Since my marked id works without any issues, would you mind sharing your market ID with me? Right now I am unable to reproduce the isse

[jones1894]

Hi, I noticed it is working again. I really can't say why. I tried to reboot Home Assistant an nothing worked, and then all of a sudden it was back on... Maybe it was a temporary issue on the Rewe API Side.

[FaserF]

Yeah most likely it was a temporary issue with the rewe API itself

I actually have the same error. I'm on HA 2024.1.0 and wanted to setup your integration. Is it working for somebody else and this HA version?

Edit: Should be related to this issue https://github.com/foo-git/rewe-discounts/issues/14. Edit2: Got it solved. It was the ecdh curve. Will open a PR.

[FaserF]

Thanks, fixed with your PR and release 2024.01.0

In case this issue should pop up again, check out foo-git/rewe-discounts#14 as I added just now a second code path in a testing branch using a different Rewe API which might solve it.
