This is how I solved it!

The script that show status on homepage.

<?php
echo "<b>Machine status</b>";
echo "</br>";
$arr = array(5, 7, 9);
foreach ($arr as &$value) {
 
$get_data = "http://10.0.20.11/json.htm?type=command&param=getuservariable&idx=".$value;
$result = file_get_contents($get_data);
$decode = json_decode($result,true);
 
	if ($decode["result"][0]["Value"] == "1"){
 
	$icon = "green-icon.png";
	}
	else {
	$icon = "red-icon.png";
	}
 
switch ($decode['result'][0]['Name']) {
    case "washingmachine_status":
        $unit = "Washing machine";
        break;
    case "dryer_status":
        $unit = "Dryer";
        break;
    case "dishwasher_status":
        $unit = "Dishwasher";
        break;
}
 
 
 
	echo "</br>     " . $unit . "</br><img src=\"/wp-content/uploads/2015/12/" . $icon . "\"><em>" . $decode['result'][0]['LastUpdate'] . "</em><br>";
 
}
?>

The script that check my machines.

I have a solution, this is how i manage solve this “irritating problem”.

I assume that you have a Z-wave base, mine is a raspberryPi with a razberry chip and with software domoticz.

You shoppinglist:
1pcs Inline Smart Energy Switch from Aeon Labs
1pcs Motion sensor from Fibaro
In sweden you can get all you need at www.m.nu

Aeon Labs – Switch

Fibaro motion sensor

 

And I use a LUA script named script_time_PIR-tv.lua. So after 20 minutes of inactivity in livingroom, the tv shutsdown… Simply as that!

 
function timedifference(s)
year = string.sub(s, 1, 4)
month = string.sub(s, 6, 7)
day = string.sub(s, 9, 10)
hour = string.sub(s, 12, 13)
minutes = string.sub(s, 15, 16)
seconds = string.sub(s, 18, 19)
t1 = os.time()
t2 = os.time{year=year, month=month, day=day, hour=hour, min=minutes, sec=seconds}
difference = os.difftime (t1, t2)
return difference
end
 
commandArray = {}
 
-- Set length of time light should be on for in seconds
timeon = 1200
-- Calculate time since time PIR was last activated
difference = timedifference(otherdevices_lastupdate['Vardagsrum motion'])
-- If the time since last activation was within 1 minute of time for light to stay on
if (difference &gt; timeon and difference &lt; (timeon + 61)) then
tempdiff = tostring(difference)
tempmessage = "Switch1 Light Off - after at least " .. (timeon+1) .. "secs up - actually - " .. tempdiff .. "seconds"
print(tempmessage)
-- Switch off Switch1
commandArray['Tv'] = 'Off'
end
 
return commandArray

 

I have logging my outside temperature since 2007 and reporting it to the swedish temperature page www.temperature.nu with a uptime of 98%. It’s pretty good I must say.
I’m used 1-wire to do this but today I have shifted to wireless insteed. Why is becuse that my 1-wire have been so long in meters and act like a antenna when we have thunder, so the result is that almost all my
component have fried.

So today after some programming, I now done with this installation of two wireless THGN132N sensors placed one at north and one at southeast.
As a receiver I’m using a raspberryPi with domoticz and a RFXtrx433E USB 433.92MHz Transceiver connected.

And this script take the lowest temperature and the temperatur.nu collect it from it’s textfile.

<?php

$north = exec(“wget -O – -q http://10.0.20.11/utenorr.txt”);
$east = exec(“wget -O – -q http://10.0.20.11/uteost.txt”);

if ($north < $east){
$lowest = “North”;
$temp = $north;
}
else{
$lowest = “East”;
$temp = $east;
}

echo “$lowest har lgst temp: $temp grader”;

exec(“echo ” . $temp . ” > /home/essunga/public_html/wwwroot/temperature_lowest.txt”);

?>

 

 

My webbserver act as a torrentclient as well.

To start rtorrent in background I using the command screen to do this.

This is how I do:
In terminal type,

bash-4.2$ screen -dmS rtorrent rtorrent

Your have now started rtorrent in a screen named rtorrent, how to access is just type

bash-4.2$ screen -r rtorrent

and there you have it.
And to exit, hold on Ctrl and A release and then press D. Now your are out of rtorrent screen and it still running i background.

Are you like me that you have a habbit to listen to music when programming in linux and you struggle with mplayer to stream a radiostation?

In your home folder your have a file that names .bashrc if your don’t have one just create one. That file in loaded when you log on and here you can create short commands.

