HVAC WiFI Config

[hirani89]

Hi, Thanks for developing and sharing the code. I tried to run the wifi command on my macbook while connected to the AC in AP mode.

There was one problem initially when trying to run the nc command. I then realised that when copying the command from GitHub, the quotes are not in the right encoding. Notice the two different kinds of quotes in \”ssid\".

After I fixed that, something interesting happed.

This is what it returns:
{"t":"ret","r":200}

It then stays there with the cursor flashing.
Can you please write in the readme what the output for that command should be.

Regards,

I also have the same return string.

Did you find solution?

Ok, this string:
{"t":"ret","r":200}
means that command was successful and AC will soon connect to Wifi using given credentials.

So just needed to wait a little more. (up to a few minutes)

I am trying to connect to my AC in AP mode but I do not know the password. Is there default one?
I have a Vesser air conditioning with a Gree module. I have used EWPE app before.

I found it! May be useful to someone - WIFI pass: "12345678".

Just purchased and installed Cooper&Hunter CH-S09FTXAL-SC heat pump and try to setup wifi.
Android app Ewpe Smart found it but was unable to connect heat pump to home wifi.

Then I tried with netcat from Linux and it fails also...

Port 7000 is open

`
[timo@fedora ~]$ sudo nmap 192.168.1.1 -sU -p 7000
Starting Nmap 7.93 ( https://nmap.org ) at 2023-01-17 19:40 EET

But when I try to setup wifi, I get following error

[timo@fedora ~]$ echo -n "{\"psw\": \"wifi pass\",\"ssid\": \"wifi ssid\",\"t\": \"wlan\"}" | nc -cu 192.168.1.1 7000 Ncat: TIMEOUT. [timo@fedora ~]$

Any ideas what could be the problem?

For everyone who reached this page from Google and is looking for a command to bind a device to your WiFi - this is the command that worked for me:
echo -n '{"psw": "MyPassword", "ssid": "MySSID", "t": "wlan"}' | nc -u -w1 192.168.1.1 7000
