Domotemp – domoticz temperature floorplan

For my home automation i’m using Home Assistant and Domoticz.
All 433Mhz Temperature/Humidity are connected to a RFXcom device on two domoticx instances. (Master slave construction)

I’ve made a php script and a bash script to draw all sensors on a floorplan in realtime.

There is also a cron running which takes a snapshot of the generated image every 5 minutes.
These images are being converted to MP4 and animated GIF to have a timelapse with all temperatures displayed on a floorplan.

An obfuscated view of the floorplan

The circles are where sensors are placed.
Colors are from blue till red, representing the heat.
In the center is the measured temperature value.

The (shortened) PHP script: (index.php)

<?php
header('Content-type: image/png');
// This is the floorplan empty ..
$png_image = imagecreatefrompng('plattegrondenmerge.png');
$white = ImageColorAllocate($png_image, 0, 0, 0);

$max = 40;
$min = -10;

// living
// getstate is a bash script (see below which gets the values from domoticz using curl) 
// 840 is the domoticz idx
$temp840 = shell_exec('./getstate 840');
// A gray circle will be drawn if the temperature age is > 500 seconds
$age = shell_exec('./new.sh 18 840 500 >/dev/null || echo gray');
// location of circle
$start_x = 950;
$start_y = 760;
$line = $temp840 + 10;
// get x-th line from colors
$colorfromlist = shell_exec("tail --lines=$line ./colors2 | head -1");
if(strpos($age, "gray") !== false){
 $colorfromlist = "128,128,128";
};
$colors = explode(",", $colorfromlist);
$color = imagecolorallocatealpha($png_image, $colors[0], $colors[1], $colors[2], 50);
// draw circle
imagefilledellipse ($png_image, $start_x, $start_y, 175, 175, $color);
$start_x = $start_x - 70;
$start_y = $start_y + 15;
// add text
imagettftext($png_image, 24, 0, $start_x, $start_y, $white, './verdana.ttf', $temp840);

// winecellar
$temp840 = shell_exec('./getstate 839');
$age = shell_exec('./new.sh 18 839 700 >/dev/null || echo gray');
$start_x = 560;
$start_y = 840;
$line = $temp840 + 10;
$colorfromlist = shell_exec("tail --lines=$line ./colors2 | head -1");
if(strpos($age, "gray") !== false){
 $colorfromlist = "128,128,128";
};
$colors = explode(",", $colorfromlist);
$color = imagecolorallocatealpha($png_image, $colors[0], $colors[1], $colors[2], 50);
imagefilledellipse ($png_image, $start_x, $start_y, 175, 175, $color);
$start_x = $start_x - 70;
$start_y = $start_y + 15;
imagettftext($png_image, 24, 0, $start_x, $start_y, $white, './verdana.ttf', $temp840);

// ETC ETC

imagesavealpha($png_image, TRUE); 

  imagepng($png_image);
  imagedestroy($png_image);
?>

getstate bash script
(gets the temperature from domoticz instance1 given an idx)

#!/bin/bash
curl -s --connect-timeout 2 --max-time 5 "http://ip-domoticz1:8080/json.htm?type=devices&rid=$1" | egrep "Temp|Humid" | awk '{print $3 }' | cut -f1 -d\. | grep -v \" | tr -d "\n\r" | sed s/,/%\ /g | awk '{ print $2"° "$1 }'

new.sh script gets the age of the reading from
domoticz1 or domoticz1
Usage: ./new.sh <domoticz-last-numer-ip> <idx> <maxageinseconds>

#!/bin/bash
## server idx time
now=$(date +%s)
lastupdate=$(curl -s -i -H "Accept: application/json" "http://192.168.1.$1:8080/json.htm?type=devices&rid=$2" |  grep LastUpdate | cut -f4 -d\" )
#echo $lastupdate
seen=$(date -d "$lastupdate" +%s)
#echo $seen
#echo "$(( $now - $seen))"
difftime="$(( $now - $seen))"
if [ $difftime -gt $3 ] ; then
  echo "WARN : too old - $difftime seconds"
  exit 1
else
  echo "OK : $difftime seconds"
  exit 0
fi

Garbage display

I wanted to know when trash is being collected. So i made a dual led thingy.

