# Example configuration.yaml entry
sensor:
platform: temper
name: 'My TEMPer'
scale: 1
offset: 0
```

Since some of these sensors consistently show higher temperatures the scale and offset values can be used to fine-tune your sensor.
The calculation follows the formula `scale * sensor value + offset`.

The TEMPer sensors can only be accessed as root by default. To fix the USB permissions on your system create the file `/etc/udev/rules.d/99-tempsensor.rules` and add the following line to it:

```
SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="0c45", ATTRS{idProduct}=="7401", MODE="666"
```

After that re-plug the device and restart Home Assistant.
