This tellstick sensor platform allows you to get current meteorological data from a [TellStick](http://www.telldus.se/products/tellstick) device.

To use your TellStick device in your installation, add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  platform: tellstick
  135: Outside
  21: Inside
  only_named: True
  temperature_scale: "°C"
  datatype_mask: 1
```

Configuration variables:

- **ID: Name** *Optional*: Entry for a sensor with the name for it and its ID.
- **only_named** *Optional*: Only show the named sensors. Set to `True` to hide sensors.
- **temperature_scale** *Optional*: The scale of the temperature value.
- **datatype_mask** *Optional*: Mask to determine which sensor values to show based on. Please check the [TellCore tellcore.constants documentation](https://tellcore-py.readthedocs.org/en/v1.1.2/constants.html#module-tellcore.constants) for details.
