Cannot connect to Gree GWH18AAD-K6DNA1D

[damonmaria]

Describe the bug Trying to use this with a Gree GWH18AAD-K6DNA1D, and having no luck. I can successfully control the AC using the GREE+ Android app but installing this component I always get: "No devices found on the network".

I know the AC's IP address but using both nc and nmap I can't find any open ports on it. I am presuming it's TCP. I gather from the README port 7000 should be open.

I am a developer by trade and have network skills (but am a HA newbie) so I'm happy to try anything you suggest.

The following was in the log but I don't know if this relates to this component trying to find the AC unit:

I also attempted to add the configuration manually as per the README but I get the following:

The gree platform for the climate integration does not support platform setup. Please remove it from your config.
