Gree (tosot) app 1.24.1.13 +fw v1.43 +remote wired XE7A-24 controller

Hi,

The integration does not find any airco.
I by adding the gree integration to HACS such that I get at least the question of automatic or manual discovery.
I have the encryption key extracted from the gree cloudserver and the UID.
But still:

Also I installed PCAPDroid on my phone and the strange thing is that also there NO device responds to the {"t":"scan"} broadcast.

What I do see is that all traffic (encrypted) seems to go to
mqtt-eu.gree.com at port 1984?

Any idea how I can get communication to my arco (FTS-18R2) going?

I will gladly assist with debugging if I am instructed what to do next.

I also have XE7A-24 controller with the same exact behavior. I can find the device on UDP 7000, connection succeeds when I test netcat/nmap. But still get the same Error getting device encryption key! described above.
