Trouble Connecting HVAC to WiFi: Gree+ App and Alternative Command Not Working

[Freeman]

Hello and thank you for offering an alternative method to connect my HVAC. Unfortunately, the Gree+ app never worked with my AC, and I suspect my model might be one of the first with the WiFi button on the controller.

I noticed in another comment that the command was tested with Mac. I have Ubuntu, Windows, and Mac computers at home, so troubleshooting is not an issue.

I used the command, on Mac, almost as is but changed the IP since my router is 10.0.10.1. Could this be the problem?

echo -n "{\"psw\": \"YOUR_WIFI_PASSWORD\",\"ssid\": \"YOUR_WIFI_SSID\",\"t\": \"wlan\"}" | nc -cu 10.0.10.1 7000

Before entering the command, I turn off the WiFi on the Gree remote and hold the WiFi button until I hear the beep.

Upon entering the command, there's no output, errors, or hanging; it seems to be working.

Unfortunately, I can't find the Gree on my network. Maybe it's there, and I can't see it.

Is there a way to find the MAC address of my AC while I'm connected to the gree-C620A49C network (the heat pump integrated WiFi)? This would make it easier for me to search and confirm its connection to my network.

I'm willing to tip anyone who can help me connect my HVAC. This is crucial as I have a contract with my electrical company to save money and receive free thermostats. I want to automate the heat pump with Home Assistant and MQTT.

Thank you very much for your help!
