Support for Air Purifier 3/3H (zhimi.airpurifier.mb3)

[petrkotek]

Today, I got the newest Xiaomi's Air Purifier delivered - it's Xiaomi Air Purifier 3/3H (and identifies itself as zhimi.airpurifier.mb3).

Soon after, I found out it's not supported by miio yet (and therefore neither by Home Assistant which I use).

I'm a developer myself and happy to contribute & implement the support for it. I'll try to work on this in my spare time (kicking off by reading instructions here https://github.com/aholstenson/miio/blob/master/docs/missing-devices.md).

If somebody else has this device, I'd be happy to collaborate on the implementation.

• Mi Air Purifier 3 - not working YinHangCode/homebridge-mi-airpurifier#36

I'm now to turn ON/OFF the device:

miio protocol call 192.168.0.22 set_properties '[{"did":"MYDID","piid":2,"siid":2,"value":true}]' #ON
miio protocol call 192.168.0.22 set_properties '[{"did":"MYDID","piid":2,"siid":2,"value":false}]' #OFF

Change fan speed, e.g.:

miio protocol call 192.168.0.22 set_properties '[{"did":"MYDID","siid":2,"piid":4,"value":1}]' # level 1
miio protocol call 192.168.0.22 set_properties '[{"did":"MYDID","siid":2,"piid":4,"value":2}]' # level 2
miio protocol call 192.168.0.22 set_properties '[{"did":"MYDID","siid":2,"piid":4,"value":3}]' # level 3

I just realised that Home Assistant actually uses https://github.com/rytilahti/python-miio

As I don't really need the support in this library, I'm closing this thread.

Petrkotek: this library is used by homebridge so if you ever need to get proper homekit integration of your 3h (as air purifier not just fan), you'll need this library then.
