Same issue.

Update: I went for the following solution: https://github.com/Hypfer/esp8266-midea-dehumidifier

The client request :
https://mapp.appsmb.com/v1/appliance/transparent/send/new

seems to fail and return a non-json, but rather HTML response of "502 Bad Gateway"

not being a json response seems to cause the code at line 596 of midea_client.py :

data = response.json()

to fail.

The Midea IOS app seems to get this 502 Bad Gateway reply to this request, ignores it and move forward with no apparent negative consequences. Watching this interaction via mitmproxy.org proxy.
