Readme.md update

Hello! Today I have found your custom component and it works well with my Gree GWH18UC air conditioner, thank you!

I had a lot of trouble with wifi connection and I think it would be helpful if you would add this to readme file:

If you can't provide the encryption key (because you don't have any android device), you can use the component without it in the following way:

1. Reset your AC's wifi: Press "Mode" + "Wifi" buttons together for 5 sec
2. Connect your PC to AC's wifi, default password is: 12345678
3. Use the following command to connect your AC to your Wifi network: echo -n "{\"psw\": \"<YOUR_WIFI_PASSWORD>\",\"ssid\": \"<YOUR_WIFI_SSID>\",\"t\": \"wlan\"}" | nc -cu 192.168.1.1 7000
4. Now you can use the component without defining encryption key in config file

Also I think there is a way to obtain encryption key on iOS device, but this is UNTESTED:

You can download GREE.sqlite database file from your phone/tablet with iExplorer application (Windows/Mac) and you can see a deviceTable table in the database if you view the database file with DB Browser for SQLite application. This table has a publicKey column, maybe if you put this in the configuration file as encryption key, then it will work too. SQL command: `select publicKey from deviceTable;

Just test it on iPhone I find puplic_key but the uid is NULL

I followed these steps:

1. Download and install iTunes (if you don't have already)
2. Plug-in your phone
3. Create a local backup with iTunes. Make sure you have enough space on your C: drive
4. Download iExplorer. Demo/trial mode is fine, you don't need to pay for it https://macroplant.com/iexplorer
5. Open iExplorer and browse your backup (should find it automatically)
6. Navigate to: /Browse iTunes Backups/<MY IPHONE>/Backup Explorer/App/com.gree.greeplus/Documents
7. Export the GREE.sqlite file
8. Download SQLiteBrowser from https://sqlitebrowser.org/. Install it/download zipped version
9. Open SQLiteBrowser and open the exported database file
10. Browse 'deviceTable' table and copy the publicKey for each of your devices to the encryption_key parameter

In my logs I can see the following for my 4 units:

...The problem is that in Home Assistant I cannot see any device/entity... Any idea?

[Dilergore]

After removing the Encryption key I was able to see the devices and send commands to them but other than doing a beep for each command it was not working.

I reset all 4 units (actually what was working for me is MODE+WIFI on the remote for a few secs until a beep then unplugging the power for a few secs - I can also confirm that this was the only method what was working to reset them).

I used powercat on windows to set the wifi instead of the app: https://github.com/besimorhino/powercat/blob/master/powercat.ps1

1. Copy-Paste the script to the PS windows (there is a function in it)
2. Run a command to set your wifi settings:

powercat -c 192.168.1.1 -u -p 7000 -i "{`"psw`": `"WIFI_PASSWORD`",`"ssid`": `"WIFI_SSID`",`"t`": `"wlan`"}"

I can confirm that after this it is working. It might worth to include this more Windows friendly option in the readme.

Also it is not clear how it works. Is it sending requests directly to the WiFi modules or it is acting as a fake server? I was able to obtain the encryption key but when I call service from hassio or when I publish mqtt message nothing happens. It would be great to explain architecture in simple words and to add some troubleshooting instructions.

HI @Dilergore , what type of AC's dou you have? i have the same issue over here

HI @Dilergore , what type of AC's dou you have? i have the same issue over here

I have 4 indoor units connected to 1 outdoor unit. The indoor units are 1 Gree GWH09QB-K6DNB4I/I and 3 Gree GWH(07)QB-K6DND6A/I.

I can confirm that since my last comment here I've been using the units and no issues with them and their connection to the Wifi.
