X1OKAKU 5 X1OKAKU 5 NAME x10kaku KaKu and HomeEasy receiving support for HEYU DESCRIPTION Heyu is an X10 Automation program for Linux Unix and Mac OS X See man page heyu 1 for usage information KaKu and HomeEasy remote controls transmit encoded RF signals which operate switch and dimmer mod ules When equipped with a compatible RF receiver Heyu can receive and decode this information SYSTEM REQUIREMENTS Receiving KaKu and HomeEasy signals with Heyu requires a 433 92 MHz RFXCOM X10 RF receiver and Heyu version 2 8 or greater COMPILER OPTION Support for KaKu HomeEasy remotes is compiled into Heyu by default A compiler option can be used to omit this support See the file INSTALL included in the Heyu distribution source directory for details CONFIGURATION It is assumed that a working installation of Heyu version 2 8 or greater exists on the computer and that the user has a basic familiarity with Heyu Include the following directive in the Heyu configuration file TTY_AUX lt serial_port gt RFXCOM where lt serial_port gt is the port where the RFXCOM receiver is connected The RFXCOM receiver con nects to a USB port but includes a USB gt Serial converter chip At least under Linux the serial port will have the form dev ttyUSBn where n 0 1 2 etc Configure your KaKu HomeEasy receiver modules with the remotes according to the user manual In gen eral this involves pressing the Learn button on the receiver until
