Hi,
recently I have bought the S6 vacuum cleaner from Xiaomi - great little toy 
I have built a status screen which worked perfectly showing me the battery status, etc. - however, for some odd reason the status is not being delivered anymore to Home Assistant. Looking at the log, I am receiving following:

Of which I am not sure how to interpret all of it 
My configuration content is pretty straight forward:
vacuum:
- platform: xiaomi_miio
host: 192.168.1.158
token: 624a61494d537a4f7a76433355375635
The token is correct - I have checked that two times.
I am continuously working on my HA environment, so it might as well be, that I have done some changes over the days, which changed the setup and impact the S6, but based on what I have in the log I read that the discovery takes too long. How could I increase either the time for discovery or improve the time taken for discovery?
I am using a RPI 3 B+which is dedicated to HA with some add-ons
Any idea, help is highly appreciated - thanks a lot!
Cheers
Sven
