Max integration broken?

1

Hi,

since upgrading to lastest version the max integration is not working anymore.
Seems like a python problem. Output from homeassistant.log:

Traceback (most recent call last):

Seems like you’re affected by this issue: https://github.com/home-assistant/core/issues/28811
You can try to use the changes of @onkelbeh as a custom integration :slight_smile:

I dont think so. It has been working for over a year now and got broken since the last update.
I downgraded but now the problem persists.
My error differs a lot from the error reported on the link “IndexError: bytearray index out of range”
Does anyone have further tips?

Hi,

this is definitely not caused by #28811.
This looks like a connection issue, did you try to reset the cube?

Sometimes these hang themself if you open more than one connection simultaneously.

Hi onkelbeh,

you were right, It was a conneciton issue. The cube was crashed, I did a complete reset of the cube (as every few months, since there is no permanent connection configurable) and it worked again.

Topic can be closed, thanks!
