Closed JKorf closed 4 years ago

JKorf commented 4 years ago

Discover fails. Device can be found, but response can't be parsed? Used the latest .19 version.

new version msmart==0.1.20 fixed this bug

JKorf commented 4 years ago

Thanks for the quick response. It indeed fixed the padding issue, however it times out when trying to connect to the device. Any advice?

mac-zhou commented 4 years ago

sorry. it means unsupported.

reneklootwijk commented 4 years ago

I have the same with 4 ac's. Do you have a clue what is the issue to support these ac's? I can control them via the midea air and nethome plus apps.

JKorf commented 4 years ago

I'm from the Netherlands as well, so we could very well have the same ac type. I'm still looking for a solution, searching around in the msmart sdk. It's obfuscated though, so pretty hard to find anything..
