VR921 internet module, with VR33 OpenTherm controller

Problem description

Hello, I have a VR921 internet module which is returned over the API in /homes call, but then since control id is missing, no other data is fetched (see logs below). Also there is an an error which asks to report itself as an issue, not sure if its just about the control id or something else. I am controlling the heater over VR33 OpenTherm interface, and the mobile app also does not show any control information.

1. Howevere the mobile app does show electric energy and gas consumption over time, is there no way to access these statistics in absence of controller?
2. Or would be even more fun if VR33 controller was accessible somehow over another API, surely it has quote some data and sensors too. Let me know if I can poke around with some other API calls / debug something else.

the mobile app also does not show any control information

So there's nothing in the MyVAILLANT app? Or is it working? If it works, you would probably need to reverse engineer the API to find out what values are being sent.

[girtsn]

The MyVAILLANT app is not gshowing any controls, but it does show statistics of gas and electricity usage.

[signalkraft]

I wasn't aware that this case exists. Could you try reverse engineering to find out what API calls are being made and what they return in your case?

Generating test data may also help.

[girtsn]

Hello again. Took me some time to try (btw those instructions to reverse engineer api calls are a bit outdated, apk won't work for latest versions and xapk did give an error in the generated binary manifest, had to edit it passing --wait argument to remove that faulty line) - but I extracted the relevant requests and responses, the way to get the heating/water heating usage data is to go after the emf-system API and then call consumption endpoints using the emf uuid. requests-responses.zip it would be great to see consumption data displayed in Home Assistant...

@signalkraft did the data from @girtsn help?
