Use your weather sensors with Twitter

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"

Original forum post

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.
- Password: Your password.
- Username: Use something like "WeatherInAmsterdam".

Getting the Twitter script

This is the original scripts from 360Percents
tweet.sh

 if [ $(echo "$tweet" | wc -c) -gt 140 ]; then

 	echo "[FAIL] Nothing to tweet. Enter your text as argument." && exit 1

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, begin under #Author: Luka Pusic <pusic93@gmail.com>
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/temperatur.txt | awk -F: '{print $11, $12}' | awk '{print $3}' | sed 's/\"//g' | sed 's/,//g'`
speed=`cat /home/pi/domoticz/scripts/temperatur.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 <pusic93@gmail.com>
 
 thermo=`curl "http://api_username:api_password@domoticz_server:domoticz_port/json.htm?type=devices&rid=your_id"`

 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/temperatur.txt | awk -F: '{print $11, $12}' | 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:

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.
