Hey there @rytilahti, @syssi, mind taking a look at this issue as its been labeled with an integration (xiaomi_miio) you are listed as a codeowner for? Thanks!

i'm getting the same thing since upgrading to 0.112 from both the xiaomi_miio.fan and xiaomi_miio.vacuum platforms.

2020-07-02 08:15:11 ERROR (MainThread) [homeassistant.helpers.entity] Update for vacuum.roborock_0 fails

During handling of the above exception, another exception occurred:

the vacuum is, however, reachable:

wbradmoore@habox:~$ docker exec -it homeassistant bash
bash-5.0# mirobo --ip 192.168.x.x --token xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

This happens when the device does not respond to the handshake request and has been fixed already in upstream (rytilahti/python-miio#731 ), so this will be fixed when new python-miio gets released and the dependency gets bumped (likely for 0.113).

This happens when the device does not respond to the handshake request

it happens (the above failure) 100% of the time, for all my fans and vacuums - is that expected based on your understanding of the bug?

also curious if i can jump into the container and manually update python-miio...

I tried to update /usr/local/lib/python3.7/site-packages/miio/miioprotocol.py using https://raw.githubusercontent.com/rytilahti/python-miio/master/miio/miioprotocol.py on the hassio container but my vacuum is still unavailable after restart. It responds to mirobo command command though.
EDIT: I just used the 0.111.4 xiaomi_miio as custom_components for now and it's working

i tried replacing the entire /usr/local/lib/python3.7/site-packages/miio/ dir with the current version, and got the same constant vacuum failures (it looks like a fan was working, though?)

using the HA 0.111.4 custom_component works though, good idea.
