Attention!
Immediately after a method has been called or an event has been triggered you should poll the value
in the property LastState. Otherwise the property LastState could be overwritten by another method,
as only the status message from the last method run is given in the property LastState. This warning
also applies to internal methods that run in the background and that are not started by you.
