My Viessmann AC that I control using Gree+ won't get detected inside HA.

The problem

It won't recognize my AC. I use https://play.google.com/store/apps/details?id=com.gree.greeplus&gl=US this app to manage it, also I have it inside Google Home. The HA integration just says:

Hi there, hi @cmroche I have the same issue over here. Saunier duval ac's (spinoff gree). Visible in the gree+ app, but get the same error.

Log error: Error doing job: Exception in callback _SelectorDatagramTransport._read_ready() Traceback (most recent call last): File "/usr/local/lib/python3.10/asyncio/events.py", line 80, in _run self._context.run(self._callback, *self._args) File "/usr/local/lib/python3.10/asyncio/selector_events.py", line 1035, in _read_ready self._protocol.datagram_received(data, addr) File "/usr/local/lib/python3.10/site-packages/greeclimate/network.py", line 107, in datagram_received obj["pack"] = DeviceProtocol2.decrypt_payload(obj["pack"], key) File "/usr/local/lib/python3.10/site-packages/greeclimate/network.py", line 131, in decrypt_payload decrypted = cipher.decrypt(decoded).decode() File "/usr/local/lib/python3.10/site-packages/Crypto/Cipher/_mode_ecb.py", line 196, in decrypt raise ValueError("Data must be aligned to block boundary in ECB mode") ValueError: Data must be aligned to block boundary in ECB mode

Looks like encryption keys/mode has changed. Consider these models/firmware unsupported until someone can identify the keys and add it to open source.

I'm a bit too curious, how does that process normally go? Like I have the AC, I have the app(s) that work with it, I have a computer with putty on in and friends who are capable of disassembling the unit, shall that need occur.

@kubo6472 The original encryption key was extracted from the Android APK directly, there's a new key being used but from what I can tell through GitHUB no one has been able to identify what that key is yet. The greeremote project is likely a good source to follow this effort, there was an issue created there some time ago now about it.

@cmroche anything changed since your last comment on this? I also would like to use my Viessmann AC with this integration.
