 ## Example usage of the module
 The sample below shows how to use this Python module (api for wpm heat pumps).
 
 ```python
+    import asyncio
     from pystiebeleltron.wpm import WpmStiebelEltronAPI, WpmSystemParametersRegisters
 
-    api = WpmStiebelEltronAPI('IP_ADDRESS_ISG')
-    await api.connect()

+      await api.connect()
 
-    await api.async_update()
