api.general.aisweicloud.com', port=443): Max retries exceeded with url: /getPlantOutput?date=2024-05-28&key=4b5102e528db40009b1a237f04a32663&period=bydays (Caused by SSLError(CertificateError("hostname 'api.general.aisweicloud.com' doesn't match either of '*.aisweicloud.com', 'aisweicloud.com'")))

Any thoughts?
