This collects weather station data and makes it available in an MQTT subtree. To use your ARWN setup, you must already have configured the [MQTT](mqtt) platform. Then add the following to your `configuration.yaml` file: ```yaml # Example configuration.yaml entry sensor: - platform: arwn ``` Currently all temperatures, barometers, moisture, rain, and wind sensors will be displayed.
