When cabling is not really needed for performance reasons, wireless monitoring is a good choice for large scientific facilities like particle accelerators, due to the quick implementation. There are several wireless flavors: ZigBee, WiFi etc. depending on requirements of specific application. In this work, a wireless monitoring system for EPICS based on an Android device is presented. The task is to monitor the vacuum control system of ISHN project at ESSBilbao, where control system variables are acquired over the network and published in a mobile device. This allows the operator to check process variables everywhere the signal spreads. In this approach, a Python based server is continuously getting EPICS variables via CA protocol and sending them through a WiFi network using ICE middleware, a toolkit oriented to develop distributed applications. Finally, the mobile device reads and shows the data to the operator. The security of the communication is ensured by a limited WiFi signal spread, following the same idea as in NFC for larger distances. With this approach, local monitoring and control applications are easily implemented, useful in starting up and maintenance stages.
