This page explains how to turn a LEAF Bering-uClibc router into a Home Automation controller using the
heyu.lrp Package. Taken from http://www.heyu.com introduction: "Heyu is a text-based console program for remotely controlling lights and appliances in the home or office. The complete source is made available under the GNU GPLv3 license. Heyu uses the CM11A computer interface to send and receive X10 control signals over the AC power lines to modules which can turn On, Off, or Dim attached lamps or appliances. It can store a schedule of timed events in the CM11A memory for execution without any more computer intervention." It is also mentioned that " Heyu supports an optional W800RF32A, MR26A, or RFXCOM RF receiver connected to a second port as an auxiliary input device for RF signals from X10 and other supported transmitters. Heyu can also use an optional CM17A interface to transmit X10 RF signals." Though what follows has only been tested on the CM11A computer interface.
The prerequisites are:
- a working LEAF Bering-uClibc 6.x router.
- a CM11A Computer interface module, some might still be available on line.
- a few X10 appliance or lamp modules.
- a serial port on your router, Heyu uses by default ttyS0.
Configure the System
Loading the Package
Load the heyu.lrp Package by adding heyu to the list of Packages specified in the leaf.cfg file on the boot media. There are no dependencies for this Package.
To start and test heyu.lrp the default configuration files /etc/heyu/x10.conf and /etc/heyu/x10.sched should work.
Test your setup
At this point you can either reboot the firewall or install
heyu.lrp manually by:
mount /dev/sdx1 /mnt # x= default to a, but could be b, c, etc, if you have other disks cd /mnt apkg -i heyu heyu
You should see something like:
Heyu version 2.11-rc1 X10 Automation for Linux, Unix, and Mac OS X Copyright Charles W. Sullivan and Daniel B. Suthers Usage: heyu [options] <command> (Enter 'heyu help' for commands.)
And check that task heyu_relay is displayed
ps 11236 root 1432 S heyu_relay
Get more info:
Heyu version 2.11-rc1 Configuration at //etc/heyu/x10.conf Powerline interface on /dev/ttyS0 Firmware revision Level = 1 Interface battery usage = Unknown Raw interface clock: Tue, Day 076, 00:51:55 (--> Civil Time: Tue 18 Mar 2014 00:51:55 UTC) No schedule has been uploaded by Heyu. Housecode = K 0 = off, 1 = on, unit 16.......8...4..1 Last addressed device = 0x0400 (0000000000001000) Status of monitored devices = 0x0000 (0000000000000000) Status of dimmed devices = 0x0000 (0000000000000000)
Now send a command to an appliance module, with address "k 5" for instance, where "k" is the housecode set in the configuration.
heyu on k5 heyu off k5
If you hear two heart warming thumbs, everything works fine... have fun !
Check again that heyu_relay is working.
Check serial port ttyS0 parameters:
stty -F /dev/ttyS0 # the speed should be 4800 bauds.
Check the CM11A is transmitting by typing:
The CM11a will transmit the letter “z” when it detects a module changing state. Plug a lamp in one of your connected module and force it to activate by switching the lamp on or off a few time you should then see the letter "z" appears every seconds on your display. You also can use an RF remote control, if you have one, to activate any module.
