Color Data Points Triggers
Store, visualize, and trigger on color sensor data with the new COLOR data type and Color trigger
Krill
Your home automation should work when the internet doesn't.
Krill is the first decentralized control platform where every sensor, actuator, camera, and logic rule is a node in a self-healing mesh — running on your Raspberry Pis, owned by you, with native apps on every platform.
Built from the ground up in Kotlin Multiplatform. One codebase. Android, iOS, Desktop, Web, and Raspberry Pi. No cloud. No subscription. No single point of failure.
Why Krill
🌐
Zero CloudYour data never leaves your network. No accounts, no subscriptions, no vendor lock-in.
🕸
Mesh SwarmServers auto-discover each other on your LAN. Add a Pi, enter a 4-digit PIN, and it joins the swarm.
⚡
Real PowerLogic gates, Python lambdas, serial sensors, MQTT, GPIO, cameras, color sensors, and 35+ node types — wired together visually.
🎨
Your DashboardA unique force-graph shows live alerts and executions — or design custom SVG dashboards in Inkscape with real-time data and live video overlays.
Everything in Krill is a Node. Nodes react to data changes, execute logic, and control hardware — across any number of servers, in real time.
