Mi Flora Plant Sensor

The Mi Flora plant sensor is a small Bluetooth Low Energy device that monitors not only the moisture, but also light, temperature and conductivity. As only a single BLE device can be polled at the same time, the library implements locking to make sure this is the case.

To use your Mi Flora plant sensor in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
  platform: miflora
  mac: xx:xx:xx:xx:xx:xx
  name: Flower 1
  force_update: false
  median: 3
   - moisture
   - light
   - temperature
   - conductivity
  • mac (Required): The MAC address of your sensor. You can find this be running hcitool lescan from command line.
  • name (Optional): The name displayed in the frontend.
  • force_update (Optional): Sends update events even if the value hasn’t changed.
  • median (Optional): Sometimes the sensor measurements show spikes. Using this parameter, the poller will report the median of the last 3 (you can also use larger values) measurements. This filters out single spikes. Median: 5 will also filter double spikes. If you never have problems with spikes, median=1 will work fine.
  • monitored_conditions (Required): The paramaters that should be monitored.
  • timeout (Optional): Define the timeout value in seconds when polling (defaults to 10 if not defined)
  • retries (Optional): Define the number of retries when polling (defaults to 2 if not defined)
  • cache (Optional): Define cache expiration value in seconds (defaults to 1200 if not defined)

Note that by default the sensor is only polled once every 15 minutes. This means with the median=3 setting, it will take as least 30 minutes before the sensor will report a value after a Home Assistant restart. As the values usually change very slowly, this isn’t a big problem. Reducing polling intervals will have a negative effect on the battery life.
