Raspberry Pi GPIO Pins
Control Raspberry Pi GPIO pins for digital input/output and PWM operations.
Designed for Raspberry Pi enthusiasts, Krill is a unique approach to automation and control with a collection of apps to visualize and connect your systems at any scale.
Built with security and privacy first, you can build Krill Swarms without an account or internet connection and control your devices and process data with our Linux Desktop, Android and Web Interface.
View your swarm in real time node graphs or create custom SVG dashboards with live overlays of processes, states and data.

Control Raspberry Pi GPIO pins for digital input/output and PWM operations.
Send HTTP requests to external systems for integration and notifications.
Control devices and IoT applications using MQTT protocol with publish/subscribe messaging.
Trigger workflows when data point values fall below a specified threshold.
Boolean logic operations (AND, OR, NOT, XOR, etc.) for conditional automation workflows.
Execute custom Python scripts for advanced automation and data processing.
Trigger workflows when data point values exceed a specified threshold.
Data Points are created to store a series of data values over time with millisecond-level logging on the host server's file system.
Filter and clean sensor data with Deadband, Debounce, Discard Above, and Discard Below filters.
Trigger workflows on a schedule using cron expressions for time-based automation.
