# POC: Xiaomi Airpurifier 3H MQTT Bridge
|
|
|
|
|
This is a proof-of-concept, lacking a lot of errorhandling.
|
|
|
|
|
|
|
|
|
|
The Xiaomi Airpurifier 3H uses the (new) miot api.
|
|
|
|
|
This script bridges the air pufifier to the following state and control topics in mqtt.
|
|
|
|
|
|
|
|
|
|
These topics are reported from the device:
