Suggesting this link to Xiaomi's website as hopefully this page won't disappear on us, but if anyone has a better page to suggest, I'd happy with that too. Just want to limit the broken links and figured the vendor's page should be most static

The `miflora` sensor platform allows one to monitor to plants. The [Mi Flora plant sensor](https://xiaomi-mi.com/sockets-and-sensors/xiaomi-huahuacaocao-flower-care-smart-monitor/) 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:
|
|
|
|
```bash
|
|
$ sudo hcitool lescan
|
|
LE Scan ...

|
C4:D3:8C:12:4C:57 Flower mate
|
|
[...]
|
|
```
|
|
|
|
Check for `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 `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# 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 parameters 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: 1` will 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 `hciconfig` to 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.

A full configuration example could looks the one below:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
sensor:
|
|
- platform: miflora
|
|
mac: 'xx:xx:xx:xx:xx:xx'
|
|
name: Flower 1
|
|
force_update: false
|
|
median: 3
|
|
monitored_conditions:
|
|
- moisture
|
|
- light
|
|
- temperature
|
|
- conductivity
|
|
- battery
|
|
```
