Hey there @rytilahti, @syssi, @bieniu, mind taking a look at this pull request as it has been labeled with an integration (xiaomi_miio) you are listed as a code owner for? Thanks!

Is this the fix for several of the recent issues? If yes, please fill the fixes section of the description, and let's schedule this then for the next point release.

@rytilahti no I don't think this is actually causing the real issues with not beeing able to set up the integration.
I think this is only causing errors in the log, but I am not sure.
We schould in any case merge this and see if it helps, but I think more is going on than just this.

@rytilahti can you approve/merge this?

[rytilahti]

I see no reason not to merge this, so let's get it done. Thanks 👍
