An Elixir app to a small hydropower plant
summary
Elixir runs SCADA on custom Nerves machines based on BeagleBone Green, replacing fragile Raspberry Pi and offloading PLC-style regulation/protection to separate CPU modules; one plant uses a 145 kW generator producing ~800,000 kWh/year, others are ~50 kW and ~20 kW. Two Nerves boxes link over optical fiber, talk to the PLC via modbus TCP + MQTT/HTTP and send cloud logs. Hardware is Nerves on BeagleBone Green with three module types, PoE and eMMC, IEC 61131-2 stress-tested and delivered by web engineers on a production schedule.
