miflora sensor platform allows one to monitor to plants. 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.
Start a scan to determine the MAC addresses of the sensor:
$ sudo hcitool lescan LE Scan ... F8:04:33:AF:AB:A2 [TV] UE48JU6580 C4:D3:8C:12:4C:57 Flower mate [...]
Flower care or
Flower mate entries, those are your sensor.
To use your Mi Flora plant sensor in your installation, add the following to your
# Example configuration.yaml entry sensor: - platform: miflora mac: 'xx:xx:xx:xx:xx:xx' monitored_conditions: - temperature
- mac (Required): The MAC address of your sensor.
- monitored_conditions array (Optional): The paramaters that should be monitored (defaults to monitoring all parameters).
- moisture: Moisture in the soil.
- light: Brightness at the sensor’s location.
- temperature: Temperature at the sensor’s location.
- conductivity: Conductivity in the soil.
- battery: Battery details.
- 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: 1will work fine.
- 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_value (Optional): Define cache expiration value in seconds (defaults to 1200 if not defined)
- adapter (Optional): Define the bluetooth adapter to use (defaults to hci0). Run
hciconfigto get a list of available adapters.
Note that by default the sensor is only polled once every 15 minutes. This means with the
median: 3 setting 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.
