Port and domain configuration

[IlogicalKarma]

For those who have come across this repo hoping to prevent external connections from their AC, here is some information I came across:

The port is NOT always 5000, in my case, it was 1813. To find it I suggest setting up a network with an access point that has ssh access and a tool such as tcpdump (I also recommand using Wireshark to remotely monitor the packets with filtering and information displayed neatly). While monitoring the packets, you should unplug the unit and plug it in again after 10-20 seconds. It will attempt to resolve the domain assigned to it and, following that, it will send a packet to one of the resolved addresses.

The linked repository for ConfigTool did not work for me, but you should be able to see the DNS request with the name when tracking down the port. In my case it was eu.dis.gree.com.

Please note that my AC unit is using version 1.25, but it should function similarly to 1.21. Also note that, despite the fact that it works, I am experiencing delays and timeouts in home assistant when attempting to connect to it. This is likely something that cannot be fixed without a replica of the server.
