Silvia

This project contains my mods for a Rancilio Silvia espresso machine.

This project is using Nerves and Phoenix LiveView.

Currently the versions included are:

• nerves - 1.11.1
• phoenix - 1.7.18
• phoenix_liveview - 1.0.1
• tailwindcss - 0.2.3

Configuration

The order of configuration is loaded in a specific order:

• config.exs
• host.exs or target.exs based on MIX_TARGET
• prod.exs, dev.exs, or test.exs based on MIX_ENV
• runtime.exs at runtime

To make configuration slightly more straightforward, the application is run with MIX_ENV=prod when on the device. Therefore, the configuration for phoenix on the target device is in the prod.exs config file.

Flashing to a Device

You can burn the first image with the following commands:

./scripts/deploy.sh

Roadmap

The next few steps are:

• Get the heat sensor (TSIC 306) working so we can detect the heat of the boiler
• Introduce the relay to control the heating element (get it working)
• Introduce the PID (pid_controller) library and understand how it works
• Insulate the boiler on the physical machine
• Implement the PID
• Work on the UI for the Dashboard
