what a coincidence today I had some time to play around a bit. I got it to work locally. I extended the miio package for ZA1 support and put it next to the custom_component. And it works 😃 You can just test it from this branch: https://github.com/holygrolli/xiaomi_airpurifier/tree/local_smartmi

I have to find some time to check for the TVOC value, but everything else seems to work. And finally I need to cleanup and then create a merge request to miio and to this very repo here

Unfortunately, the airpurifier.za1 is still not working for me in HA without using the local fix of @holygrolli .

Is there still a chance for the pull request to the official repos, some time in the future, Andreas? Would be very much appreciated by a lot of people I think!
