Taking back control of your life with Nerves
summary
A mocha-pot monitor uses a Bosch humidity sensor, a physical button, a GPIO LED and a Raspberry Pi 3 to send an SMS when coffee is ready, with the app written in Elixir on Nerves. Firmware builds as a 35 MB firmware image and deploys over-the-air via Nerves Hub, the device supports remote iex and dual-partition safe flashing, and the demo shows a single-device flow that is designed to scale to fleets while keeping full local control of sensors and code.
