what can i be doing wrong?

Thanks

  1. kill midea app process on your phone
  2. modify lan.py add time.sleep(1) on line 54, like 
            self._socket.send(message)
        time.sleep(1)
        # Received data
        response = self._socket.recv(1024)
seppe912 commented 3 years ago

you need to import time too:

line 3:

import logging
import socket
import time
from msmart.security import security, MSGTYPE_HANDSHAKE_REQUEST, MSGTYPE_ENCRYPTED_REQUEST

and then modify line 54/55 like:

            self._socket.send(message)
            time.sleep(1)
            # Received data
            response = self._socket.recv(1024)

Are you going to put the fix into production?

mac-zhou commented 3 years ago

delete sleep and modify lan.py line 28, like:

            self._socket.settimeout(8)
            self._socket.setblocking(1)
            try:

then, try to test

I haven't found a best way to fix it in homeassistant, there is no this error

LaBoss commented 3 years ago

On HA mine often gives this error (In an hour 200x)

Sem Título

But entities appear as available. But I have to test even better

did you add self._socket.setblocking(1)?

LaBoss commented 3 years ago

I didn't put... Where do I put it in the custom component?

If put on MideaClimateACDevice init method Complains that the _socket property does not exist

lan.py

LaBoss commented 3 years ago

I don't know how to access the file... It must be inside the docker container and I can't access it (Its HASSOS)...

LaBoss commented 3 years ago

Ok I found a way to connect to the container, and it was slightly different

self._socket.settimeout(8)
            self._socket.setblocking(1)

With sleep(1) the timed out error also occurs
