LLM Integration — Wired, Not Chatted
Run a local LLM with Ollama in your home automation — summarize sensor data, write alerts, and act on the results offline on your own hardware.

Run a krill server on a Raspberry Pi, a laptop, or a rack box. Open the app on any device on your network. Wire sensors, schedulers, calculations, GPIO and dashboards into a live swarm — no cloud, no accounts, no rented brain. The architecture pros use for SCADA, scaled down to fit on a workbench.

decentralized
Local-first, by design
Servers discover each other on your LAN and pair into a swarm. Your data, your hardware, your network — never anyone else's cloud.
process control
Real automation, not toys
Data points, cron timers, calculations, GPIO, alerts, dashboards — composable nodes wired into directed graphs. Inspired by industrial SCADA.
maker-first
Runs on a Pi
Aquaponics, vivariums, breweries, greenhouses, workshops. Drop a server on a Pi, plug in sensors, build the system you actually wanted.
pro-grade
Architecture pros use
Typed nodes, explicit observer model, deterministic graph evaluation. The same patterns that run factories — without the seat-license bill.

Four minutes. Three nodes. One mental model that scales from a single thermostat to a building's worth of sensors.
