The `InfluxDB` sensor allows you to use values from an InfluxDB database to populate a sensor state.
The `InfluxDB` sensor allows you to use values from an [InfluxDB](https://influxdb.com/) 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.
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:
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](/topics/templating/) 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.

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`
