The X10 interface uses the Python X-10 library to talk to the X10 interfaces. While Python X10 does support the CM11/12, CM15, and CM17a interfaces, only the CM11 has been tested and functionality for the others has been added but have not been tested. Send a message to 'dinki' on the forums or IRC if you are interested in using these other interfaces.
The X10 device driver reads from a configuration file located at /etc/opt/agocontrol/conf.d/x10.conf:
[x10] interface=CM11 device=/dev/ttyUSB0 switches=A2,A3,B3,B4,B5,B9,B12,B16 dimmers=D1
Interface options are CM11, CM15, and CM17a. Note that the CM12 is supported using the CM11 option
Switches are supported for simple on/off and are known working. These switches can be used for lamp, appliance, motion detectors, remote control buttons, etc. Dimmer support has been added but has not been tested.
Python X-10 only supports sending X10 commands. This device driver has been given a limited, but functional access to commands received on the X10 interface via RF->Powerline communications. The device driver only recognizes on/off commands received. All other RF commands, such as dimming, are simply ignored.
Follow the instructions at http://www.cm19a.com/2013/02/python-x10-cm19a-usb-software-linux.html for installing and testing the interface. Once you have everything working, copy 'CM19aDriver.py', 'CM19aProtocol.ini', 'logger.py' to /opt/agocontrol/bin/ .
Download my driver at http://pastebin.com/kGaC938c and copy it to /opt/agocontrol/bin as 'agox10-cm19a.py'. Note that this driver is a mess as it's still a work in progress, but it does work well. Bright/Dim does not work yet, but ON/OFF works fine. Also, this version does not read from a config file so edit your switches/dimmers in the 'agox10-cm19a.py' code.
Set permissions on all copied files as necessary. Try running /opt/agocontrol/bin/agox10-cm19a.py . It should start up and start watching/sending RF commands. Once you are satisfied, you can create a service to start the device automatically.
