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 encryption to interact in local network

Additional references:

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, let me know.

Hello there,

I just released a test version with the possible fix, please follow these steps

[dsaw703]

Hi, this fix works with the AC units using firmware V1.23, but does not work with wired controllers ("Main" as denoted in Gree App) using firmware V1.40.
