#### Entries as CSV
Assuming the log file contains multiple values formatted as CSV like shown below:
```text
timestamp,temperature,humidity
1631472948,21,39
1631472949,22,36
```
This would require the following entry in the `configuration.yaml` file to extract the temperature:
{% raw %}
```yaml
# Example configuration.yaml entry
sensor:
- platform: file
name: Temperature
file_path: /home/user/.homeassistant/sensor.csv
value_template: '{{ value.split(",")[1] }}'
unit_of_measurement: "°C"
```
{% endraw %}
