The `influxdb` sensor allows you to use values from an [InfluxDB](https://influxdb.com/) 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:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
sensor:
|
|
- platform: influxdb
|
|
queries:
|
|
- name: mean value of foo
|
|
where: '"name" = ''foo'''
|
|
measurement: '"°C"'
|
|
```
|
|
|

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`
|
|
|
|
```yaml
|
|
sensor:
|
|
platform: influxdb
|
|
host: localhost
|
|
username: home-assistant
|

queries:
|
|
- name: last value of foo
