Cannot add one of three devices. Error getting device encryption key!

[kielczu]

I have the same problem with XE7A-24/HC. I have added two devices succesfully, but the third one is always unavailable.

Gree A/C version 2.14.2.
Wifi version v1.38.

These are my settings:

platform: gree
name: GREE-S1
host: 192.168.8.221
port: 7000
mac: '50:2C:C6:DF:73:21'
target_temp_step: 1
platform: gree
name: GREE-S3
host: 192.168.8.223
port: 7000
mac: 'C0:39:37:0F:E9:A3'
target_temp_step: 1
encryption_version: 2
platform: gree
name: GREE-S2
host: 192.168.8.222
port: 7000
mac: '94:24:B8:01:7A:44'
target_temp_step: 1
And the log for GREE-S3 is always:

I have spoken to gree suppor and i found out that there are different versions of the same XE7A-24/HC wifi module. The one which does not work (failed to get encryption key) apparently is a newer one that only uses bluetooth and does not have the legacy hotspot feature.

So it seems when we add the new module using bleetooth the encryption key is different.

Can anybody help with that? Perhaps the default encryption keys must be updated in the code?
