A tiny Elixir & Phoenix garage door server for running on a RaspberryPi with Raspbian
This is the 'channel' implementation.
- A dedicated supervised Task is spawned at server startup to monitor the garage door status
- The page loads to an uninitialised state
- When the page joins the channel - an async task is spawned to check the initial state
- State updates always occur via the channel
- Button presses also occur via the channel
(from https://www.npmjs.com/package/homebridge-rasppi-gpio-garagedoor - see this for an important note on pin selection too)
-
Choose the GPIO pins that you are going to use, following the above information
-
Export the GPIO pins to be used and set their direction after reboot
-
Copy and edit this start script into your /etc/init.d directory.
-
Change the values to be the gpio pins that you are using.
-
chmod 755 /etc/init.d/garage-door-gpio # this makes the script executable
-
sudo update-rc.d /etc/init.d/garage-door-gpio defaults # this will set up the symlinks to run the script on startup.
-
sudo /etc/init.d/garage-door-gpio start and verify that your pins are exported by looking in ls /sys/class/gpio/ directory
-
Edit config.exs for your garage setup (GPIO pins)
To start your Phoenix app:
- Install dependencies with
mix deps.get - Install Node.js dependencies with
npm install - Start Phoenix endpoint with
mix phoenix.server
Now you can visit localhost:4000 from your browser.
