A simple example for how to export data from the Enelogic API (WSSE)

enelogic.py

# From: https://enelogic.docs.apiary.io/#introduction/option-1.-wsse-authentication

# Go to the developer center: enelogic.com/nl/developers.
# Add your app and choose a desired redirect url (only for OAuth2 purposes, if using WSSE just fill in a URL e.g. enelogic.com)
# Fill in values below

import hashlib
import json
import os
import requests
import random
import string
from datetime import datetime, timedelta

appid = "..."
appsecret = "..."
username = "...@..."
apikey = "..."

def wsse(username, password):
    nonce = ''.join(random.choice(string.letters + string.digits) for _ in range(16))
    created = datetime.utcnow().strftime("%Y-%m-%dT%H:%M:%SZ")

    hash = hashlib.sha1(nonce + created + password).digest().encode('base64').strip()
    
    return 'UsernameToken Username="%s", PasswordDigest="%s", Nonce="%s", Created="%s"' % (
        username, hash, nonce.encode('base64').strip(), created)

def enelogic_wsse(appid, username, appsecret, apikey):
    username = appid + "." + username
    password = appsecret + "." + apikey
    
    return wsse(username, password)

s = requests.Session()
s.headers.update({'Content-Type': 'application/json'})    

# Get buildings

# Note: you have to regenerate the WSSE every request...
s.headers.update({'X-WSSE': enelogic_wsse(appid, username, appsecret, apikey)})    

res = s.get("https://enelogic.com/api/buildings/")
res.raise_for_status()

buildings = {r['id']: r for r in res.json()}
#[
#  {
#    "id": 1505,

measurepoints = {r['id']: r for r in res.json()}

#    "mdId": 1,

for measurepoint in measurepoints:
    curr = datetime.strptime(measurepoints[measurepoint]['dayMin'][:10], "%Y-%m-%d")
    end = datetime.strptime(measurepoints[measurepoint]['dayMax'][:10], "%Y-%m-%d")
    
    while curr < end:
        fname = "enelogic/" + str(measurepoint) + "." + curr.strftime("%Y-%m-%d") + '.json'
        next = curr + timedelta(days=1)

        if os.path.exists(fname):
            curr = next
            continue
        
        print fname
        s.headers.update({'X-WSSE': enelogic_wsse(appid, username, appsecret, apikey)})    
        res = s.get("https://enelogic.com/api/measuringpoints/%s/datapoints/%s/%s" % (measurepoint, curr.strftime("%Y-%m-%d"), next.strftime("%Y-%m-%d")))
        res.raise_for_status()
        
        with open(fname, "w") as f:
            f.write(res.content)
        
        curr = next

Finally I managed to upgrade the WSSE example of Kleptog from a Python 2 to a Python 3 version (see code below for the essential parts of the authorization code).
There is only one remark:
The authorization works, but not always. Sometimes it gives an error:
403 Client Error: Forbidden for url: https://enelogic.com/api/
So far I did not solve this problem, but must something have to be related to:

• A problem with cookies?
• A caching problem?
• Or just the state of the Enelogic server (I tested this code with a limited account (maximum 500 calls)?
• or a combination of above, because the problem sometimes disappears after the initial error message

def autorisatie():
    username=u"AppId.EnelogicUsername"
    password="AppSecret.UserAPIKey"
    password=password.encode('utf8')
    nonce = ''.join(random.choice(string.ascii_letters + string.digits) for _ in range(16))
    nonce=nonce.encode('utf-8')
    created = datetime.utcnow().strftime("%Y-%m-%dT%H:%M:%SZ")
    created=created.encode('utf-8')
    hash = base64.b64encode(hashlib.sha1(nonce+created+password).digest()).strip()
    wsse= 'UsernameToken Username="%s", PasswordDigest="%s", Nonce="%s", Created="%s"' % (username, str(hash, 'utf8'), str(base64.b64encode(nonce).strip(),'utf8'), str(created,'utf8'))
    return(wsse)

wsse=autorisatie ()
s.headers.update({'X-WSSE': wsse}) 

Dear Kleptog,

Thank you for your script. I try to import the Python script into Power BI and thus create a table with all data.

