Hello ophilips

my code is pretty basic but does the trick of showing the vacuum in the Homekit and having the on/off button:
#Xiaomi Mi Robot Vacuum
vacuum:

• platform: xiaomi_miio
  host: ##########
  token: ###########
  name: To
  However would it be possible to have this information showing in the Home App in the iPhone? (the print is from the EVE app but the principle is the same)
  

Hey @WLines84, by using your code (which is just the home assistant standard config) you only have access to the on/off switch in Apple Home. It is a new feature since version 0.110 https://www.home-assistant.io/blog/2020/05/20/release-110/#homekit
If you want to have more features like vacuum speed, zones etc. it is still necessary to add some more code to your config.

Hi @ophilips

Long time ago (-:
I wonder if you have updated the code since the fan.speed service seems not to be working anymore. It would be nice to share a new code if you can.
Thanks

Doesnt work anymore.

Deprecated services: fan.set_speed

Does anyone have a working config for Homekit with latest HA versions?