Mine look like this.
.bashrc

alias litefm='mplayer -playlist http://www.litefm.se/live.m3u'
alias radioseven='mplayer -playlist http://www.radioseven.se/128.pls'
alias xterm='xterm -bg black -fg white'
alias jonathan='cvlc http://10.0.20.7/mjpg/video.mjpg &'
alias framsidan='cvlc http://10.0.20.8/mjpg/video.mjpg &'

Add these line to your file and logout and now login and try command litefm in your terminal. And now your are streaing a radiostation from Trollhättan – Sweden.

I builded a digital photo frame in 2012 with a old TFT-screen 17″ that I had lying around.
Here comes a post about how I did it, and sharing my scripts…

Here is a video and the photo frame have a uptime for three years now.

Guide from clean install of raspbian – using 2015-05-05 version.

pi@fotoram ~ $ sudo apt-get update
pi@fotoram ~ $ sudo apt-get upgrade

Now you have the latest version of your raspbian.

Now we have to install feh. Feh is the program that display the pictures and installing php, because we are using some php-scripts.
And at least, sendmail. Because after we email a picture, we get a respond from the photoframe that the picture is received.

pi@fotoram ~ $ sudo apt-get install feh php5-cli php5-imap sendmail

Download the scripts.
PhotoFrame.zip

Okey, how does this work? First we have to disable screensaver, otherwise the screen will shutdown.

Stop text terminals from blanking
change in /etc/kbd/config these two:
BLANK_TIME=0
POWERDOWN_TIME=0

Stop Xsession from blanking
Add these lines to /etc/xdg/lxsession/LXDE-pi/autostart or /home/pi/.config/lxsession/LXDE-pi/autostart
@xset s noblank
@xset s off
@xset -dpms
and comment out line @xscreensaver -no-splash to
#@xscreensaver -no-splash

In the photoframe.zip file we have a couple of files.

bilder = folder there feh will look for pictures.
display.txt = textfile with information that will display in the bottom corner.
fetch_mail.php = A php script that fetch new pictures from gmail.
get_online_pics.sh = A script that fetch webcam pictures from the internet and put it to the bilder folder.
picslide.sh = Script that start feh at boot.
put_display.sh = Update the information in display.txt file
run_fetch_mail.sh = Script that run fetch_mail.php, I made it because sometimes it take some time to fetch a new picture from gmail. And if the service is running the system hangs. So this script look if the fetch_mail.php is running, and if it does. It won’t start a new one.

Now everything is installed and the scrips are in pi homefolder.

Now add these lines to cron.
First I like pico as a editor insteed of vim.
So change the editor

pi@fotoram ~ $ which pico  # Output /usr/bin/pico
pi@fotoram ~ $ export EDITOR=/usr/bin/pico

Now run

pi@fotoram ~ $ crontab -e

Add following lines:

*/1 * * * * /home/pi/get_online_pics.sh > /dev/null 2>&1 # Get a new pictures from webcam
*/1 * * * * /home/pi/put_display.sh > /dev/null 2>&1 # Update display.txt
*/5 * * * * /home/pi/run_fetch_mail.sh > /dev/null 2>&1 # Get new pictures from Gmail
00 22 * * * /opt/vc/bin/tvservice -o > /dev/null 2>&1 # Shutdown screen at 22:00
00 05 * * * sudo reboot > /dev/null 2>&1 # Reboot the Pi at 05:00 so the screen wakes up

Now we have that running, lets add so feh starts at bootup. Go back to /etc/xdg/lxsession/LXDE-pi/autostart or /home/pi/.config/lxsession/LXDE-pi/autostart and add @/home/pi/picslide.sh at the bottom save and then reboot.

As you can see in my script, that fetch_mail.php the script is only looking for new pictures in label Fotoram. So you have to make a filter in gmail. I using

Match: from:(myemailAndOneFilterforMypartnersEmail@essunga.org)
Do: Jump over Inbox, Use Label "Fotoram"

Do you have any questions or problems, please write a comment.

Here is one simple way to unzip multiple zip files in linux thru console.

bash-4.2$ for i in *.zip; do unzip -d $i.folder $i; done

Here is how I build my alarm, quite simple to do and to get push messages from prowl or mail.
For Gateway I use a moteino connected to a raspberryPi model B+ as you can see from the pictures below.

Feel free to ask questions or guidance if you want to build one by you own.

It was time for some new changes around here, and here it is. I have to do someting in my sparetime, besides programming my homeautomation and building a outside deck.

It is vacation as they say…