I almost succeeded. I only work with the oAuth2 api, so I deleted the WSSE rules.

However, at the end of the script, Python returns a syntax error. I have the impression that it ends up in a certain loop where it does not come out or that the rule: next = curr + timedelta (days = 1) is not clear.

The end of my script is now:

for measurepoint in measurepoints:
    curr = datetime.strptime(measurepoints[measurepoint]['dayMin'][:10], "%Y-%m-%d")
    end = datetime.strptime(measurepoints[measurepoint]['dayMax'][:10], "%Y-%m-%d")
    
    while curr < end:
        import os
        dirname = os.path.dirname(__file__)
        fname = os.path.join(dirname, "enelogic/" + str(measurepoint) + "." + curr.strftime("%Y-%m-%d") + '.json'
        next = curr + timedelta(days=1)
        
	if os.path.exists(fname):
            curr = next
            continue
        
	print (fname)
        res = s.get("https://enelogic.com/api/measuringpoints/%s/datapoints/%s/%s" % (measurepoint, curr.strftime("%Y-%m-%d"), next.strftime("%Y-%m-%d""?access_token="***")))
        res.raise_for_status()
        
	with open(fname, "w") as f:
            f.write(res.content)
        
        curr = next

At the start of the script I imported timedelta from datetime.

Do you have an idea how I can solve this?

Hi gjmeer,

You have an oauth2 script working? Would you like to share the code (i can't get it working)?

Dear J,

It is long time ago i tried this Pythonscript in Power BI. The OAuth2 did work, but I didn't recieve the data I want.
I followed the instruction on enelogic.docs.apiary.io to create an appid, appscret and apikey.

Do you have a working script beside the OAuth?

The Pythonscript is as follows:

dear gjmeer

Thanks for the reply. I already had the wsse script working, but it seems a little unstable (authentication errors now and then). That is why i was searching for an oauth2 solution. Mine works fine with the inintal access token generated via the 'documented' google playground method, but i can't get token refreshed from a python script.

Thanks for your reply, i will struggle on :-)

Dear Jeroen,
As ypu have a working version of a WSSE script could you help me. The OAUTH2 is too complex for me. I would like to just execute the python script on my windows laptop. But I get some errors. I generated the keys with https://enelogic.com/nl/developers/
appid = "10105_327wdyv10aiow4occc8c0ds08wskodc4scsckoo8dkks4cckkk8"
appsecret = "1rjn5swy4ux3406sw0kk048kc4wwcolwcgskwkws0so0wo084g"
username = "[email protected]"
apikey = "4mqjcj35oq04occcskkssc4oc00cog0"
And used the apikey from the enelogic account.
Is this the correct way to obtain the parameters.
The script is not working not on windows and not on raspberry linux.
Could you share your script and information, I know it is a little unstable.
Thanks for your help.

for me this works:
I have one file pulling in all sorts of energy related data (energie_data.py) which uses my enelogic.py

energie_data.py:

import requests
import enelogic

...
...
# enelogic (ruwe) data opvragen buiten de functie, anders failt de wsse authenticatie steeds...

Based on the Enelogic API docs and some insights I got from the above, I have a running Python3 script that gets my metering data (based on the Enelogic measuringpoint_id) between 2 dates and saves the interval volumes (calculated between two consecutive readings from Enelogic) in a certain format in CSV.
The script does some basic checks but nothing special.
I use OAuth2.0, but it requires me to get a new accesstoken every 2 or 3 days. This is annoying so I'd like to learn how to refresh the accesstoken using the refreshtoken that is supplied via the Google OAuth 2.0 playground..... Any help appreciated.
