GateOpener is exactly what the name implies: Its a piece of software that allows you to open a gate (or whatever electronic device) normally operated with a switch. You can control the device using your computer or phone simply by sending a HTTP-request to the webserver. To close the gap between your computer and the device you are trying to control you only need a raspberry pi or similar device. Because its docker based the setup is as easy as it could be, just start the image on your raspberry pi and you are ready to go.

Whats the device you are always missing? Your remote. Whats the one device you always have on your hand? Youre phone. Thats why.

• Raspberry Pi or similar with a running instance of docker
• An electronic controllable switch (Relais, Optocoupler, Transistor whatever)
• A device you want to control

Connect your controllable switch to the raspberry pi and your device. By default the GPIO Pin 2 of the pi is used, but you can change it using the GATE_PIN environment variable.

By default the app runs on port 8000. You can change the port using BACKEND_PORT. You need to perform some configuration, for that its best to create an env file like the following:

USERNAME= # The username you want to login with
PASSWORD= # The password for the specified user
GATE_PIN= # The gpio pin of your raspberry pi
BACKEND_PORT= # Defaults to 8000
SECRET_KEY= # Optional: Provide an own secret key, otherwise one is generated using openssl rand -hex 32

docker run --device /dev/gpiomem -p 80:80 -d --env-file .env niklasrittmann/gate_opener:0.0.1

• Authentification
• Enable Https
• Add status endpoint
