Hello,
Tonight, I will look at creating an integration to read Gaz consumption data from the distributor’s website.
I think I will start from what has been done here: GitHub - ssenart/home-assistant-gazpar: GrDF Gazpar meter integration for Home Assistant · GitHub
There is another solution that no longer seems to work: GitHub - vingerha/gazpar_2_mqtt: Revamp of the abandoned gazpar2mqtt · GitHub
I’m all ears for any other suggestions.
My recommendation, the simplest thing is to create an empty repo and then type this into Claude:
In this repo, I want you to create an external integration « GRDF Gazpar » for reading gas consumption data.
Start from the official integration template: GitHub - GladysAssistant/integration-template-js: Gladys Assistant Integration template for a JS external integration · GitHub
Then let him surprise you 
I don’t think it’s a good idea to suggest a technical solution to him, generally he’s better than us at it and imposing a solution « restricts » his reasoning 
Have fun!
