Dutch Essent account with no readings?

[Giovenale2]

Hi team,
Really like your idea for this project! I have a NL Essent account, and I can see my usage online after logging in. Nevertheless, i get a parsing error in home assistant, because and '.find('Installations')' fails. When I try to use this code with spyder I get to the result xml, where the data pull seems to be successful, but it contains no readings.
I get 10 EANs, but each of them seems to have no readings. Below the response, with the EAN hidden. Any suggestion to solve this? I am really looking forwards to get my readings in HA :)

Oh, interesting. I just grabbed the first EAN when implementing this because that works for me. Does only one EAN return meter info or do multiple do? In the last case, how would I decide which is the correct EAN?

I get 10 EANs, but each of them seems to have no readings.

Oops, misread this. Could you check if the VerbruiksManager is enabled on the Mijn Essent website and if it has anything under "Meterstanden" for you?

[Giovenale2]

Wow, quick reaction!
Yes, i can access that part of the MijnEssent and I see monthly (some months 2 measures) incremental readings for :

Opnamedatum | Stroom dagtelwerk | Stroom nacht/weekend telwerk

Instead, I see missing values for

Stroom teruglevering, dagtelwerk | Stroom teruglevering, nacht/weekend telwerk

"Bron" is "Opgave door slimme meter" for every entry.

Hmm, that sounds about right then. You're sure not a single one of the EANs returns any readings? Because as far as I'm aware at least one of them should return this data.

[Giovenale2]

Yes, I am sure. I printed the content of each EAN directly from within your code. Any idea of what could be different from other cases?

[TheLastProject]

Can you try the code in the README again on the latest master branch?

from pyessent import PyEssent

essent = PyEssent(username=username, password=password)
for ean in essent.get_EANs():
    essent.read_meter(ean)

And see if it outputs anything at all?

[Giovenale2]

Interesting. The code does not beak now, but i also do not get any value out. If I print the server response from within your code as I did in the previous commit, I now get a simple

<Response [200]>

How odd, I expect output like this:

Just to make sure, under "Instellingen", both these boxes are checked?

[TheLastProject]

Should be fixed in #6.