Version without lid .. just to test

When we lived in Utrecht, the website which mentions when, what is collected was easy .. like a API

We live in Hilversum now, so i had to write a scraper.

UPDATE : Script not working anymore. Site has been changed, and I’m not willing to run a headless browser (phantomjs) to scrape the info

See below my new solution

Script to set leds

#!/bin/bash
set -x

curl  http://10.1.0.46/control?cmd=NeoPixel,2,0,0,0
exit 0
fi


set -x
if [ $1 = "GFT" ] ;then led1="150,0,0" ;fi
if [ $1 = "Rest" ] ;then led1="150,150,150" ;fi

Update new solution

My home assistant has a hacs addon installed which does the heavy lifting for me.
Why not use this info?

I wrote about NR and HA here

Home Assistant/NodeRed update

So getting the info for NR to parse:

I only need to use the lightblue node bottom right!

It is the current state node, inject a timestamp every day to get new values.
Parse this and send using Mqtt to my Led display thingy

Arpscanner

Changed stuff in my arpscanner

I want to know whats on my network, and be informed when a alien device connects.
This also helps me gathering all devices and macaddresses for a cmdb.

I’ve got below in my crontab

5 * * * * root /usr/local/bin/arpscanner

And the script:

#!/bin/bash
# Using a scanner on a specific vlan/interface
arp-scan -l -g  -I p1p1.10 | grep ^10 | grep -vi packets > /var/log/arpscanner
cat /var/log/arpscanner | awk '{ print $2 }'| while read ; do
grep $REPLY /var/local/arpscanner.lst >/dev/null || echo $REPLY | mail -s arpscanner henri@henriaanstoot.nl
done

New and checked devices i put in the file mentioned above:

Mount Taranaki New Zealand

While traveling New Zealand we went to see Mt Taranaki

Mount Taranaki (Māori: Taranaki Maunga), also known as Mount Egmont, is a dormant stratovolcano in the Taranaki region on the west coast of New Zealand’s North Island. It is the second highest point in the North Island, after Mount Ruapehu.

I made this timelapse using a Nikon D750.

X-plane on linux

Starting x-plane can be a problem on Linux when screens are not properly detected. (Like order of screens or sizes)

Below is a three-screen start script for Linux.

#!/bin/bash
#Will start a three screen xplane session
#Screen are @ 1920x1080 resolution
numscreens=3
count=0
if [ -z $1 ] ; then
./X-Plane-x86_64 --monitor_bounds=0,0,1920,1080,1920,0,1920,1080,3840,0,1920,1080
 while [  $count -lt $numscreens ]; do
    sleep 1
    count=$( wmctrl -l | grep X-System | wc -l)
 done
fi
screencount=1
wmctrl -l | grep X-Syst |awk '{ print $1 }' | while read ; do 
	wmctrl -i -r "$REPLY" -T "X-System_$screencount"
	let  screencount=screencount+1
done
wmctrl -r "X-System_1" -e 1,0,0,1920,1080
wmctrl -r "X-System_2" -e 1,1920,0,1920,1080
wmctrl -r "X-System_3" -e 1,3840,0,1920,1080

Fun with Xrandr

Leave a comment

xrandr is an official configuration utility to the RandR (Resize and Rotate) X Window System extension. It can be used to set the size, orientation or reflection of the outputs for a screen.

Someone broke my screen at a hackers event. The terminal was really hard to read with the black parts, so i tilted the screen

Broken screen in 2013

Quiet friday at work, playing with my little trusty 2530p.
I’m using xmonad, so i don’t need any fancy work laptop.

Fun with distorting the screen

Another quiet friday at work, working from home, i turned all monitoring displays upside-down, sideways, or rotated them every so much seconds.

While this is a lot of fun to use, i used this to get my monitorsetups exactly the way i wanted, at home or at work.
Different screen sizes, height differences .. no problem.

A fun tool to use is:

HS 500 APC Ups to domoticz

Leave a comment

A friend of mine wanted to monitor his UPS using domoticz.
This UPS only had a simple web interface with information.

