We are a small hydro-power electricity supplier near Vienna. Our customers expect electricity around the clock with a very high service level agreement. It is easy to derive that service times are very important to us. Huge monitors were installed that should show the current service message.

• "Everything operates as expected" is the default message.
• But a service operator can set the message manually to something else (e.g., "Service checks: No power until 5:00 pm").
• A service operator can also reset the message to its default message.
