Plant Monitor
This plant
integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] lets you merge moisture, conductivity, light intensity, temperature and battery level for a plant into a single UI element. It also supports setting minimum and maximum values for each measurement and will change its state to “problem” if it is not within those limits.
Configuration
To use your plant
sensor in your installation, add the following to your configuration.yaml
The configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file.
After changing the configuration.yaml
The configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file, restart Home Assistant to apply the changes.
# Example configuration.yaml entry
plant:
name_of_your_plant:
sensors:
moisture: sensor.my_sensor_moisture
battery: sensor.my_sensor_battery
temperature: sensor.my_sensor_temperature
conductivity: sensor.my_sensor_conductivity
brightness: sensor.my_sensor_brightness
min_moisture: 20
Configuration Variables
Set by you and is used by the integration as the entity_id
.
List of sensor measure entities.
Moisture of the plant. Measured in %. Can have a min and max value set optionally.
Battery level of the plant sensor. Measured in %. Can only have a min level set optionally.
Temperature of the plant. Measured in degrees Celsius. Can have a min and max value set optionally.
Conductivity of the plant. Measured in µS/cm. Can have a min and max value set optionally.
Minimum conductivity level before triggering a problem.
Maximum conductivity level before triggering a problem.
Minimum brightness before triggering a problem. In contrast to the other values, this check is not looking at the current situation, but rather at the last days. A problem is only reported if the maximum brightness over the last days was lower than min_brightness
. You can use this to check if the plant gets enough light during the course of the day.
Examples
Using plain MQTT sensor to get the data
This is a practical example that uses a multiple of MQTT sensors
to supply the readings used by the plant
sensor.
Another good source of this data would be the Mi Flora integration.
If the sensor data is within the min/max values the status will be ok
, if not the status will be problem
. You can use this to trigger a notification, if there is a problem with your plant. Of course you can only monitor attributes of your plant, where the sensor is configured and is providing the data.
Data source
The main sources of the data will usually be a MiFlora sensor or a MQTT sensor receiving the data from a PlantGateway
If you want to get the date via a PlantGateway, this is a typical configuration for the MQTT sensors:
# Example configuration.yaml entry
plant:
simulated_plant:
sensors:
moisture: sensor.mqtt_plant_moisture
battery: sensor.mqtt_plant_battery
temperature: sensor.mqtt_plant_temperature
conductivity: sensor.mqtt_plant_conductivity
brightness: sensor.mqtt_plant_brightness
min_moisture: 20
max_moisture: 60
min_battery: 17
min_conductivity: 500
min_temperature: 15
sensor:
- platform: mqtt
name: my_plant_moisture
state_topic: my_plant_topic
value_template: "{{ value_json.moisture | int }}"
unit_of_measurement: "%"
- platform: mqtt
name: my_plant_battery
state_topic: my_plant_topic
value_template: "{{ value_json.battery | int }}"
unit_of_measurement: "%"
- platform: mqtt
name: my_plant_temperature
state_topic: my_plant_topic
value_template: "{{ value_json.temperature | float }}"
unit_of_measurement: "°C"
- platform: mqtt
name: my_plant_conductivity
state_topic: my_plant_topic
value_template: "{{ value_json.conductivity | int }}"
unit_of_measurement: "µS/cm"
- platform: mqtt
name: my_plant_brightness
state_topic: my_plant_topic
value_template: "{{ value_json.brightness | int }}"
unit_of_measurement: "Lux"
You have to replace the state_topic
with the value that you configured in the PlantGateway. It also depends on the global configuration of your MQTT server.
