+The `lcn` sensor platform allows the monitoring of the following [LCN](http://www.lcn.eu) data sources:
+
+- Variables
+- Regulator setpoints
+- Thresholds
+- S0 inputs
+- LED states
+- Logic operation states
+
+The sensor can be used in automation scripts or in conjunction with `template` platforms.
