This guide is for using a Twitter bash script with Domoticz, to tweet the data of your weather sensors.
THIS GUIDE IS "WORK IN PROGRESS"

Example of an Domoticz Twitter weather station
Create a Twitter account
First you need to create a Twitter account here
- Name: Choose a name for your "weather station".
- E-mail: Your e-mail address.

Getting the Twitter script

Setting up the Twitter script
First you need to add some pieces of script to get temperature ect.
You don't need to create weather.txt in the scripts folder. Will be done by the script.
In this example I use an sensor with both temperature and humidity combined.
Add on top of tweet.sh
To extract temperature from Domoticz:
thermo=`curl "http://api_username:api_password@domoticz_server:domoticz_port/json.htm?type=devices&rid=your_id"` echo $thermo > /home/pi/domoticz/scripts/weather.txt temperature=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $13, $14}' | awk '{print $3}' | sed 's/\"//g'`
If you are using separated sensors for temperature and humidity. You should edit the first "awk -F: '{print $13, $14}'" and play with the number 13 and 14.
Add under the temperature, to extract the humidity from Domoticz:
hygro=`curl "http://api_username:api_password@domoticz_server:domoticz_port/json.htm?type=devices&rid=your_id"` echo $hygro > /home/pi/domoticz/scripts/weather.txt hygro=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $14, $15}' | awk '{print $3}' | sed 's/\"//g'`
If you are using separated sensors for temperature and humidity. You should edit the first "awk -F: '{print $13, $14}'" and play with the number 13 and 14.
Add under the humidity, to extract the rain from Domoticz:
rain=`curl "http://api_username:api_password@domoticz_server:domoticz_port/json.htm?type=devices&rid=your_id"` echo $rain > /home/pi/domoticz/scripts/weather.txt rain=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $24, $25}' | awk '{print $3}' | sed 's/\"//g' | sed 's/,//g'`
Add under the rain, to extract the wind from Domoticz:
wind=`curl "http://api_username:api_password@domoticz_server:domoticz_port/json.htm?type=devices&rid=your_id"` echo $wind > /home/pi/domoticz/scripts/weather.txt dir=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $11, $12}' | awk '{print $3}' | sed 's/\"//g' | sed 's/,//g'` speed=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $24, $25}' | awk '{print $3}' | sed 's/\"//g' | sed 's/,//g'`
Add this piece of script under the wind:
tweet="Temperature in #Amsterdam: $temperature°C #change to what you want but keep "$temperature" Humidity: $hygro% #change to what you want but keep "$hygro" Rain: $rain mm #change to what you want but keep "$rain" Wind: $dir / $speed km/h" #change to what you want but keep "$dir and $speed" rm /home/pi/domoticz/scripts/weather.txt #will remove the weather.txt file
Fill in your username (e-mail address) and password at:
#REQUIRED PARAMS username="username" password="password"
Change this in the original script under password
tweet="$*" to tweet="$tweet"
Final Twitter script
This is what your Twitter script should look like:
#!/bin/bash
#Twitter status update bot by http://360percents.com
#Author: Luka Pusic <[email protected]>
thermo=`curl "http://api_username:api_password@domoticz_server:domoticz_port/json.htm?type=devices&rid=your_id"`
echo $thermo > /home/pi/domoticz/scripts/weather.txt
temperature=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $13, $14}' | awk '{print $3}' | sed 's/\"//g'`
hygro=`curl "http://api_username:api_password@domoticz_server:domoticz_port/json.htm?type=devices&rid=your_id"`
echo $hygro > /home/pi/domoticz/scripts/weather.txt
hygro=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $14, $15}' | awk '{print $3}' | sed 's/\"//g'`
rain=`curl "http://api_username:api_password@domoticz_server:domoticz_port/json.htm?type=devices&rid=your_id"`
echo $rain > /home/pi/domoticz/scripts/weather.txt
rain=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $24, $25}' | awk '{print $3}' | sed 's/\"//g' | sed 's/,//g'`
wind=`curl "http://api_username:api_password@domoticz_server:domoticz_port/json.htm?type=devices&rid=your_id"`
echo $wind > /home/pi/domoticz/scripts/weather.txt
dir=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $11, $12}' | awk '{print $3}' | sed 's/\"//g' | sed 's/,//g'`
speed=`cat /home/pi/domoticz/scripts/weather.txt | awk -F: '{print $24, $25}' | awk '{print $3}' | sed 's/\"//g' | sed 's/,//g'`

Save your script at /domoticz/scripts/ as tweet.sh
Make script executable and add to crontab
Make tweet.sh executable with the following commands via SSH
cd domoticz/scripts chmod +x tweet.sh
Check if the script is executable
./tweet.sh
Should show this in SSH:

[+] Getting compose tweet page...
[+] Posting a new tweet: Temperatuur in #Hem: 1.5°C

Finally add the script to crontab in SSH
crontab -e
add this line (for every hour a tweet)
0 * * * * /home/pi/domoticz/scripts/tweet.sh
And save the crontab.
Check if the crontab is safed by:
crontab -l
The line should be present.
