"Authentication failed" when connecting to wifi with Broadlink app (works on IHC)

See original GitHub issue

Hello,

I’m having trouble using broadlink-mqtt when I connect my broadlink to wifi via the “new” Broadlink App (https://play.google.com/store/apps/details?id=cn.com.broadlink.econtrol.international). After connecting to wifi with the app, when I start broadlink-mqtt i get the following error: (I masked the IP and MAC)

$ ./broadlink-mqtt/mqtt.py
[2020-06-30 10:19:29,407] DEBUG Connected to 'RM2' Broadlink device at '192.168.XXX.YYY' (MAC AA:BB:CC:DD:EE:FF) and started listening for commands at MQTT topic having prefix 'broadlink/RM2_DD_EE_FF/'
Traceback (most recent call last):
  File "/home/pi/broadlink-mqtt/mqtt.py", line 580, in <module>
    devices = get_device(cf)
  File "/home/pi/broadlink-mqtt/mqtt.py", line 363, in get_device
    device = configure_device(device, topic_prefix + mqtt_subprefix)
  File "/home/pi/broadlink-mqtt/mqtt.py", line 394, in configure_device
    device.auth()
  File "/home/pi/.local/lib/python3.7/site-packages/broadlink/__init__.py", line 225, in auth
    check_error(response[0x22:0x24])
  File "/home/pi/.local/lib/python3.7/site-packages/broadlink/exceptions.py", line 97, in check_error
    raise exception(error_code)
broadlink.exceptions.AuthenticationError: Authentication failed

(The error happens both on lookup or when I set the device_type, address and MAC on custom.conf).

But the weird thing is that when I connect the broadlink on wifi with the IHC App (https://play.google.com/store/apps/details?id=cn.com.broadlink.econtrol.plus) It works fine.

I made the test twice (connecting via broadlink app, getting the error, then resetting broadlink, connecting with IHC and working) and with 2 different broadlinks.

Right now it is working fine for me, so it’s ok if you guys close the issue. I don’t know if you are aware of this (or maybe it’s something wrong with my configurations). But i think it would help some people if this was stated on the README page until it gets fixed.

Thanks for your work on this project!
