Some devices cannot connect to the app

Could be caused by using different encryption key in new firmwares.

Starting from the AC firmware v1.21, module uses another way of the encrypting to interact in local network

Additional references:

• gree.py - "The length of the provided data is not a multiple of the block length" exception on initial search tomikaa87/gree-remote#52
• add new encryption method RobHofmann/HomeAssistant-GreeClimateComponent#165

Hey, I have exactly the same issue. Today I've installed 2 Gree Amber Prestige ACs, both connected to my 2.4G network. They are searchable via Gree app, but in Homey I see only info about "Your HVAC went Offline". Of course, I have the latest firmware - so it sounds like this problem with encryption.

Confirmed for me as well with 1.21 firmware.

Is there anything I could do to assist,
