The `apcupsd` sensor platform allows you to monitor a UPS (battery backup) by using data from the [apcaccess](http://linux.die.net/man/8/apcaccess) command.

To use this sensor platform, you first have to set up [apcupsd](/components/apcupsd/), and add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  - platform: apcupsd
    resources:
      - bcharge
      - linev
      - loadpct
      - nominv
      - nompower
      - numxfers
      - outputv
      - status
      - timeleft
      - tonbatt
```

Configuration variables:

- **resources** array (*Required*): Contains all entries to display.

Given the following output from `apcaccess`:
