The InfluxDB sensor allows you to use values from an InfluxDB database to populate a sensor state.

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

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 (Required): List of queries

Configuration variables for the queries:

• name (Required): The name of the sensor,
• unit_of_measurement (Required): Defines the units of measurement of the sensor,
• 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, default to mean
• field (Optional): The field name to select, default to value.

{% linkable_title Minimal configuration %}

The example configuration below will create a request to influx db to the default database (home_assistant) to get the mean value of foo in measurement °C

sensor:
  - platform: influxdb
    queries:
      - name: mean value of foo
        unit_of_measurement: °C
        where: '"name" = ''foo'''
        measurement: '"°C"'

{% linkable_title Full configuration %}

The example configuration entry bellow create two request to influx db, 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
