Simple Weather Bash Script

This simple weather bash script was written with the intention of piping it to a text to speech program such as flite or festival. However, it can be used for any sort of text notification such as printing to the command line or emailing.

x10 Rain8II sprinkler weather scripts for use with Heyu

I use Heyu-2.9.1 for X10 home automation running on a Sheevaplug. For irrigation, I purchased a Rain8II from WGL Designs some time ago. With the Rain8II you need an X10 ON, and OFF for each zone to control it, unlike the first Rain8 where you just needed to trigger the first zone and it would automatically go through it’s watering cycle. The Rain8II is also 2-way X10. That means you can configure it to automatically send back a status message to confirm that is has received the command that an x10 device has sent it.

The Rain8II states in the manual that it can be controlled by an X10 Mini Timer schedule, which I’ve done. When you want to disable the schedule, due to rain for example, you simply slide the selector from ‘Run’ to ‘Set Clock’ and it disables the first 5 unit codes. In my case I am only using 5 sprinkler zones so this worked out perfect. If you want to disable all 8 zones on the Rain8II, you will need to change the house code on the Mini Timer to an unused house code.

I mostly use the CM11a and Heyu for my Rain8II timers. Only when my CM11a cable went bad, I used the Mini Timer until I replaced the cable. I simply created the proper macros and timers in the schedule file an uploaded them to the CM11a. Well since I have a LOT of x10 signals flying around my house, some of the x10 signals for the Rain8II were being missed. According to the Heyu man pages, the solution for this was to simply schedule it twice a minute apart. So I have two ON and two OFF timers for all five zones. This works great, but I still have to comment out the timers and re-upload the schedule file on unexpected rainy days I don’t want to water, and remember to reverse that when I am ready to water according the regular schedule again. Also, since the Rain8II sends back confirmation messages to Heyu, I shouldn’t need two entries per ON and OFF for each zone in the schedule file!

With Heyu-2.9.1, the module type RAIN8II was added, as well as the module option ‘DEFER’. What DEFER does, is it makes Heyu wait until it receives back the Status message from the module before updating it’s internal state tables. So now you can send the command ‘heyu status backyard_grass’ and it will give you a guaranteed result. I also recently learned that you can trigger heyu scripts in the x10.conf file with CM11a uploaded timers using the ‘sndm’ flag in your script. If you use Heyu, you should know what the transmission flags are.

All that being said, I wanted a way so that my sprinkler timers would work with only the CM11a in case my Sheevaplug is down for some reason. I also wanted to be able to supplement the CM11a timers with a little intelligence when the Sheevaplug and heyu were up and running, which they are most of the time.

The first goal here is to create a status checking script so that I can eliminate the two timer schedules per x10 signal per zone that I currently have uploaded to the CM11a. I only want one timer entry per signal!

The second goal is to create a rain checking script, so that sprinklers won’t turn on if it is raining, or has rained in the last X number of days. It would be so cool if I could calculate evapo-transpiration in the script, but that is a pipe dream for now.

So far, I have a first draft of the weather script created and as of tonight it worked! (it is raining a bit at the moment).

I still need to create the status checking script. I will update this blog as I get to it.

I hope some of you shell scripting and heyu experts can offer corrections and advice!

It appears that pasting my code has messed it up a bit, need to figure that out…

Well I got a sheevaplug. I don’t feel like writing now so I’ll update this as I feel like it.

Linux Voice Recognition and Speech Home Automation

Here is a video I made for the Syno contest:

Please read more!!

I was able to successfully cross-compile and run Julius Voice Recognition Engine on my Synology DS209.

I am working on trying to compile Festival w/ MBROLA engine in place of Flite for better TTS voices. I am also looking at Cepstral and AT&T Natural Voices.

Another good program to look at would be DomotiGa + Gambas for linux HA.

Flite TTS on a Synology NAS

I was able to successfully cross compile a text-to-speech engine called Flite which is very lightweight to run on my DS209j. This means you can use HEYU or Misterhouse to output speech upon an event.

Here is my config file generated from running configure:

root@xubuntu-vm:/usr/local/flite-1.3-release# cat config/config
# -*- makefile -*-
# This file is automatically generated by configure.
# Do not hand edit.

TARGET_OS = linux-gnu
TARGET_CPU = powerpc
HOST_OS = linux-gnu
HOST_CPU = powerpc

CC = /usr/local/powerpc-linux/bin/powerpc-linux-gcc
CFLAGS = -I/usr/local/powerpc-linux/include -Wall

AR = /usr/local/powerpc-linux/bin/powerpc-linux-ar
RANLIB = /usr/local/powerpc-linux/bin/powerpc-linux-ranlib
INSTALL = /usr/bin/install -c

M68KCC =




MMAPTYPE = posix

FL_LANG = usenglish
FL_VOX = cmu_us_kal16
FL_LEX = cmulex

prefix = /usr/local
exec_prefix = ${prefix}
INSTALLBINDIR = ${exec_prefix}/bin
INSTALLLIBDIR = ${exec_prefix}/lib
INSTALLINCDIR = ${prefix}/include/flite

Misterhouse on Synology NAS


I’ve confirmed that misterhouse does work with /dev/usb/ttyUSB0.

I recommend unzipping Misterhouse in /usr/local

DiskStation> cd /usr/local
DiskStation> gunzip < /volume1/Downloads/misterhouse-2.105.tar.gz | tar xvf -

Make sure you run the configure which uses h2ph. h2ph is just a perl script, but you have to make sure you download the your systems GPL source from Synology and change one line in the Misterhouse configure script:

#cd /usr/include
cd /usr/local/powerpc-linux/include

When you run the script it will remove all Windows files and will use the C header files to produce Perl header files ending in .phFollow this: this: /usr/local/mh/bin create a file called mh.private.ini and add these basic entries:

zip_code= 12345

Now when you start Misterhouse do something like this to run it in the background and have its output go to some logfile:

DiskStation> cd /usr/local/mh/bin
DiskStation> ./mhl & > /var/log/mh.out

Now you should be able to go to http://192.168.x.x:8080 and access Misterhouse.Please read the Misterhosue docs from here…

CM11a, Heyu, and domus.Link running on Synology NAS

I have an old HD11a which is just a re-branded CM11a, and I verified that it does work through the usb/serial converter I have.

Using optware ipkg (ipkg is a must!) I was able to install HEYU. They also have one called Ppower or Penguin Power, which I assume would also work:

DiskStation> ipkg list | grep "home automation"
heyu - 2.8.0-1 - X10 home automation control using the CM11A
ppower - 0.1.5-1 - Ppower, short for 'Penguin Power', is a piece of software for controlling x10 home automation equipment connected to the comput

domus.Link PHP frontend for HEYU

I wasn’t too excited about cgi/perl scripts, but I found what I think is one of the only PHP front ends which runs perfectly on the Syno after slight tweaking of the php.ini file.


I was even able to create a 3rd-Party applications node for it to run embedded in the web manager.

DiskStation> pwd
DiskStation> ls -laR domusLink/
drwxr-xr-x 2 root root 4096 Dec 23 00:53 .
drwxr-xr-x 3 root root 4096 Dec 23 00:33 ..
-rw-r--r-- 1 root root 198 Dec 23 01:01 application.cfg
lrwxrwxrwx 1 root root 44 Dec 23 00:53 images -> /volume1/web/domus.Link/theme/default/images

DiskStation> cat application.cfg
text_enu = domus.Link
description_enu = domus.Link - Home Automation Interface
type = embedded
protocol = https
port = 443
path = /domus.Link
