[zawias]

I have the exact same error.

[plutec]

Try with this version of msmart:

pip3 uninstall msmart
pip3 install git+https://github.com/kueblc/midea-msmart.git@support-8370

[cjlawson02]

I have this problem too. Home Assistant 2021.7.2 on Docker. Happens with the correct pip package

[maraid]

Same error. I had a glance at it, but couldn't figure out the reason.

After self.request(request) in lan._authenticate() we get b'\x83p\x00\x05 \x0f\x00\x00ERROR'.
Maybe encoding should happen differently, but I'm not sure where to start. Let me know if I can help debugging this.

[eztmondom]

I had this problem, the received answer was b'\x83p\x00\x05 \x0f\x00\x00ERROR' (and authentication failed exception).
I installed this new msmart in my windows pc, but the problem is same.

The solution:
Restart the climate hardware device.

Other remark:
I noticed that I can control the climate via android app . But the dns server direct all request from module.appsmb.com:443 to my fake-cloud.service. I test the fake server with YAT, it went will (with dns redirect). That’s when I thought about restarting the climate. After reboot got the climate new server address from dns.
