Use a Raspberry Pi to read the temperature from a sensor, store it and show some graphs. Then a thermostat software is used to switch on/off a boiler, so a constant target temperature can be mantained at home.

Coming soon

Install MySQL DB:

sudo apt-get install mysql-server
sudo apt-get install libmysqlclient-dev

mysql -u root -p

create database home_temperature;
create user 'home'@'localhost' identified by 'temperature';
grant all privileges on home_temperature.* TO 'home'@'localhost' identified by 'temperature';

Load 1-wire bus kernel modules:

sudo modprobe w1_gpio 
sudo modprobe w1_therm

For loading the modules at boot time:

sudo vi /etc/modules
w1_gpio
w1_therm

sudo vi /boot/config.txt
dtoverlay=w1-gpio

Install python libraries and run the server

sudo apt-get install python-pip
sudo pip install virtualenv

git clone https://github.com/smallo/home-temperature
cd home-temperature

virtualenv ./tmp/venv/home-temperature
source ./tmp/venv/home-temperature/bin/activate
pip install -r requirements.txt 
python manage.py syncdb
python manage.py loaddata temperature/fixtures/configuration.json

Live:

sudo su
./runserver.sh
./take_samples.sh

Note:

• sudo it's required by RPi.GPIO

Development environment (sqlite instead of MySQL and uses mocks for temperature reader and GPIO): python manage.py runserver --setting=home_temperature.settings_dev

Or if you want to listen to all network interfaces: python manage.py runserver 0.0.0.0:8000 --setting=home_temperature.settings_dev

In order to runserver and take_samples to run when the system starts up:

sudo su
cp ./scripts/home-temperature-runserver /etc/init.d
update-rc.d home-temperature-runserver defaults

cp ./scripts/home-temperature-take-samples /eyc/init.d
update-rc.d home-temperature-take-samples defaults
