+# Omnik Inverter Binding
+
+This binding reads metrics from Omnik Solar Inverters.
+
+## Supported Things
+
+All Omniksols are expected to function, provided they have the Wifi module. At
+moment of writing the _Omniksol-3.0k-TL2_ has been tested.
+
+## Discovery
+
+No autodiscovery available
+
+## Thing Configuration