So we needed to scrape this information and push this into domoticz.

First create a dummy device in domoticz and note its IDX.

Then we can scrape needed information using below script.

#!/bin/bash
#set -x
# Domoticz server
SERVER="127.0.0.1:8080"

# APC Back-UPS HS 500 status URL
UPS="http://IP-OF-UPS/status.cgi"

# The number of the IDX in the list of peripherals
IDX="362"

# Path for temporary file (RAM drive)
TMPFILE="/tmp/apc-hs500-status.txt"

# Get APC Back-UPS HS 500 status and write to temporary file
wget $UPS -O $TMPFILE 2>/dev/null
if [ $? = 0 ]
then
PWR=$(cat $TMPFILE| tr -dc '[[:print:]]' |awk -F"Watts" '{print $1}' |rev |cut -f1 -d\> |rev |cut -f1 -d\&)
fi

if [ $PWR ]
then
echo "Load on Battery in Watts: $PWR"
# Send data to Domoticz
curl -s -i -H "Accept: application/json" "http://$SERVER/json.htm?type=command&param=udevice&idx=$IDX&nvalue=0&svalue=$PWR"
PWR=""
fi
rm $TMPFILE

Terminals and SSH

Leave a comment

I’m using a lot of terminals, spawning a new terminal and running ssh, without knowing if i still have a session running.

Lets see:

This was done using something like:

#!/bin/bash
count=$(ps -ef | grep xterm | grep -v grep | wc -l)
timestamp=$(date +%s)
echo "$timestamp,$count" >> /var/local/terminallog

Later i made a script to push this information in Grafana

Now for the SSH part.
I’m jumping from machine to machine using ssh, sometime i loop back to a server i was already connected to .. this helps me to keep track

in ssh_config add
SendEnv SSHTRAIL

in sshd_config add
AcceptEnv SSHTRAIL

in /etc/profile
export SSHTRAIL=$SSHTRAIL:$HOSTNAME

restart sshd
when you do this on all your machines you can get a trail of ssh using:
echo $SSHTRAIL
workstation:server1:server66:server1

I could change the prompt when a loop is detected
echo $SSHTRAIL | sed -e 's/:/\n/g' | sort | uniq -c | grep -v 1 | ... | echo "WARNING: loop in ssh"

Planning for a Cocktail night

Leave a comment

I love making cocktails for my ladies, but for the occasional drink, now for a cocktail night.

See my other post about my cocktail bar in another post.

30th Juli I’m entertaining Arja, Coline and Monique by serving cocktails.

So i made a little list of cocktails to choose from.
I say choose, i could not have guessed i’d have to make them all!

One page of the cocktail list, with scorecards

So i made a little generator

Using a blank template png and a bash script i generated above.

#!/bin/bash
cp cocklist-leeg.png 1.png

ls drinks | sort -n  | grep -v totallist | while read drink; do
if [ $(echo $drink | cut -c-2 ) -gt 90 ] 
then 
	color="#ffcc00"  
else 
	color="#ff7406" 
fi
convert -font Impact.ttf -fill "$color" -pointsize 43 -annotate +$xstart+$ystart "$(echo $drink | cut -c3- )" 1.png 2.png
echo $drink

ystart2=$[$ystart + $yspace]
convert -font Trebuchet_MS_Bold_Italic.ttf -fill black -pointsize 30 -annotate +$xstart2+$ystart2 "$(cat "drinks/$drink")" 2.png 3.png
cp 3.png 1.png
echo -n "       "
echo $(cat "drinks/$drink")
lines=$[ $(cat "drinks/$drink"|wc -l) * 36 ]
lines=$[lines + 65]
ystart=$[$ystart + $lines]

if [ $ystart -gt 1900 ] ; then ystart=300 ; xstart=$[$xstart + $nextrow]
fi



done
cp 3.png cocktailist.png

Happy at the “bar”

I made a better cocktail bar after this adventure.
Well .. i gave three ladies an orgasm this night, not bad 🙂

I made a very bad playlist .. but I was even dancing the Macarena at 4am.
