Hi all, I needed accurate price data from ENGIE so I spent some time reverse-engineering their platform. I’m planning to publish my integration on HACS soon but I would like to have it tested by other people first.
A few things to note:
-
Currently, only 2FA via SMS and e-mail are supported. Passkeys and itsme support are off the table, not interested in touching those. I’m also not sure what will happen when ENGIE forces 2FA on all of their customers in March.
-
I was only able to test with Easy Variabel. The API call for prices uses MONTHLY for maxGranularity, so this might not be ideal for people with a dynamic contract.
-
ENGIE seems to be very strict with their access tokens: they get revoked after about 2 minutes, so the integration refreshes the token every minute in the background. There is a binary sensor to keep track of the authentication status.
-
The integration creates sensors for offtake and injection prices (both including and excluding VAT), per EAN. Injection sensors are only created when the data is available (e.g. gas will only have offtake).
For those interested in the login flow, I’ve included a Bruno collection in the repository.
Feel free to test this out by spinning up the devcontainer or by manually adding the ingration, all contributions and improvements are welcome
