 You need to configure every button to make it work with Home Assistant. First connect the Wifi Buttons to your wireless network. Keep in mind that they only support WPS (Wi-FI Protected Setup). Once a button is connected you have three minutes to set the actions for the push patterns. The fastest way is to use `curl`. Check the [documentation](https://mystrom.ch/wp-content/uploads/REST_API_WBP.txt) of the WiFi Button for further details about the implementation (`http://` is replaced by `get://` or `post://`). `action` is the name of the corresponding push pattern (see above).
