InfluxDB Sensor

The influxdb sensor allows you to use values from an InfluxDB database to populate a sensor state. This can be use to present statistic about home_assistant sensors if used with the influxdb history component. It can also be used with an external data source.

To configure this sensor, you need to define the sensor connection variables and a list of queries to your configuration.yaml file. A sensor will be created for each query:

# Example configuration.yaml entry
sensor:
  - platform: influxdb
    queries:
      - name: mean value of foo
        where: '"name" = ''foo'''
        measurement: '"°C"'

Configuration variables for the server:

host (Optional): IP address of your database host, eg. 192.168.1.10. Defaults to localhost.
port (Optional): Port to use. Defaults to 8086.
username (Optional): The username of the database user.
password (Optional): The password for the database user account.
ssl (Optional): Use https instead of http to connect. Defaults to false.
verify_ssl (Optional): Verify SSL certificate for https request. Defaults to false.
queries array (Required): List of queries
- name (Required): The name of the sensor.
- unit_of_measurement (Optional): Defines the units of measurement of the sensor, if any.
- measurement (Required): Defines the measurement name in InfluxDB (the from clause of the query).
- where (Required): Defines the data selection clause (the where clause of the query).
- value_template (Optional): Defines a template to extract a value from the payload.
- database (Optional): Name of the database to use. Defaults to home_assistant.
- group_function (Optional): The group function to be used. Defaults to mean.
- field (Optional): The field name to select. Defaults to value.

Examples

Full configuration

The example configuration entry below create two request to your local InfluxDB instance, one to the database db1, the other to db2:

select last(value) as value from "°C" where "name" = "foo"
select min(tmp) as value from "%" where "entity_id" = ''salon'' and time > now() - 1h

sensor:
  platform: influxdb
  host: localhost
  username: home-assistant
  password: password
  queries:
    - name: last value of foo
      unit_of_measurement: °C
      value_template: '{{ value | round(1) }}'
      group_function: last
      where: '"name" = ''foo'''
      measurement: '"°C"'
      field: value
      database: db1
    -  name: Min for last hour
      unit_of_measurement: '%'
      value_template: '{{ value | round(1) }}'
      group_function: min
      where: '"entity_id" = ''salon'' and time > now() - 1h'
      measurement: '"%"'
      field: tmp
      database: db2
