master.py needs manual start

I have 4 PiBecon units running and all except one work fine.

The "problematic" one works once I manually restarted master.py through SSH via the plugin. Once that is done it works without any issues.

I tried to send the command that I pulled from the terminal (cd /home/pi/pibeacon;nohup sudo /usr/bin/python master.py &) and tried to send it via command trough the socket but that doesn't work.

Is there a command that is can send scheduled (through socket) to keep the Pi working or is there something I can do on the Pi (chron-job)?

Thank you very much for the help (and of course the great plugin)
