Web connection seems not to work anymore
I have been using python-e3dc with the web connection to get some data out of e3dc reliable for ca 1.5 year. suddently, in the last few months, the webconnection functionalities is not working for me anymore, and my test script always fails:
Traceback (most recent call last): File "/home/ntesser/workspaces/private/python-e3dc/e3dc/_e3dc.py", line 225, in sendRequest self.rscp.connect() File "/home/ntesser/workspaces/private/python-e3dc/e3dc/_e3dc_rscp_web.py", line 427, in connect raise RequestTimeoutError e3dc._e3dc_rscp_web.RequestTimeoutError
I wonder if this is due to the new portal of e3dc and others are expiencing this problem or if it´s something off with my setup?
Which version of python-e3dc are you using?
Since 0.8.3 the websocket is consistently used. Before that change, for poll() parsing of the website was used.
I was using commit of Jan 24, 2022 of e3dc_rscp_web: https://github.com/fsantini/python-e3dc/commits/master/e3dc/_e3dc_rscp_web.py
so I guess it was a version 7.X.
However it does not seem that any major changes from WSS to website parsing happens in the meantime.
I tryed with the newest version and a bunch of versions between 7.x and current version, and always getting the same error. My impression is that at least for my credentials then endpoint "wss://s10.e3dc.com/ws/" is not working as expected.
Any tip on how to debug that endpoint?
The older versions did used to call https://s10.e3dc.com/s10/phpcmd/cmd.php for poll().

Please try again with the latest release and share the full exception.
Hi, sorry, I missed following up on this:
Here is the full stacktrace (I´ve updated python-e3dc to the last update of 4th of dec).

e3dc._e3dc.SendError: Max retries reached
I am using Ubuntu 22.04, python 3.9.12.
The test script I am using is the same as the example one in the readme.md and I double checked the value a few times and tried a few variations. e.g. serialnumber with or without 'S10-' in front. but always with the same issue. (connection timeout).
from e3dc import E3DC
USERNAME = 'yyy @gmail.com'
PASS = 'yyy'
SERIALNUMBER = 'yyy'
CONFIG = {"powermeters": [{"index": 6}]}
print("web connection")
e3dc_obj = E3DC(E3DC.CONNECT_WEB, username=USERNAME, password=PASS, serialNumber = SERIALNUMBER, isPasswordMd5=False, configuration = CONFIG)
# connect to the portal and poll the status. This might raise an exception in case of failed login. This operation is performed with Ajax
print(e3dc_obj.poll(keepAlive=True))
print(e3dc_obj.get_pvi_data(keepAlive=True))
e3dc_obj.disconnect()
I have the same issue. Python3.11 and latest commit. Connection via local works, ie user + password are correct.

Serial number +- "S10-" makes no difference.
It looks like E3DC changed their websocket endpoint configuration.
We are using wss://s10.e3dc.com/ws/ which is not working anymore but wss://s10.e3dc.com/ws is. I'll update the code.
