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 %} host: description: IP address of your database host, e.g. 192.168.1.10. required: false default: localhost type: string port: description: Port to use. required: false default: 8086 type: string username: description: The username of the database user. required: false type: string password: description: The password for the database user account. required: false type: string ssl: description: Use https instead of http to connect. required: false default: false type: boolean verify_ssl: description: Verify SSL certificate for https request. required: false default: false type: boolean queries: description: List of queries. required: true type: list keys: name: description: The name of the sensor. required: true type: string unit_of_measurement: description: Defines the units of measurement of the sensor, if any. required: false type: string measurement: description: Defines the measurement name in InfluxDB (the FROM clause of the query). required: true type: string where: description: Defines the data selection clause (the where clause of the query). required: true type: string value_template: description: Defines a [template](/docs/configuration/templating/#processing incoming data) to extract a value from the payload. required: false type: template database: description: Name of the database to use. required: false default: home_assistant type: string group_function: description: The group function to be used. required: false default: mean type: string field: description: The field name to select. required: true type: string default: value {% endconfiguration %}

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: '{% raw %}{{ value | round(1) }}{% endraw %}'
group_function: last
where: '"name" = ''foo'''
measurement: '"°C"'
field: value
database: db1
- name: Min for last hour
unit_of_measurement: '%'
value_template: '{% raw %}{{ value | round(1) }}{% endraw %}'
group_function: min
where: '"entity_id" = ''salon'' and time > now() - 1h'
measurement: '"%"'
field: tmp
database: db2
