 The `sma` sensor will poll a [SMA](http://www.sma-solar.com/) [(US)](http://www.sma-america.com/) solar inverter and present the values as sensors (or attributes of sensors) in Home Assistant.
 
+This sensor uses the web interface and in order to use it you have to be able to connect to the solar inverter from your favorite web browser.
