Xiaomi Raw

This is a custom component for home assistant to facilitate the reverse engineering of Xiaomi MiIO devices.

Please follow the instructions on Retrieving the Access Token to get the API token to use in the configuration.yaml file.

Credits: Thanks to Rytilahti for all the work.

Features

Power (on, off)
Sensor value (RSSI in dBm of the WiFi connection)
Raw command (method + params)
Set properties (property list)
Attributes (can be extended by "Set properties")
- model
- firmware_version
- hardware_version
- properties

Install

You can install this custom component by adding this repository (https://github.com/syssi/xiaomi_raw) to HACS in the settings menu of HACS first. You will find the custom component in the integration menu afterwards, look for 'Xiaomi MiIO Raw'. Alternatively, you can install it manually by copying the custom_component folder to your Home Assistant configuration folder.

An example for using the raw sensor to create a rice-cooker temperature sensor based on the raw data. Tested on an chunmi.cooker.normal2. This sensor always provides the current temperature unlike the the official sensor that only works during the rice program.

sensor:
  - platform: xiaomi_miio_raw
    name: cooker
    host: 192.168.0.122
    token:
    sensor_property: 'unnamed11'
    default_properties_getter: 'get_prop'
    default_properties:
    - 'all'
template:
  - sensor:
      - name: "Cooker Temperature"
        unit_of_measurement: "°C"
        state: "{{ states.sensor.cooker_2.state[28:-2] |int(base=16) }}"
        state_class: measurement
        device_class: temperature
        availability: "{{ states.sensor.cooker_2.state != 'unavailable' }}"
