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:
STATE Topic | Values to expect | Meaning |
---|---|---|

2020-03-29T15:44 | Timestamp of the last state update |
{mqtt_topic}/STATE/airQualityIndex |
0-999 | AQI current value from the frontpanel (PM2.5[µg/m³]) |
{mqtt_topic}/STATE/airQualityIndexAvg |
0-999 | Average AQI (Not yet seen elsewehere) |
{mqtt_topic}/STATEairTemperatureC |
NUM-1 | Current temperature in °C |
{mqtt_topic}/STATE/airRelHumidityPercent |
0-100 | Relative humidity in % |
{mqtt_topic}/STATE/fanMotorSpeed |
0.0-2500.0 | Current motorspeed in rpm |
