Diagnostics information

(based on my comment: home-assistant/core#122076 (comment))
I have two devices, and one that got an upgrade from firmware v1.17(?) to v1.23 is no longer "cooperating" with integration. I see something changed. Debug below.

• some fields added
• some fields empty

All was working with Gree firmware 1.17
Failed with Gree firmware 1.123

One of the comments in the linked Issues claims that encryption version 2 fixes the problem.

One of the comments in the linked Issues claims that encryption version 2 fixes the problem.

This refers to a custom integration available through HACS, where they wrote their own API connector implementation. Gree changed up the API after v1.21, the integration refers to this change as encryption 2

Support for the new encryption type is being worked on:
#92

Finishing up testing, thanks for the patience everyone.

Changes are merged, should be in 2024.9 HA release.

I think it made it into HA version 2024.8:
