 Escape game are opened 7 days a week and particularly booked during weekends and usually until midnight. Therefore their uptime must be close to 100% and incidents must be worked-around immediately by the game master (manual commands).
 
 Escape Room Props operation and performance impact directly escape game customer experience. Therefore notifications must be processed in human-scale real-time, automatically or manually by a non-technological user (the game master).

 Arduino with Ethernet or Wifi shield is suitable to build an Escape Room Props, however the sketch must be uploaded with an USB cable, so it is not convenient for prop design and worse for prop in production, which can lead to an unexpected significant increase in TCO.
