Mi Flora

• Get MAC Address for the Mi flora

  $ bluetoothctl scan on | grep -i flo
  [NEW] Device XX:XX:XX:XX:XX:XX Flower care
  

• Create a new ESP Home integration to track the sensor:

  I name my sensors with numbers so I can write the number on them and identify them easily. You only need to assign sensors to rooms to have them easily available when looking for them on dashboards.

  # Sensors
  esp32_ble_tracker: # Required for BLE scanning
  
  sensor:
  - platform: xiaomi_hhccjcy01
      mac_address: 'XX:XX:XX:XX:XX:XX'
      temperature:
      name: "Flora 1 Temperature"
      moisture:
      name: "Flora 1 Moisture"
      illuminance:
      name: "Flora 1 Illuminance"
      conductivity:
      name: "Flora 1 Soil Conductivity"
      battery_level:
      name: "Flora 1 Battery Level"
  

• Validate and upload the configuration to your ESP device.

• With that, you could already create a card with the sensors provided by the integration, but for better visual information a plant object can be created with aproppriate values. Information comes from the Mi Flora App, but someone dumped the database and it's available also on github.

  From the spreadsheet:

  • Moisture: min_soil_moist/max_soil_moist
  • Temperature: min_temp/max_temp
  • Conductivity: min_soil_ec/max_soil_ec
  • Brightness: min_light_lux/max_light_lux

• Create a plant monitor on the configuration.yaml file:

  plant:
    parsley:
      sensors:
        moisture: sensor.flora_1_moisture
        battery: sensor.flora_1_battery
        temperature: sensor.flora_1_temperature
        conductivity: sensor.flora_1_soil_conductivity
        brightness: sensor.flora_1_illuminance
      min_moisture: 28
      max_moisture: 75
      min_battery: 20
      min_conductivity: 100
      max_conductivity: 2000
      min_temperature: 5
      max_temperature: 35
      min_brightness: 2500
      max_brightness: 55000
      check_days: 3
  

• Restart Home Assistant for the changes to take effect.

• Add a Plant Status Card to your dashboard and select the plant you just created.
