This project is intended to be a home automation solution. Conceived from wanting an automated way to open an electronically controlled gate with a rasberry pi and gpio.

Currently it only supports triggering relays via API transaction.

Deployment is on rasbian, the debian variant for rasberry pis. Included is the systemd unit file to run gunicorn as a service. The service is configured to startup with the OS at boot time /etc/systemd/system/pigateman.service To reconfigure this you can run. systemctl enable pigateman or systemctl disable pigateman

The application code is deployed in /opt/pigateman.

The gunicorn processes sit behind a nginx reverse proxy which point to the gunicorn process at 127.0.0.1:8000. The nginx reverse proxy is setup to listen for SSL connections on port 443, and use a SSL certificate from let's encrypt for the applicable domain. The nginx conf file is included in the deployment directory of this repo( deployed to /etc/nginx/sites-enabled/pigateman )

• Copy repo contents to /opt/pigateman
• Update /etc/nginx/sites-enabled/pigateman if applicable. ( be sure to update domain name from example domain name in this file )
• Update /etc/systemd/system/pigateman.service if applicable.
• Run systemctl daemon-reload if the service unit file above was updated.
• Run systemctl restart pigateman to restart the service post update.

There is a python virtual environment for this service in /opt/pigateman/venv. Before making changes to python packages make sure you activate the venv by running source /opt/pigateman/venv/bin/activate

There is a cronjob configured to renew let's encrypt certificates using certbot. 0 0 05 10,26 * ? systemctl stop nginx; certbot certonly --standalone -d yourdomain.com; systemctl start nginx;

• Admin panel is at https://yourdomain.com:yourportnumber/admin
• You can create and manage admin users via django commands https://docs.djangoproject.com/en/2.2/ref/django-admin/#django-admin-createsuperuser

• You can expose this tool to the outside word by forwarding a port on your router to port 443 of the rasberry pi device. It is highly recommended you configure a static ip for this.
• Additionally you can expose port 22( or forward any outside port to 22 ) for others to access the linux system on the device via ssh. (TAKE GREAT CAUTION IN DOING SO, NOT ADVISED)
• Use of a domain is required for the SSL enabled setup. Your internet connection's IP will need to be configured as a DNS A record to your domain of choice.
