midea AC with protocol 8370

To communicate with your AC over LAN network without connection to internet you need:
https://github.com/kueblc/midea-msmart/tree/support-8370

In example.py fill:
device = ac('YOUR_AC_IP', YOUR_AC_ID)
device.authenticate('YOUR_AC_MAC', 'YOUR_SSID', 'YOUR_WIFI_PW')

Then you must run this code on something computer:

#!/usr/bin/python3
import socket
import os

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
sock.setsockopt(socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1)
sock.bind(('SOMETHING_SERVER_IP', 443))
sock.listen(5)
while True:  
    connection,address = sock.accept()  
    buf = connection.recv(1024)
    connection.send(buf)

This code make very stupid emulate of midea server, and is needed to your WiFi AC module dont restart if it cannot connect to module.appsmb.com:443 

Next you must set on your router DNS entry, for example on OpenWRT:
  Add to /etc/config/dhcp:
  config dnsmasq
    list addnhosts '/etc/hosts_my'
    
  In /etc/hosts_my:
  SOMETHING_SERVER_IP module.appsmb.com
  
  Then /etc/init.d/dnsmasq restart
  
  
With this method your AC dont reboot with renew DHCP lease, and can answer for authorization code. Unfurtunatellu, still restarting one time on 10m

I suggest using
#!/usr/bin/env python3
for shebang, as python isn't always installed in /usr/bin/
